In the Senate , Bradley acquired a reputation for being somewhat aloof and was thought of as a " policy <unk> " , specializing in complex reform initiatives . Among these was the 1986 overhaul of the federal tax code , co @-@ sponsored with Dick Gephardt , which reduced the tax rate schedule to just two brackets , 15 percent and 28 percent , and eliminated many kinds of deductions . Domestic policy initiatives that Bradley led or was associated with included reform of child support enforcement ; legislation concerning lead @-@ related children 's health problems ; the Earned Income Tax Credit ; campaign finance reform ; a re @-@ apportioning of California water rights ; and federal budget reform to reduce the deficit , which included , in 1981 , supporting Reagan 's spending cuts but opposing his parallel tax cut package , one of only three senators to take this position . He sponsored the Freedom Support Act , an exchange program between the republics of the former Soviet Union and the United States .
Bradley was re @-@ elected in 1984 with 65 percent of the vote against Montclair mayor Mary V. <unk> . In 1988 , he was encouraged to seek the Democratic nomination for President , but he declined to enter the race , saying that he would know when he was ready . In 1990 , a controversy over a state income tax increase — on which he refused to take a position — and his proposal on merit pay for teachers , which led the <unk> to support his opponent , turned his once @-@ obscure rival for the Senate , Christine Todd Whitman , into a viable candidate , and Bradley won by only a slim margin . In 1995 , he announced he would not run for re @-@ election , publicly declaring American politics " broken . "
While he was a senator , Bradley walked the beaches from Cape May to Sandy Hook , a four @-@ day , 127 @-@ mile trip each Labor Day weekend , to assess beach and ocean conditions and talk with constituents . Bradley was criticized for neglecting constituent services while in office .

Bradley ran in the 2000 presidential primaries , opposing incumbent Vice President Al Gore for his party 's nomination . Bradley campaigned as the liberal alternative to Gore , taking positions to the left of Gore on a number of issues , including universal health care , gun control , and campaign finance reform . On the issue of taxes , Bradley trumpeted his sponsorship of the Tax Reform Act of 1986 , which had significantly cut tax rates while abolishing dozens of loopholes . He voiced his belief that the best possible tax code would be one with low rates and no loopholes , but he refused to rule out the idea of raising taxes to pay for his health care program , calling the idea of such a pledge " dishonest " .
On public education , he proposed to make over $ 2 billion in block grants available to each state every year . He further promised to bring 60 @,@ 000 new teachers into the education system in hard @-@ to @-@ staff areas over ten years by offering college scholarships to anyone who agreed to become a teacher after graduating ; Gore offered a similar proposal .
Bradley also made child poverty a significant issue in his campaign . He promised to address the minimum wage , expand the Earned Income Tax Credit , allow single parents on welfare to keep their child support payments , make the Dependent Care Tax Credit refundable , build support homes for pregnant teenagers , enroll 400 @,@ 000 more children in Head Start , and increase the availability of food stamps .
Although Gore was considered the party favorite , Bradley received a number of high @-@ profile endorsements , including senators Paul Wellstone , Bob Kerrey , and Daniel Patrick Moynihan ; former Secretary of Labor Robert Reich ; former New York City mayor Ed Koch ; former Federal Reserve chairman Paul Volcker ; and basketball stars Michael Jordan and Phil Jackson . Bradley and Jackson have been close friends since they were teammates playing for the New York Knicks . Jackson was a vocal supporter of Bradley 's run for the presidency and often wore his campaign button in public . He announced his acceptance of the position of head coach of the Los Angeles Lakers while Bradley was campaigning in California in 1999 , and he was a " regular draw on the Bradley money trail " during the campaign . Bradley later called it a " great honor " to be the presenter when Jackson was inducted into the Naismith Memorial Basketball Hall of Fame in 2007 .
In March 2000 , after failing to win any of the first 20 primaries and caucuses in the election process , Bradley withdrew his campaign and endorsed Gore ; he ruled out the idea of running as the vice @-@ presidential candidate and did not answer questions about possible future runs for the presidency . He said that he would continue to speak out regarding his brand of politics , calling for campaign finance reform , gun control , and increased health care insurance .

Later in 2000 , Bradley was offered the chairmanship of the United States Olympic Committee , which he turned down . In September 2002 , Bradley turned down a request from New Jersey Democrats to replace Robert Torricelli on the ballot for his old Senate seat , which another former senator , Frank Lautenberg , accepted . Oxford University awarded Bradley an honorary Doctor of Civil Law ( DCL ) in 2003 , with a citation that described him in part as " ... an outstandingly distinguished athlete , a weighty pillar of the Senate , and still a powerful advocate of the weak ... " . In 2007 Bradley was awarded the Distinguished Eagle Scout Award . This award is given in recognition of community service more than 25 years after a scout first earns the Eagle badge .
