The 1033 Fez massacre was an event where, following their conquest of the city from the Maghrawa tribe, the forces of Abu'l Kamal Tamim, chief of the Banu Ifran tribe, perpetrated a massacre of Jews in Fes. David Corcos wrote that the Bani Ifran from near Salé attacked Fes, where they raped, pillaged, and killed 6,000 Jews.
