ابن تومرت
Abu Zakariya would again rebel against central authority after he heard that the Almohad caliph in Marrakesh al-Ma'mun, had overthrown and killed two of his brothers and that he cancelled the creed of Ibn Tumart. Additionally, al-Ma'mun instructed the Imams to insult Ibn Tumart in the mosques and cancelled the call to prayer in Berber.