In January 2004 , Bradley and Gore both endorsed Howard Dean for President in the 2004 Democratic primaries . In January 2008 , Bradley announced that he was supporting Barack Obama in the 2008 Democratic primary . He campaigned for Obama and appeared on political news shows as a surrogate . Bradley 's name was mentioned as a possible replacement for Tom Daschle as nominee for Secretary of Health and Human Services in the Obama administration after Daschle withdrew from consideration ; the position went to Kansas governor Kathleen Sebelius . He has occasionally been involved in political matters , most recently consulting the Senate Finance Committee on tax reform along with former colleague Bob Packwood
He has worked as a corporate consultant and investment banker . He has been a managing director of Allen & Company LLC , since 2001 , was chief outside advisor to McKinsey & Company 's nonprofit division , the McKinsey Global Institute , from 2001 to 2004 , and is a member of the board of directors of <unk> and Starbucks and the private company <unk> . Bradley is a senior advisor to the private equity firm <unk> Partners . Bill Bradley is also a board member of <unk> , an online charity that connects individuals to classrooms in need . He is also the Chair of the Advisory Council for Acumen Fund , a non @-@ profit global venture fund that uses entrepreneurial approaches to solve the problems of global poverty . Bradley is also a Co @-@ Chair for the Advisory Board of Issue One , a non @-@ profit whose goal is to reduce the influence of money in American politics .

= Al @-@ Mu 'tasim =
Abū <unk> Muḥammad ibn <unk> al @-@ <unk> ( Arabic : أبو إسحاق محمد بن <unk> <unk> ; October 796 – 5 January 842 ) , better known by his regnal name al @-@ <unk> bi ’ <unk> ( <unk> بالله , " he who seeks refuge in God " ) , was the eighth Abbasid caliph , ruling from 833 to his death in 842 . A son of Harun al @-@ Rashid , he succeeded his half @-@ brother al @-@ Ma 'mun , under whom he had served as a military commander and governor . His reign was marked by the introduction of the Turkish slave @-@ soldiers ( ghilmān or <unk> ) and the establishment for them of a new capital at Samarra . This was a watershed in the Caliphate 's history , as the Turks would soon come to dominate the Abbasid government , eclipsing the Arab and Iranian elites that had played a major role in the early period of the Abbasid state . Domestically , al @-@ Mu 'tasim continued al @-@ Ma 'mun 's support of Mu 'tazilism and its inquisition ( miḥna ) , and centralised administration , reducing the power of provincial governors in favour of a small group of senior civil and military officials in Samarra . Al @-@ Mu 'tasim 's reign was also marked by continuous warfare , both against internal rebellions like the Khurramite revolt of Babak Khorramdin or the uprising of Mazyar of Tabaristan , but also against the Byzantine Empire , where the Caliph personally led the celebrated Sack of Amorium , which secured his reputation as a warrior @-@ caliph .
= = Early life = =
The future al @-@ Mu 'tasim was born to the Caliph Harun al @-@ Rashid ( ruled 786 – 809 ) and <unk> , a Turkic slave concubine . He was born in the <unk> ( " Eternity " ) Palace in Baghdad , but the date is unclear : according to al @-@ Tabari , his birth was placed by various authorities either in October 796 ( Sha <unk> AH 180 ) , or earlier , in AH 179 ( i.e. spring 796 or earlier ) . Al @-@ Tabari describes the adult al @-@ Mu 'tasim as " fair @-@ complexioned , with a black beard the hair tips of which were red and the end of which was square and streaked with red , and with handsome eyes " , while other authors stress his physical strength and the fact that he was almost illiterate .
As one of Harun 's younger sons , he was initially of little consequence . During the civil war between his elder half @-@ brothers al @-@ Amin ( r . 809 – 813 ) and al @-@ Ma 'mun ( r . 813 – 833 ) he remained in Baghdad , and , like most members of the Abbasid dynasty and the Abbasid aristocracy ( abnāʾ al @-@ dawla ) , supported the anti @-@ caliph Ibrahim ibn al @-@ Mahdi in 817 – 819 . Al @-@ Tabari records that Abu Ishaq led the pilgrimage in 816 , accompanied by many troops and officials , among whom was <unk> ibn Ali ibn Isa ibn <unk> , who had just been appointed to the governorship of the Yemen and was on his way there . During his stay in Mecca , his troops defeated and captured a pro @-@ Alid leader who had raided the pilgrim caravans . He also led the pilgrimage in the next year , but no details are known .
