The Abbadid dynasty or Abbadids () was an Arab dynasty from the tribe of Banu Lakhm of al-Hirah, which ruled the Taifa of Seville in al-Andalus following the fall of the Caliphate of Cordoba in 1031. After the collapse, they were the most powerful Taifa and before long absorbed most of the others. Abbadid rule lasted from about 1023 until 1091,
Overview
During their reign, the Abbadids also made significant contributions to the development of science, military technology and medicine. Their patronage of scholars and researchers helped to create a culture of learning that encouraged scientific inquiry and experimentation. The Abbadids' interest in science is evident in the many scientific works that were written during their reign, including the famous Book of Optics by the polymath Ibn al-Haytham.
In addition to their patronage of the arts, sciences, and literature, the Abbadids also made significant contributions to the development of Islamic law and jurisprudence. They were known for their fair and just rule, and they encouraged the use of Islamic law to settle disputes and conflicts. This helped to create a stable and peaceful society in Andalusia, which was admired by people throughout the Muslim world.
Despite their many achievements, the Abbadids were eventually overthrown by the Almoravids, who were more conservative and orthodox in their interpretation of Islam. The Almoravids saw the Abbadids' tolerance of other religions and cultures as a threat to the purity of Islam, and they were determined to impose their own strict interpretation of the faith on Andalusia. This led to a period of religious and cultural repression that stifled the creative and intellectual energy of the region.
Despite their eventual downfall, the Abbadids left a lasting legacy in Andalusia. They were known for their love of art and architecture, their patronage of literature and science, and their tolerance of other religions and cultures. Their reign helped to create a rich and diverse society that was admired throughout the Muslim world, and their contributions to Islamic law and jurisprudence helped to create a stable and just society in Andalusia. The Abbadids' legacy continues to be celebrated today as an important period in the history of the Iberian Peninsula.
History
Abu al-Qasim Muhammad ibn Abbad (ruled 1023–1042)
Abu al-Qasim Muhammad ibn Abbad (), the qadi of Seville, founded the house in 1023. Initially, he refused the position, worried of the fatal repercussions that could follow failure or the changing of the voice of the people. At first, he professed to rule only with the advice of a council formed of the nobles. Before the military could become a formidable force, a Berber army from Málaga was at the gates demanding entrance and fealty, in the form of sons of the richest and most powerful nobles and merchants as hostages. Abu al-Qasim, to show his people his trust in the situation, offered his own son as solitary collateral. This show of bravery, convinced his population to follow him with near zeal, and at this time dismissed the council and began his solitary rule.
From this point on, he was able to make small inroads into the small principalities surrounding him. This began with an alliance forged with the governor of Carmona. His first conquest was Beja, followed by the plunder and subsequent control of the coastal regions from Cádiz west. At this time, it was apparent to Abu al-Qasim that a coalition was needed to defeat the growing Berber threat; however it was also apparent that he would not be accepted as the head of this coalition of caliphates. Abu al-Qasim was able to procure an imposter who resembled the caliph Hisham II. This man, who was a mat-maker by trade, had previously been involved in an unsuccessful attempt at trickery. This time the deception was successful and the coalition formed starting with Cordoba, then followed by Dénia, Balearic Islands, Tortosa, and Valencia. Angered by the growing forces against him, Yahya was lured into an ambush and along with the larger portion of his command killed. When Abu al-Qasim died in 1042 he had created a state which, though weak in itself, appeared strong as compared to its neighbours. He had made his family the recognized leaders of the Andalusian Muslims against the neo-Berber element arrayed under the king of Granada.
He habitually preserved the skulls of the enemies he had killed—those of the meaner men to be used as flower-pots, while those of the princes were kept in special chests. He devoted his reign mainly to extending his power at the expense of his smaller neighbours, and in conflicts with his chief rival the king of Granada. These incessant wars weakened the Muslims, to the great advantage of the rising power of the Christian kings of León and Castile, but they gave the kingdom of Seville a certain superiority over the other little states. After 1063 he was assailed by Fernando El Magno of Castile and León, who marched to the gates of Seville, and forced him to pay tribute.
Muhammad al-Mu'tamid (ruled 1069–1095)

The son of Abbad II, Muhammad al-Mu'tamid (1069–1095) — who reigned under the title al-Mu'tamid — was the third and last of the Abbadids.
With the assistance of the Almoravids, they were able to defeat Alfonso in 1086. During the six years which preceded his deposition in 1091, Abbasid behaved with valour on the field, but was politically inept and cruel. At the end what he had foreseen happened to him: in 1095 his kingdom was overthrown by Yusuf ibn Tashfin and Almoravid sympathizers within his city, following which he was deposed. She is said by Iberian Muslim sources to have been the daughter-in-law of Al Mutamid, the Muslim King of Seville, wife of his son Abu al Fatah al Ma'Mun, Emir of Cordoba, (d. 1091). Later Iberian Christian chroniclers call her Al Mutamid's daughter, but the Islamic chroniclers are considered more reliable. With the fall of Seville to the Almoravids, she fled to the protection of Alfonso VI of Castile, becoming his mistress, converting to Christianity and taking the baptismal name of Isabel.
