In 1545 the Wattasid ruler in northern Morocco, Abu Hassun, submitted to the Ottoman sultan and declared himself an Ottoman vassal, however the Ottomans were unable to intervene when the Wattasids had lost Fez to their southern Saadian rivals under their leader Mohammed ash-Sheikh. Ali Abu Hassun fled to the neighbouring Ottoman Empire possession of Algiers, where he was offered asylum.