From ca . 814 / 5 , Abu Ishaq began forming his corps of Turkish troops . The first members of the corps were domestic slaves he bought in Baghdad ( the distinguished general Itakh was originally a cook ) whom he trained in the art of war , but they were soon complemented by Turkish slaves sent directly from Central Asia after an agreement with the local Samanid rulers . This private force was small — it probably numbered between three and four thousand at the time of his accession — but it was highly trained and disciplined , and made Abu Ishaq a man of power in his own right , as al @-@ Ma 'mun increasingly turned to him for assistance . Abu Ishaq 's Turkish corps was also politically useful to al @-@ Ma 'mun , who aimed to lessen his own dependence on the mostly eastern Iranian leaders who had supported him in the civil war , and who now occupied the senior positions in the new regime . In an effort to counterbalance their influence , al @-@ Ma 'mun granted formal recognition to his brother and his Turkish corps , as well as placing the Arab tribal levies of the <unk> in the hands of his own son , al @-@ Abbas .
The nature and identity of al @-@ Mu 'tasim 's " Turkish slave soldiers " is a controversial subject , with both the ethnic label and the slave status of its members disputed . Although the bulk of the corps were clearly of servile origin , being either captured in war or purchased as slaves , in the sources they are never referred to as slaves ( <unk> or <unk> ) , but rather as mawālī ( " clients " or " freedmen " ) or ghilmān ( " pages " ) , implying that they were manumitted , a view reinforced by the fact that they were paid cash salaries . In addition , although the corps are collectively called simply " Turks " , <unk> , in the sources , prominent early members were neither Turks nor slaves , but rather Iranian vassal princes from Central Asia like al @-@ Afshin , prince of Usrushana , who were followed by their personal retinues ( Persian <unk> , Arabic <unk> ) .
Al @-@ Tabari mentions that in 819 Abu Ishaq commanded a force sent against some Kharijite rebels . During this campaign , one of the Turkish ghilmān placed himself between a Kharijite lancer and the future caliph , shouting , " Recognize me ! " ( in Persian " <unk> ma @-@ ra " ) . To express his appreciation , Abu Ishaq on that same day granted this man the name Ashinas . In 828 , al @-@ Ma 'mun appointed Abu Ishaq as governor of Egypt and Syria in place of Abdallah ibn Tahir , who departed to assume the governorship of Khurasan , while the Jazira and the frontier zone ( <unk> ) with the Byzantine Empire passed to al @-@ Abbas . Egypt had just been brought back under caliphal authority and pacified after the tumults of the civil war with Ibn Tahir , but the situation remained volatile . When Abu Ishaq 's governor , Umayr ibn al @-@ Walid , tried to raise taxes , the Nile Delta and <unk> regions rose in revolt . In 830 , Umayr tried to forcibly subdue the rebels , but was ambushed and killed along with many of his troops . With the government troops now confined to the capital Fustat , Abu Ishaq intervened in person , at the head of his 4 @,@ 000 Turks . The rebels were soundly defeated and their leaders executed . In 831 , however , soon after his departure , the revolt flared up again , this time encompassing both the Arab settlers and the native Christian Copts under the leadership of Ibn <unk> , a descendant of one of the original Arab conquerors of the country . The rebels were confronted by the Turks , led by Afshin , who engaged in a systematic campaign , winning a string of victories and engaging in large @-@ scale executions . Thus the male Copts were executed , and their women and children sold into slavery , while the old Arab elites who had ruled the country since the Muslim conquest of Egypt were practically annihilated . In early 832 , al @-@ Ma 'mun visited the province , and soon after that the last bastion of resistance , the Copts of the coastal marshes , were subdued .
In July – September 830 , al @-@ Ma 'mun , encouraged by perceived Byzantine weakness and suspicious of collusion between Emperor Theophilos and the Khurramite rebels of Babak Khorramdin , launched the first large @-@ scale invasion of Byzantine territory since the start of the Abbasid civil war , and sacked a number of Byzantine border fortresses . Following his return from Egypt , Abu Ishaq joined al @-@ Ma 'mun in his 831 campaign against the Byzantines . After rebuffing Theophilos ' offers of peace , the Abbasid army crossed the Cilician Gates and divided into three columns , with the Caliph , his son Abbas , and Abu Ishaq at their head . The Abbasids seized and destroyed several minor forts and the town of Tyana , while Abbas even won a minor skirmish against Theophilos in person , before withdrawing to Syria in September . In 832 al @-@ Ma 'mun repeated his invasion of the Byzantine borderlands , capturing the strategically important fortress of <unk> , a success that consolidated Abbasid control of both exits of the Cilician Gates . So encouraged was al @-@ Ma 'mun by this victory that he repeatedly rejected Theophilos ' ever more generous offers for peace , and publicly announced that he intended to capture Constantinople itself . Consequently Abbas was dispatched in May to convert the deserted town of Tyana into a military colony and prepare the ground for the westwards <unk> al @-@ Ma 'mun followed in July , but he suddenly fell ill and died on 7 August 833 .
