Almoravid policy in Spain had remained indecisive for two years, but it appears that the siege of Aledo in 1088 had convinced Yusuf ibn Tashufin of the urgent necessity of putting an end to the independent ta'ifa kingdoms if he is going to rescue Spanish Islam.

From 1090 onward, he deposes their rulers, beginning with those of the “New” Berber ta'ifas of Granada—then, in 1091, of the Arab ta'ifas of Almería and Seville, and, in 1093 of Badajoz, a stronghold of the “Andalusians” (Arabs, Berbers who had settled in Al-Andalus a long time earlier, and the population that had converted to Islam).

Granada's Jewish community, believed to have sided with the Christians, is destroyed.

Many flee, penniless, for Christian Toledo.
