The Caliphate is one of the high points of Islam, and at the time Muslim civilization, together with that of Byzantium, China and India, was the most developed part of the world. It was ruled by the Abbasid dynasty of caliphs, who built their capital in Baghdad after overthrowing the Umayyad caliphs from all but Al Andalus. It was built by the descendant of Muhammad's youngest uncle, Abbas ibn Abd al-Muttalib. It was created in Harran in 750 C.E. and shifted its capital in 762 C.E from Harran to Baghdad. It flourished for two centuries, but slowly went into decline with the rise to power of the Turkish army it had created, the Mamluks. Within 150 years of gaining power across Persia, they were forced to cede power to local dynastic amirs who only nominally acknowledged their power, and had to cede Al Andalus to an escaped Umayyad royal and the Maghreb and Ifriqiya to independent entities such as the Aghlabids and the Fatimids. Their rule was ended in 1258, when Hulagu Khan, the Mongol conqueror, sacked Baghdad. While they continued to claim authority in religious matters from their base in Mamluk Egypt, the dynasty's secular authority had ended. Descendants of the Abbasids include the al-Abbasi tribe who live northeast of Tikrit in modern-day Iraq.
