The Taifa of Seville was an Arab kingdom which was ruled by the Abbadid dynasty. It was established in 1023 and lasted until 1091, in what is today southern Spain and Portugal. It gained independence from the Caliphate of Cordoba and it expanded the territory it ruled in the mid-11th century. The emerging power of Castile led Seville to ask military assistance from the Almoravids, who then occupied Seville.
