Provocations and responses The truce of 1478 was still theoretically in effect when Granada launched a surprise attack against
Zahara on 26 December 1481, as part of a reprisal for a Christian raid. King Ferdinand formally took command at Alhama on 14 May 1482. The Christians next tried to besiege
Loja but failed to take the town. This setback was balanced by a twist that would prove to aid them greatly: on the same day that Loja was relieved, Abu Hasan's son, Abu Abdallah (also known as Boabdil), rebelled and styled himself
Emir Muhammad XI. The war continued into 1483. Abu Hasan's brother,
al-Zagal, defeated a large Christian raiding force in the hills of the
Axarquia east of
Málaga. However, at
Lucena the Christians were able to defeat and capture King Boabdil. Ferdinand and Isabella had previously not been intent on conquering all of Granada. With the capture of King Boabdil, however, Ferdinand decided to use him to conquer Granada entirely. In a letter written in August 1483, Ferdinand wrote "To put Granada in division and destroy it We have decided to free him.... He [Boabdil] has to make war on his father." Boabdil was obliged to flee to Ferdinand and Isabella's protection. The continuing division within the Muslim ranks and the cunning of the Marquis of Cádiz allowed the western reaches of Granada to be seized with unusual speed in 1485.
Ronda fell to him after fifteen days, thanks to his negotiations with the city's leaders. Ronda's fall allowed
Marbella, a base of the Granadan fleet, to come into Christian hands next.
Siege of Málaga Málaga, the chief seaport of Granada, was the main objective of the Castilian forces in 1487. Emir al-Zagal was slow to march to attempt to relieve the siege and was unable to harass the Christian armies safely because of the ongoing civil war; even after he left the city to come to the aid of Málaga, he was forced to leave troops in the Alhambra to defend against Boabdil and his followers. When the city finally fell, Ferdinand punished almost all the inhabitants for their stubborn resistance with slavery, while renegades were burned alive or pierced by reeds. The Jews of Malaga, however, were spared, as Castilian Jews ransomed them from slavery.
Siege of Baza Al-Zagal lost prestige from the fall of Málaga, and Boabdil took over all of the city of Granada in 1487; he additionally controlled the northeast of the country with
Vélez-Rubio,
Vélez-Blanco, and
Vera. Al-Zagal still controlled
Baza,
Guadix, and
Almería. Boabdil took no action as the Christian forces took some of his land, perhaps assuming it would shortly be returned to him. Baza was granted generous surrender terms, unlike Málaga.
Last stand at Granada palace in southern Spain With the fall of Baza and the capture of al-Zagal in 1490, it seemed as if the war was over; Ferdinand and Isabella believed this was the case. It was clear that such a position was untenable in the long term, so Boabdil sent out desperate requests for external aid.
Qaitbay, the
Sultan of Egypt mildly rebuked Ferdinand for the Granada War, but the
Mamluks that ruled Egypt were in a near constant war with the
Ottoman Turks. As Castile and Aragon were fellow enemies of the Turks, the Sultan had no desire to break their alliance against the Turks. Boabdil also requested aid from the
Sultanate of Fes, but no reply is recorded by history. North Africa continued to sell Castile wheat throughout the war and valued maintaining good trade relations. In any case, the Granadans no longer controlled any coastline from where to receive overseas aid. No help would be forthcoming for Granada. The reason for the long delay was not so much intransigence on either side, but rather the inability of the Granadan government to coordinate amongst itself in the midst of the disorder and tumult that gripped the city. After the terms, which proved rather generous to the local Muslim population, were negotiated, the city capitulated on January 2, 1492. The besieging Christians sneaked troops into the
Alhambra that day in case resistance materialized, which it did not. Granada's resistance had come to its end. ==Tactics and technology==
