Kalb, Kinda, Ghassanids, and Lakhmids. Since the 1834 Peasants' revolt in Palestine, the Arabic-speaking population of Palestine has shed its formerly tribal structure and emerged as the Palestinians. Native Jordanians are either descended from Bedouins (of which, 6% live a nomadic lifestyle), or from the many deeply rooted non bedouin communities across the country, most notably Al-Salt city west of Amman which was at the time of Emirate the largest urban settlement east of the Jordan River. Along with indigenous communities in Al Husn, Aqaba, Irbid, Al Karak, Madaba, Jerash, Ajloun, Fuheis and Pella. In Jordan, there is no official census data for how many inhabitants have Palestinian roots but they are estimated to constitute half of the population, which in 2008 amounted to about 3 million. Palestinian Central Bureau of Statistics put their number at 3.24 million in 2009. The Bedouins of western Egypt and eastern Libya are traditionally divided into Saʿada and Murabtin, the Saʿada having higher social status. This may derive from a historical feudal system in which the Murabtin were vassals to the Saʿada. In Sudan, there are numerous Arabic-speaking tribes, including the Shaigya, Ja'alin and Shukria, who are ancestrally related to the Nubians. These groups are collectively known as Sudanese Arabs. In addition, there are other Afroasiatic-speaking populations, such as Copts and Beja. The medieval trans-Saharan slave trade in the Sudan drove a wedge between the Arabized Sudanese and the non-Arabized Nilotic Sudanese populations. It has contributed to ethnic conflict in the region, such as the Sudanese conflict in South Kordofan and Blue Nile, Northern Mali conflict, or the Boko Haram insurgency. The Arabs of the Maghreb are descendants of Arabian tribes of Banu Hilal, the Banu Sulaym and the Maqil native of Middle East and of other tribes native to Saudi Arabia, Yemen and Iraq. Arabs and Arabic-speakers inhabit plains and cities. The Banu Hilal spent almost a century in Egypt before moving to Libya, Tunisia and Algeria, and another century later some moved to Morocco, it is logical to think that they are mixed with inhabitants of Egypt and with Libya. Demographics The total number of Arabic speakers living in the Arab nations is estimated at 366 million by the CIA Factbook (as of 2014). The estimated number of Arabs in countries outside the Arab League is estimated at 17.5 million, yielding a total of close to 384 million. Arab world According to
