Abu al Qasim Muhammad ibn Abbad

Abu al-Qasim Muhammad ibn Abbad (or Abbad I; 984 – 25 January 1042) was the eponymous founder of the Abbadid dynasty; he was the first independent Muslim ruler of Seville in Al-Andalus (ruled 1023–1042),dying in 1042.

The qadi (religious judge) Abu al-Qasim Muhammad ibn Abbad was named governor of Seville by caliph Yahya ibn Ali ibn Hammud al-Mu'tali in 1023. However, with the Caliphate of Cordoba losing integrity, the Abbadids, a Sevillan family of Arabic origins, seized control.

As a result, later in 1023, Abu al-Qasim Muhammad ibn Abbad declared the Taifa of Seville independent from Córdoban rule, establishing the taifa of Seville.
