Jabarkan Kronologi dari Perang Granada dalam bahasa melayu

The truce of 1478 was still theoretically in effect when Granada launched a surprise attack against Zahara in December 1481, as part of a reprisal for a Christian raid.  The town fell, and the population was enslaved. This attack proved to be a great provocation, and factions in favor of war in Andalusia used it to rally support for a counterstrike, quickly moving to take credit for it, and backed a wider war.  The seizure of Alhama and its subsequent royal endorsement is usually said to be the formal beginning of the Granada War. Abu Hasan attempted to retake Alhama by siege in March, but was unsuccessful. Reinforcements from the rest of Castile and Aragon averted the possibility of retaking Alhama in April 1482; King Ferdinand himself formally took command at Alhama on May 14, 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 as Loja was relieved, Abu Hasan's son, Abu Abdallah or Boabdil, rebelled and styled himself Emir Muhammad XII. 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 II and Isabella I 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 of 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." With Boabdil's release, now as a pseudo-Christian ally, the Granadan civil war would continue. A Granadan chronicler commented that Boabdil's capture was "the cause of the fatherland's destruction."

In 1485, the fortunes of the Granadan internal conflict shifted yet again. Boabdil was expelled from the Albayzín, his base of power, by Hasan's brother al-Zagal. Al-Zagal also took command of the nation itself, dethroning his aging brother, who died shortly thereafter. 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 a mere 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.

Tidak lama kemudian Boabdil dibebaskan daripada perlindungan Kristian untuk menyambung tugas beliau memerintah Granada. Untuk tiga tahun seterusnya, beliau bertindak sebagai de facto vassal di bawahh Ferdinand dan Isabella. Beliau dijanjikan kemerdekaan terhad untuk Granada dan perdamaian dengan penduduk Kristian; daripada Monarki Katolik, beliau memegang gelaran Duke untuk mana-mana kota yang beliau boleh mengawal.
