伊本·图马特
When Ibn Tumart died in 1130 at his ribat in Tinmel, after suffering a severe defeat at the hands of the Almoravids, Abd al-Mu'min and the council of ten kept the death of Ibn Tumart secret for 3 years, since the Almohads were going through a difficult time in their fight against the Almoravids. He also feared that the Masmuda (the Berber tribe of Ibn Tumart) would not accept him as their leader since he was an outsider. He did eventually lead the Almohads when a family relationship was arranged between him and Cheikh Abu Hafs, the leader of the Masmuda. He then came forward as the lieutenant of Ibn Tumart, became the leader of the movement, and forged it into a powerful military force. Under him, the Almohads swept down from the mountains, eventually destroying the power of the faltering Almoravid dynasty by 1147.
