Abu Muhammad ʿAbdallah 'al-ʿAdil' was an Almohad Caliph, a former governor in al-Andalus who challenged and secured the murder of his predecessor, Abd al-Wahid I. His 1224 coup ushered in a period of instability that lasted well beyond his own death in 1227. He is often regarded as one of the most disastrous of Almohad caliphs. His coup divided the Almohads and set in motion the loss of al-Andalus and the eventual collapse of the Almohad state.

The Almohad Caliphate or Almohad Empire was a North African Berber Muslim empire founded in the 12th century. At its height, it controlled much of the Iberian Peninsula (Al-Andalus) and North Africa.