= = Caliphate = =
On his deathbed , al @-@ Ma 'mun dictated a letter nominating his brother , rather than his son al @-@ Abbas , as his successor . This appointment owed much to Abu Ishaq 's strong personality and leadership skills , but also because he was the only Abbasid prince to control independent military power in the form of his Turkish corps , on which al @-@ Ma 'mun had come to increasingly depend . Consequently , Abu Ishaq was acclaimed as Caliph on 9 August , with the name of al @-@ Mu 'tasim . His position was far from secure , however , as a large part of the army favoured al @-@ Ma 'mun 's son Abbas , and even tried to proclaim him as the new Caliph . Consequently al @-@ Mu 'tasim called off the expedition , abandoned the Tyana project and returned with his army to Baghdad , which he reached on 20 September .
= = = New elites and administration = = =
The rise of al @-@ Mu 'tasim to the caliphate was a watershed moment in the history of the Abbasid state , heralding a radical change in the nature of its administration . Unlike his brother , who tried to use the Arabs and Turks to balance out the Iranian troops , al @-@ Mu 'tasim relied almost exclusively on his Turks , and established " a new regime that was militaristic and centred on the Turkish corps " ( Tayeb El @-@ Hibri ) . This was a decision with long @-@ lasting repercussions in Islamic history . Not only did the military acquire a predominant position , but it also increasingly became the preserve of minority groups from the peoples living on the margins of the Islamic world . Thus it formed an exclusive ruling caste , separated from the Arab @-@ Iranian mainstream of society by ethnic origin , language , and sometimes even religion . This dichotomy would become a " distinctive feature " ( Hugh N. Kennedy ) of many Islamic polities , and would culminate in the Mamluk dynasties that ruled Egypt and Syria in the late Middle Ages .
Although the new professional army proved militarily highly effective , it also posed a potential danger to the stability of the Abbasid regime : the army 's separation from mainstream society meant that the soldiers were entirely reliant on their cash salary ( ʿaṭāʾ ) for their very survival . Consequently , any failure to provide their pay or policies that threatened their position were likely to cause a violent reaction , as became evident a generation later during the " Anarchy at Samarra " . The need to cover military spending would henceforth be a fixture of caliphal government , and that at a time when government income began to decline rapidly — partly through the rise of autonomous dynasties in the provinces and partly through the decline in productivity of the lowlands of Iraq that had traditionally provided the bulk of tax revenue . Eventually , this would lead to the bankruptcy of the Abbasid government and the eclipse of the caliphs ' political power with Ibn Ra 'iq 's rise to the position of amīr al @-@ <unk> in 935 .
Al @-@ Mu 'tasim 's accession thus signalled the decline of the previous Arab and Iranian elites , both in Baghdad and the provinces , and an increasing centralisation of administration around the caliphal court . A characteristic example is that of Egypt , where the Arab settler families , who still nominally formed the country 's army ( jund ) and continued to receive a salary from the local revenues . Al @-@ Mu 'tasim discontinued the practice , removing the Arab families from the army registers ( <unk> ) and ordering that the revenues of Egypt be sent to the central government , which would then pay the ʿaṭāʾ only to the Turkish troops stationed in the province .
Al @-@ Mu 'tasim 's reliance on his ghilmān would increase in the aftermath of an abortive plot against him during the Amorium campaign in 838 . Headed by ' Ujayf ibn ' Anbasa , a long @-@ serving Khurasani who had served al @-@ Ma 'mun since the civil war against al @-@ Amin , the conspiracy rallied the traditional Abbasid elites , dissatisfied with al @-@ Mu 'tasim 's policies and especially his favouritism towards to the Turks . The plotters aimed to kill the Caliph and raise al @-@ Ma 'mun 's son al @-@ Abbas in his stead . According to al @-@ Tabari , al @-@ Abbas , although privy to these designs , rejected Ujayf 's urgent suggestions to kill al @-@ Mu 'tasim during the initial stages of the campaign , and the plot was soon uncovered . Al @-@ Abbas was imprisoned , and the Turkish leaders Ashinas , Itakh , and Bugha the Elder undertook to uncover and arrest the other conspirators . The affair was the signal for a large @-@ scale purge of the army of the remaining senior Iranian and abnāʾ officials and commanders — according to the Kitab al- ' Uyun , some seventy commanders were executed — while the influence of the Turkish leaders , who remained conspicuously loyal to al @-@ Mu 'tasim throughout the affair , correspondingly increased . The one exception to this purge of the Iranian element were the Tahirids , who remained in place as governors of their Khurasani super @-@ province , encompassing most of the eastern Caliphate . In addition , the Tahirids provided the governor of Baghdad , a focus of opposition to the Caliph under al @-@ Ma 'mun , which helped keep the city quiescent . The post was held throughout al @-@ Mu 'tasim 's reign by Ishaq ibn Ibrahim ibn Mus 'ab , who was " always one of al @-@ Mu 'tasim 's closest advisers and confidants " ( C. E. Bosworth ) .
