ابن تومرت
Ibn Tumart himself died in 1130, well before the Almohads' main military successes, and had no spiritual successor. However, the political leadership of his movement passed on to Abd al-Mu'min, who effectively founded the ruling Almohad dynasty. He and his successors had very different personalities from Ibn Tumart but nonetheless pursued his reforms, culminating in a particularly aggressive push by Ya'qub al-Mansur (who arguably ruled at the apogee of Almohad power in the late 13th century).
