The Almohad Caliphate or Almohad Empire was a North African Muslim empire ruled by a Berber dynasty from 1130 to 1269, which at its height controlled much of the Maghreb and the Iberian Peninsula (Al-Andalus). The Spanish name "Almohads" derives from the Arabic al-Muwaḥḥidūn, "those who espouse Oneness", reflecting the dynasty's emphasis on divine unity and its protest against what it regarded as the lax character of prevailing Islam, particularly under the Almoravids.