Another departure from previous practice was al @-@ Mu 'tasim 's appointment of his senior lieutenants , such as Ashinas or Itakh , as nominal super @-@ governors over several provinces . This measure probably intended to allow his chief followers immediate access to funds with which to pay their troops , but also , according to Hugh Kennedy , " represented a further centralizing of power , for the under @-@ governors of the provinces seldom appeared at court and played little part in the making of political decisions " . Indeed , al @-@ Mu 'tasim 's caliphate marks the apogee of the central government 's authority , in particular as expressed in its right and power to extract taxes from the provinces , an issue that had been controversial and had faced much local opposition since the early days of the Islamic state .
Apart from the Turkish military and the Tahirids , al @-@ Mu 'tasim 's administration depended on the central fiscal bureaucracy . As the main source of revenue were the rich lands of southern Iraq ( the Sawad ) and neighbouring areas , the administration was staffed mostly with men drawn from these regions . The new caliphal bureaucratic class that emerged under al @-@ Mu 'tasim were thus mostly Persian or Aramean in origin , with a large proportion of newly converted Muslims and even a few Nestorian Christians , who came from landowner or merchant families . From his accession until 836 , al @-@ Mu 'tasim 's chief minister or vizier was his old personal secretary al @-@ Fadl ibn Marwan , distinguished for his caution and frugality . His replacement , Muhammad ibn al @-@ Zayyat , was of a completely different character : a rich merchant , he is described by Hugh Kennedy as " a competent financial expert but a callous and brutal man who made many enemies " , even among his fellow members of the administration . Nevertheless , and even though his political authority never exceeded the fiscal domain , he managed to maintain his office throughout the reign , and under al @-@ Mu 'tasim 's successor al @-@ <unk> ( ruled 842 – 847 ) as well .
= = = Foundation of Samarra = = =
The Turkish army was at first quartered in Baghdad , but quickly came into conflict with the remnants of the old Abbasid establishment in the city ( the abnāʾ ) and the city 's populace , who resented their loss of influence to the foreign troops . This was a major factor in al @-@ Mu 'tasim 's decision in 836 to found a new capital at Samarra , some 80 miles ( 130 km ) north of Baghdad , but there were other considerations at play as well . Founding a new capital was a public statement of the establishment of a new regime , while allowing the court to be " at a distance from the populace of Baghdad and protected by a new guard of foreign troops , and amid a new royal culture revolving around sprawling palatial grounds , public spectacle and a seemingly ceaseless quest for leisurely indulgence " ( Tayeb El @-@ Hibri ) , an arrangement compared by Oleg Grabar to the relationship between Paris and Versailles after Louis XIV . In addition , by creating a new city in a previously uninhabited area , al @-@ Mu 'tasim could reward his followers with land and commercial opportunities without cost to himself and free from any constraints , unlike Baghdad with its established interest groups . In fact , the sale of land seems to have produced considerable profit for the treasury — in the words of Hugh Kennedy , " a sort of gigantic property speculation in which both government and its followers could expect to benefit " .
Space and life in the new capital were strictly regimented : residential areas were separated from the markets , and the military was given its own cantonments , separated from the ordinary populace and each the home of a specific ethnic contingent of the army ( e.g. the Turks , <unk> , Maghariba and <unk> regiments ) . The city was dominated by its mosques ( most famous among which is the Great Mosque of Samarra built by Caliph al @-@ Mutawakkil ) and palaces , built in grand style by both the caliphs and their senior commanders , who were given extensive properties on the site . Unlike Baghdad , however , the new capital was an entirely artificial creation . Poorly sited in terms of water supply and river communications , its existence was determined solely by the presence of the caliphal court , and when the capital returned to Baghdad , sixty years later , Samarra rapidly declined .
