What parts did the Arab Caliphate split into?

The Arab caliphate was weakened by popular uprisings against feudal lords and dominion. Large feudal lords were strengthening at that time. This led to the collapse of the Caliphate. By the middle of the 8th century, an Arab state was formed in Spain. The eastern Arab possessions went to the Baghdad Caliphate, of which Baghdad became the capital. In the 9th century, the separation of Egypt, Central Asia, Iran and Afghanistan took place. In Asia, the Turks conquered the main part of the possessions, and the Baghdad Caliph had only Mesopotamia in subjection.
