How were the beginnings of the almoravid and almohad empires similar?

The beginnings of the Almoravid and Almohad empires were marked by their roots in religious reform and a desire to unify the Muslim community in North Africa and al-Andalus. Both empires emerged as responses to perceived moral decay and a need for stricter adherence to Islamic principles. The Almoravids, founded in the 11th century, focused on promoting a puritanical interpretation of Islam, while the Almohads, emerging in the 12th century, followed a similar path but with an emphasis on a more philosophical approach to the faith. Both movements gained significant support through their military conquests and the establishment of strong centralized rule.