= = = Mu 'tazilism and the miḥna = = =
Ideologically , al @-@ Mu 'tasim followed the footsteps of al @-@ Ma 'mun , continuing his predecessor 's support for Mu 'tazilism , a theological doctrine that attempted to tread a middle way between secular monarchy and the theocratic nature of rulership espoused by the Alids and the various sects of Shi 'ism . Mu <unk> espoused the view that the Quran was created and hence fell within the authority of a God @-@ guided <unk> to interpret according to the changing circumstances . While revering Ali , they also avoided taking a position on the righteousness of the opposing sides in the conflict between Ali and his opponents . Mu 'tazilism was officially adopted by al @-@ Ma 'mun in 827 , and in 833 , shortly before his death , al @-@ Ma 'mun made its doctrines compulsory , with the establishment of an inquisition , the miḥna . Al @-@ Mu 'tasim played an active role in the enforcement of the miḥna in the western provinces , and continued on the same course after his accession : the chief advocate of Mu 'tazilism , the head <unk> Ahmad ibn Abi <unk> , was perhaps the dominant influence at the caliphal court throughout al @-@ Mu 'tasim 's reign .
Thus Mu 'tazilism became closely identified with the new regime of al @-@ Mu 'tasim , and adherence to Mu 'tazilism was transformed into an intensely political issue : to question it was to oppose the authority of the Caliph as the God @-@ sanctioned <unk> . While Mu 'tazilism found broad support , it was also passionately opposed by traditionalists , who held that the Quran 's authority was absolute and unalterable as the word of God , as well as providing a vehicle for criticism by those who disliked the new regime and its elites . In the event , the active repression of the traditionalists was without success , and even proved counterproductive : the beating and imprisonment of one of the most resolute opponents of Mu 'tazilism , Ahmad ibn <unk> , in 834 , only helped to spread his fame , and by the time Caliph al @-@ Mutawakkil abandoned Mu 'tazilism and returned to traditional orthodoxy in 848 , the strict and conservative Hanbali school had emerged as the leading school of jurisprudence ( fiqh ) in Sunni Islam .
Al @-@ Mu 'tasim continued the patronage of scientists and translators , and Baghdad remained a major centre of learning throughout his reign . Among the notable scholars active during his reign were the astronomers Habash al @-@ <unk> al @-@ <unk> and Ahmad al @-@ Farghani , the polymath al @-@ Jahiz , and the distinguished Arab mathematician and philosopher al @-@ Kindi , who dedicated his work On First Philosophy to his patron al @-@ Mu 'tasim .
= = = Campaigns = = =
Although al @-@ Mu 'tasim 's reign was a time of peace in the Caliphate 's heartland territories , al @-@ Mu 'tasim himself was an energetic campaigner , and " acquired the reputation of being one of the warrior @-@ caliphs of Islam " . With the exception of the Amorium campaign , most of the military expeditions of al @-@ Mu 'tasim 's reign were domestic , directed against rebels and areas that , although nominally part of the Caliphate , had remained outside effective Muslim rule and where native peoples and princes retained de facto autonomy .
= = = = Domestic campaigns = = = =
An Alid revolt led by Muhammad ibn Qasim broke out in Khurasan in early 834 , but was swiftly defeated and Muhammad brought as a prisoner to the Caliph 's court . He managed to escape during the night of 8 / 9 October 834 , taking advantage of the Eid al @-@ Fitr festivities , and was never heard of again . In June / July of the same year , ' Ujayf ibn ' Anbasa was sent to subdue the Zutt . These were people brought from India by the Sassanid emperors and settled in the Mesopotamian Marshes . The Zutt had rebelled against caliphal authority since ca . 820 , and had been regularly raiding the environs of Basra and Wasit since that time . ' Ujayf was successful in encircling the Zutt and forcing them to surrender after a seven @-@ month campaign , making a triumphal entry into Baghdad in January 835 with his numerous captives . Many of the Zutt were then sent to Ayn <unk> on the Byzantine frontier , where they fell fighting against the Byzantines .
The first major campaign of the new reign was directed against the Khurramites in Azerbaijan and Arran . The Khurramite revolt had been going on since 816 / 7 , aided by the inaccessible mountains of the province and the absence of large Arab Muslim population centres , except for a few cities in the lowlands . Al @-@ Ma 'mun had left the local Muslims largely to their own devices , although a succession of military commanders tried to subdue the rebellion on their own initiative , and thus gain control of the country 's newly discovered mineral resources , only to be defeated by the Khurramites under the capable leadership of Babak . Immediately after his accession , al @-@ Mu 'tasim sent the <unk> al @-@ <unk> of Baghdad and Samarra , Ishaq ibn Ibrahim ibn Mus 'ab , to deal with an expansion of the Khurramite rebellion from Jibal into Hamadan . Ishaq achieved success swiftly , and by December 833 had suppressed the rebellion , forcing many Khurramites to seek refuge in the Byzantine Empire . It was only in 835 that al @-@ Mu 'tasim took action against Babak when he assigned his trusted and capable lieutenant , Afshin , to command the campaign against him . After three years of cautious and methodical campaigning , Afshin was able to capture Babak at his capital of <unk> on 26 August 837 , extinguishing the rebellion . Babak was brought in triumph to Samarra , where he was executed .
