For religious reasons that Granada was invaded in 1482, Ferdinand and Isabella invaded Granada for religious reasons as Catholic faith wanted to be a faith of everyone. But this is not the only reason for conquest. There are certainly other factors that will play a role in the decision, and then the actual conquest of Granada. Isabella is a very devout Catholic, she hopes that the religion of her country is unified and hopes to transform them all into Catholic faith by taking over Granada. I want to fight for the glory of God.
When Queen Isabella and King Ferdinand gave attention to the Kingdom of Granada, Granada has been ruled by Muslim Moors since the Spanish invasion of the 8th century. Protected by the natural barriers and protected towns, Granada endured the attempts to rebuild the Moors immediately after the invasion and occupation. However, contrary to the solid leadership of Isabella and Ferdinand, Granada's split leadership in the late 15th century was disproportionate. Isabella and Ferdinand conquered Granada for 10 years and won the last victory in 1492. In the last reconquest, the Spaniard occupied Boadil, one of the rulers. After paying the ransom, he was released and allowed back to Granada to resume his domination.
At the end of the conquest, only Granada left Isabella and Ferdinand for conquest. The Emirate of Granada has been dominated by the Muslim Nasrid dynasty since the middle of the 13th century. It is protected by natural barriers and a defensive town and endured the long rebuilding process. On February 1, 1482, the king and queen arrived at Medina del Campo, which is usually considered the beginning of the Granada war. Participation of Isabella and Ferdinand in the war was clear from the beginning, but the leadership of Granada has been divided and it was never possible to propose a unified front. However, it took ten years to conquer Granada and finally reached its peak in 1492.
The monarch began a series of campaigns called the Granada war (1482 - 1492). It was awarded by Sheps IV by enormous income and enforcement of Crusade Tax to enable monarchs to fund war. After the decade's battle, the Granada war ended in 1492. At that time, Emile Bohadiel handed the key to the Castilian soldiers to the Alhambra in Granada. Along with the collapse of Granada in January 1492, Isabella and Ferdinand pursued a further policy of unity of religion, the expulsion of Jews who refused to convert to Christianity in particular.
