His son, Abbad II al-Mu'tadid (1042–1069) who succeeded him, expanded the taifa by conquering Mertola, Niebla, Saltés and Huelva, Silves, Santa María de Algarve during his reign.

The court felt insecure from Castile's military successes in Aragon, Valencia, and especially the fall of Toledo in 1085 under Alfonso VI.

[4] After they ravaged the city, al-Mu'tamid ordered his sons to surrender the royal fortress (the location of the present-day Alcázar of Seville).

[9] Jews were known to attain high governmental positions, like how the taifas of Granada and Seville both went to war under Jewish prime ministers.

Seville’s poetry largely focused on wine and eroticism, with poets who performed for their king being given the opportunity to earn riches and land.

Seville’s annexation of Córdoba in 1058 and academics fleeing from Toledo after Alfonso VI’s conquest of it in 1085, led to it having the reputation of being the pinnacle of al-Andalusian culture.

[11] A myriad of scientists are noted to have lived in Seville, like the astronomer al-Zarqali who created an improved astrolabe, and Ibn Bassal, an agronomist who tended to the royal gardens.

[16] The army size of the Taifas were recorded to be often small and so they relied on paying mercenaries and other Christian kings to support their military efforts.

[18] Along with monetary contributions, al-Mu'tamid would assist Alfonso VI by turning over his brother, Garcia, who was taking refuge in Seville.

[19] This alliance would not be strong, as al-Mu'tamid would fight against Alfonso VI with the Almoravids in the 1086 Battle of Sagrajas and later bargain for his support by offering his daughter-in-law to the Christian king in a marriage pact when Yusuf ibn Tashfin moved to conquer the taifa.