The second major domestic campaign was against another autonomous ruler , Mazyar of the <unk> dynasty in Tabaristan . Tabaristan had been subdued in 760 , but Muslim presence was limited to the coastal lowlands of the Caspian Sea and their cities , while the mountainous areas remained under native rulers — chief among whom were the <unk> in the eastern and the <unk> in the central and western mountain ranges — who retained their autonomy in exchange for paying a tribute to the Caliphate . With the support of al @-@ Ma 'mun , Mazyar had established himself as the de facto ruler of all Tabaristan , even capturing the Muslim city of Amul and imprisoning the local Abbasid governor . Al @-@ Mu 'tasim confirmed him in his post on his accession , but trouble soon began when Mazyar refused to accept his subordination to the Tahirid viceroy of the east , Abdallah ibn Tahir , instead insisting on paying the taxes of his region directly to al @-@ Mu 'tasim 's agent . Tension mounted as the Tahirids encouraged the local Muslims to resist Mazyar , forcing the latter to adopt an increasingly confrontational stance against the Muslim settlers and turn for support on the native Iranian , and mostly Zoroastrian , peasantry , whom he encouraged to attack the Muslim landowners . Open conflict erupted in 838 , when his troops seized the cities of Amul and Sari , took the Muslim settlers prisoner , and executed many of them . The Tahirids in return invaded Tabaristan and in 839 captured Mazyar , who was betrayed by his brother <unk> . <unk> then succeeded his brother as a Tahirid appointee , while Mazyar was taken to Samarra , where he was flogged to death the next year . While the autonomy of the local dynasties was maintained in the aftermath of the revolt , the event marked the onset of the country 's rapid Islamization , including among the native dynasties .
Mazyar 's rebellion had important repercussions in Samarra . The <unk> 's intransigence had been secretly encouraged by Afshin , who hoped to discredit the Tahirids and assume their vast governorship in the east himself , but after the defeat of Mazyar , their correspondence was discovered . Already an exception among the <unk> elite due to his Iranian princely origins , and possibly suspect in the Caliph 's eyes due to the independent military following he commanded , this discovery served to discredit Afshin and provided the pretext for a show trial , where he was accused , among other things , of being a false Muslim , and of being accorded divine status by his subjects in his native <unk> . Afshin was found guilty and thrown into prison , where he was starved to death in 841 . Once more , the affair enhanced the standing of the Turkish leadership , who now received Afshin 's revenue and possessions . At about the same time , <unk> al @-@ <unk> , whom Afshin had appointed as governor of Adharbayjan after the defeat of the Khurramites , rose up in revolt , either because he had been involved in financial irregularities , or because he had been a co @-@ conspirator of Afshin 's . Bugha the Elder marched against him , forcing the rebel to capitulate and receive a safe @-@ passage for Samarra in 839 / 40 .
Near the end of al @-@ Mu 'tasim 's life there were a series of uprisings in the Syrian provinces , including the revolt by Abu Harb , known as al @-@ <unk> or " the Veiled One " , which brought to the fore the lingering pro @-@ Umayyad sentiment of a part of the Syrian Arabs .

Taking advantage of the Abbasids ' preoccupation with the suppression of the Khurramite rebellion , the Byzantine emperor Theophilos had launched a number of attacks on the Muslim frontier zone in the early 830s , and scored a few successes . His forces were also bolstered by some 14 @,@ 000 Khurramites who under their leader , Nasr , fled into the Empire , became baptized and enrolled into the Byzantine army under the command of Nasr , better known by his Christian name of Theophobos . In 837 , Theophilos , urged by the increasingly hard @-@ pressed Babak , launched a major campaign into the Muslim frontier lands , with an army reportedly numbering over 70 @,@ 000 men , whom he led in an almost unopposed invasion around the upper Euphrates . The Byzantines took the towns of <unk> ( Sozopetra ) and Arsamosata , ravaged and plundered the countryside , extracted ransom from Malatya and other cities in exchange for not attacking them , and defeated a number of smaller Arab forces . As refugees began arriving at Samarra , the caliphal court was outraged by the brutality and brazenness of the raids : not only had the Byzantines acted in open collusion with the Khurramites , but during the sack of <unk> all male prisoners were executed and the rest sold into slavery , and some captive women were raped by Theophilos ' Khurramites .
