courtiers pressured him to abdicate and become a monk, Isaac initiated many useful reforms. The dynasty returned to the throne with the accession of Alexios I Komnenos, Isaac I's nephew, in 1081. By this time, descendants of all the previous dynasties of Byzantium seem to have disappeared from the realm, such as the important Scleros and Argyros families. Descendants of those emperors lived abroad, having married into the royal families of Georgia, Russia, France, Persia, Italy, Germany, Poland, Bulgaria, Hungary and Serbia; this made it easier for the Komnenos family to ascend to the throne. Upon their rise to the throne, the Komnenoi became intermarried with the previous Doukas dynasty: Alexios I married Irene Doukaina, the grandniece of Constantine X Doukas, who had succeeded Isaac I in 1059. Thereafter the combined clan was often referred to as Komnenodoukai () and several individuals used both surnames together. Several families descended from this wider clan, such as Palaiologos, Angelos, Vatatzes and Laskaris. Alexios and Irene's youngest daughter Theodora ensured the future success of the Angelos family by marrying into it: Theodora's grandsons became the emperors Isaac II Angelos (reigned 1185–1195 and 1203–1204) and Alexios III Angelos (reigned 1195-1203). Komnenoi as emperors Under Alexios I and his successors the Empire was fairly prosperous and stable. Alexios moved the imperial palace to the Blachernae section of Constantinople. Much of Anatolia was recovered from the Seljuk Turks, who had captured it just prior to Alexios' reign. Alexios also saw the First Crusade pass through Byzantine territory, leading to the establishment of the Crusader states in the east. The Komnenos dynasty was very much involved in crusader affairs, and also intermarried with the reigning families of the Principality of Antioch and the Kingdom of Jerusalem - Theodora Komnene, niece of Manuel I Komnenos, married Baldwin III of Jerusalem, and Maria, grandniece of Manuel, married Amalric I of Jerusalem. Remarkably, Alexios ruled for 37 years, and his son John II ruled for 25, after uncovering a conspiracy against him by his sister, the chronicler Anna Komnene. John's son Manuel ruled for another 37 years. The Komnenos dynasty produced a number of branches. As imperial succession was not in a determined order but rather depended on personal power and the wishes of one's predecessor, within a few generations several relatives were able to present themselves as claimants. After Manuel I's reign the Komnenos dynasty fell into conspiracies and
