The Almohads overthrow the Almoravids by conquering Marrakesh. They institute puritanical policies throughout their domains in North Africa and Spain. Ibn Bassam — whose compendium, Al-Dhakira, is a valuable historical source — dies in Santarem. His death occurs a few years after the demise of Judah Halevi, an eminent Andalusi Jewish philosopher and poet, who left Spain for the Holy Land.