The Caliph took over preparations for a retaliatory expedition himself , as the campaigns against Byzantium were customarily the only ones where caliphs participated in person . Al @-@ Mu 'tasim assembled a huge force — 80 @,@ 000 men with 30 @,@ 000 servants and camp followers according to Michael the Syrian , or even bigger according to other writers — at Tarsus , and declared his target to be Amorium , the birthplace of the reigning Byzantine dynasty . The Caliph reportedly had the name painted on the shields and banners of his army . The campaign began in June , with a smaller force under Afshin attacking through the Pass of Hadath in the east , while the Caliph with the main army crossed the Cilician Gates on 19 – 21 June . Theophilos , who had been caught unaware by the two @-@ pronged Abbasid attack , tried to confront Afshin 's smaller force first , but suffered a major defeat at the Battle of Dazimon on 22 July , barely escaping with his life . Unable to offer any effective resistance to the Abbasid advance , the emperor returned to Constantinople . A week later , Afshin and the main caliphal army joined forces before Ancyra , which had been left defenceless and was plundered .
From Ancyra , the Abbasid army turned to Amorium , to which they laid siege on 1 August . The siege was fiercely contested , even after the Abbasids , informed by a defector , effected a breach in a weak spot of the wall . After two weeks , however , taking advantage of a short truce requested by the Byzantine commanders of the breach for negotiations , the Abbasid army stormed the city . The city was thoroughly plundered and its walls razed , while the populace , numbering into the tens of thousands , was carried off to be sold into slavery . According to al @-@ Tabari , al @-@ Mu 'tasim now pondered extending his campaign to attack Constantinople , when the conspiracy headed by his nephew , al @-@ Abbas , was uncovered . Al @-@ Mu 'tasim was forced to cut short his campaign and return quickly to his realm , without bothering with Theophilos and his forces , encamped in nearby Dorylaion . Taking the direct route from Amorium to the Cilician Gates , both the caliph 's army and its prisoners suffered in the march through the arid countryside of central Anatolia . Some captives were so exhausted that they could not move and were executed , whereupon others found the opportunity to escape . In retaliation , al @-@ Mu 'tasim , after separating the most prominent among them , executed the rest , some 6 @,@ 000 in number .
The sack of Amorium brought al @-@ Mu 'tasim much acclaim as a warrior @-@ caliph and <unk> , and was celebrated by contemporaries , most notably in Abu Tammam 's poems . The Abbasids , however , did not follow up on their success . Warfare continued between the two empires with raids and counter @-@ raids along the border , but after a few Byzantine successes a truce was agreed in 841 . At the time of his death in 842 , al @-@ Mu 'tasim was preparing yet another large @-@ scale invasion , but the great fleet he had prepared to assault Constantinople perished in a storm off Cape <unk> a few months later . Following al @-@ Mu 'tasim 's death , warfare gradually died down , and the Battle of Mauropotamos in 844 was the last major Arab – Byzantine engagement until the 850s .

Al @-@ Tabari states that al @-@ Mu 'tasim fell ill on 21 October 841 . His regular doctor , <unk> ibn <unk> , whom the Caliph had trusted implicitly , had died the previous year and the new physician Yahya ibn <unk> did not follow the normal treatment of cupping and purging , which according to Hunayn ibn Ishaq worsened the caliph 's illness and brought about his death on 5 January 842 , after a reign of eight years , eight months and two days according to the Islamic calendar . He was buried in the <unk> Palace in Samarra . He was succeeded by his son , al @-@ <unk> .
Al @-@ Tabari describes al @-@ Mu 'tasim as having a relatively easygoing nature , being kind , agreeable and charitable , while according to the Orientalist C.E. Bosworth , " Not much of [ al @-@ Mu 'tasim 's ] character emerges from the sources , though they stress his lack of culture compared with his brother al @-@ Ma 'mun , with his questing mind ; yet al @-@ Mu 'tasim 's qualities as a military commander seem assured , and the Abbasid caliphate remained under him a mighty political and military entity " .

The name al @-@ Mu 'tasim is also used for a fictional character in the story The Approach to al @-@ Mu 'tasim by Argentine author Jorge Luis Borges , which appears in his anthology <unk> . The al @-@ Mu 'tasim referenced there is not the Abbasid caliph , though Borges does state , regarding the original , non @-@ fictional al @-@ Mu 'tasim from whom the name is taken : " the name of that eighth Abbasid caliph who was victorious in eight battles , fathered eight sons and eight daughters , left eight thousand slaves , and ruled for a period of eight years , eight moons , and eight days " .
While not strictly accurate , Borges ' quote paraphrases al @-@ Tabari , who notes that he was " born in the eighth month , was the eighth caliph , in the eighth generation from al- ‘ Abbas , his lifespan was eight and forty years , that he died leaving eight sons and eight daughters , and that he reigned for eight years and eight months " , and reflects the widespread reference to al @-@ Mu 'tasim in the Arabic sources as al @-@ <unk> ( " the man of eight " ) .
