Fatima Al-Fihri emigrated from present-day Tunisia to Fez, Morocco with her family in the early 9th century. Fatima and her sister Mariam were well-educated and wealthy women who wanted to use their wealth for the benefit of their community. In 859 CE, Fatima established the Al-Qarawiyyin Mosque and the University of Al-Qarawiyyin, the oldest university in the world. The University became a premier institution for the study of both religious and secular sciences. By the 14th century, the university had 8,000 students, and was attended by many notable scholars and scientists including the likes of al-Hasan ibn Muhammad al-Wazzan (Leo Africanus), Ibn Khaldun and Jewish scholar Maimonides.
