Abu Bakr ibn Umar

Abu Bakr ibn Umar ibn Ibrahim ibn Turgut, sometimes suffixed al-Sanhaji or al-Lamtuni (died 1087; Arabic: أبو بكر بن عمر اللمتوني, romanized: Abū Bakr ibn 'Umar al Lamtūnī) was a chieftain of the Lamtuna Berber Tribe and Amir of the Almoravids from 1056 until his death. He is credited to have founded the Moroccan city of Marrakesh, and under his rule the heretic Barghawatas were destroyed. His campaigns may have included attacking the Ghana Empire, although the Almoravid impact on and relationship with sub-Saharan states is disputed amongst historians. In November of 1087, Abu Bakr died of a poisoned arrow in what is now Mauritania.
