Originally, it was called al-Manṣūriyyah, and was erected northeast of Fustat by order of Fatmid general Al-Qaid Jawhar ibn Abdallah. The construction of a new settlement took about four years, after which it became the new capital of the Fatmid Caliphate. After caliph Al-Mu’izz visited the city, he changed its name to Qāhirat al-Mu’izz. It is where the current name—Cairo—derives from. The Fatmid dynasty descended from the son of Fatma—Muhammad’s daughter—and ruled Egypt until mid-September, 1171.
