Another contemporary institution identified as Muslim, the Qarakhanid dynasty of the Kara-Khanid Khanate, operated much further east, established by Karluks who became Islamized after converting under Sultan Satuq Bughra Khan in the mid-10th century. However, the modern-day history of the Islamization of the region—or rather a conscious affiliation with Islam—dates to the reign of the ulus of the son of Genghis Khan, Jochi, who founded the Golden Horde, which operated from the 1240s to 1502. Kazakhs, Uzbeks and some Muslim populations of the Russian Federation trace their Islamic roots to the Golden Horde and while Berke Khan became the first Mongol monarch to adopt Islam officially and even to oppose his relative Hulagu Khan in the defense of Jerusalem at the Battle of Ain Jalut (1263), only much later did the change became pivotal when the Mongols converted en masse when a century later Uzbeg Khan (lived 1282–1341) converted - reportedly at the hands of the SufiSaint Baba Tukles.
