Abbad II al-Mu'tadid
Abu Amr Abbad II al-Mu'tadid (died February 28, 1069), a member of the Abbadid dynasty, was the second independent Muslim king of Seville (reigned 1042–1069) in Al-Andalus. His father, Abu al-Qasim Muhammad ibn Abbad, had established the taifa of Seville, and Abbad became its king when Abu al-Qasim died in 1042. He initially had amicable relations with his neighbour Ferdinand I, Count of Castile and King of León, and tolerated the Christian faith in his own lands. Among other acts of friendship, he authorized the transfer of Saint Isidore's relics from Seville to the Basilica of San Isidoro of León.
Al-Mu'tadid expanded his territory by conquering numerous Islamic taifas (independent principalities), including those of Mértola (1044–45), Huelva (1051), Algeciras (1055), Ronda (1065) and Arcos (1069). In 1053, he invited a number of minor Berber princes from the south to his palace in Seville, suffocating them to death by treating them to an open steam bath, having first sealed up all of the openings in the bathhouse. He also fought against the Zirids of Granada and the Aftasids of Badajoz, but with no conclusive results. In 1063, when Ferdinand I appeared with an army on the outskirts of Seville, Abbad was forced to acknowledge his suzerainty and to pay him tribute.
Abbad II al-Mu'tadid died in 1069 and was succeeded by his son, al-Mu'tamid ibn Abbad.
