The Taifa of Mértola was a medieval Islamic Moorish taifa that existed in what is now southeastern Portugal. It existed during three distinct periods: from 1033 to 1044, from 1144 to 1145, and from 1146 to 1151. From 1044 until 1091 it was under the forcible control of the Taifa of Seville, by Abbad II al-Mu'tadid.[1] Its short-lived history ended in 1151, when it was finally conquered by the Almohad Caliphate.
