Who were the Fatimids?

The Fatimids were an Islamic dynasty that ruled a vast empire across North Africa and the Levant from the 10th to the 12th centuries. They claimed descent from Fatimah, the daughter of the Prophet Muhammad, and her husband Ali, the first Imam in Shia Islam, positioning themselves as leaders of the Shia Muslim community. The Fatimid Caliphate was known for its significant cultural, architectural, and scholarly contributions, particularly in cities like Cairo, which they founded in 969 CE. Their reign marked a period of prosperity and religious tolerance, although it eventually declined due to internal strife and external pressures.
