Excerpts from Books and Wikipedia
"The war also saw the effective use of artillery by the Christians to rapidly conquer towns that would otherwise have required a long siege. On January 2, 1492 Muhammad XII of Granada (King Boabdil) surrendered the Emirate of Granada, the city of Granada, and the Alhambra palace to the Castilian forces. The war was a joint project between Isabella's Crown of Castile and Ferdinand's Crown of Aragon. The bulk of the troops and funds for the war came from Castile, and Granada was annexed into Castile's lands. The Crown of Aragon was less important: apart from the presence of King Ferdinand himself, Aragon provided naval collaboration, guns, and some financial loans. Aristocrats were offered the allure of new lands, while Ferdinand and Isabella centralized and consolidated power. The aftermath of the war saw the end of convivencia ("live and let live") between religions In the Iberian peninsula: the Jews were forced to convert to Christianity or be exiled in 1492, and by 1501, all of Granada's Muslims were obliged to either convert to Christianity, become slaves, or be exiled; by 1526 this prohibition spread to the rest of Spain."[Wikipedia] "Reconquista ends.
