On the run from the Almohads, the Rambam's family ultimately settled in Fostat, Egypt, where the Karaites dominated the Jewish community. The Karaites rejected the Oral Torah and forbade the use of medical doctors, a philosophy that was both spiritually and physically destroying the Jewish people. Armed with his Torah scholarship and knowledge of medicine, the Rambam fought to re-educate the Jews and wrote the great body of work that eradicated the Karaite and Islamic influences.
