Hayyan he sold Zaragoza to Raymond of Pallars, but it was immediately retaken by the Emir and in 886 was given to the Banu Tujibi. In spite of a 17-year siege by the Banu Qasi, the Banu Tujibi continued to hold the city, growing in power and autonomy, until in 1018 they broke from Cordoban control and founded an independent Taifa state.
Taifa of Zaragoza
From 1018 to 1118 Zaragoza was one of the taifa kingdoms, independent Muslim states which emerged in the eleventh century following the destruction of the Cordoban Caliphate. During the first three decades of this period, 1018–1038, the city was ruled by theBanu Tujibi. In 1038 they were replaced by the Banu Hud, who had to deal with a complicated alliance with El Cid of Valencia and his Castilian masters against the Almoravids, who managed to bring the Taifas Emirates under their control. After the death of El Cid his kingdom was overrun by the Almoravids, who, by 1100, had managed to cross the Ebro into Barbastro, which brought Aragon into direct contact with them. The Banu Hud stubbornly resisted the Almoravids and ruled until they were eventually defeated by them in May 1110.
The last sultan of the Banu Hud, Abd-al-Malik Imad ad-Dawla, the last king of Zaragoza, forced to abandon his capital, allied himself with the Christian Aragonese under Alfonso the Battler and from that time the Muslims of Zaragoza became military regulars within the Aragonese forces.
Aragonese era
In 1118 the Aragonese conquered the city from the Almoravids and made it the capital of theKingdom of Aragon.

Zaragoza was the scene of two controversial martyrdoms related with the Spanish Inquisition:
