The Treaty of Granada, also known as the Surrender of Granada or the Capitulations, was signed and ratified on November 25, 1491, between Boabdil, the sultan of Granada, and Ferdinand and Isabella, the King and Queen of Castile, León, Aragon, and Sicily. It ended the Granada War, which had started in 1482 and culminated in the siege and battle of Granada, which began in spring 1491.
The Treaty of Granada was not merely a military surrender but the result of a decade of attrition known as the Granada War (1482-1492). The Nasrid Kingdom, the last vestige of Al-Andalus, was crippled by internal civil war between Sultan Boabdil (Muhammad XII) and his father and uncle.
Ferdinand and Isabella exploited this instability, capturing key cities like Malaga and Baza. By the time the siege of Granada began in the spring of 1491, the city was overcrowded with refugees and facing starvation. The treaty was negotiated in secret over several months to prevent a riot among the city's populace who were not yet ready to concede.

Initially, the Catholic conquerors implemented and reinforced the terms of the treaty. A joint municipal council was established in Granada, and the Muslims were allowed to elect their own representatives. Despite pressure from the Spanish clergy, Ferdinand chose a laissez-faire policy toward the Muslims, hoping interaction with Catholics would make them "understand the error" of their faith and abandon it. Hernando de Talavera, a friar of converso origins known for his moderation and piety, was appointed as the archbishop of Granada. He was known for his preference for preaching based on "Catholic reasoning", as opposed to "punishments and lashes". When Ferdinand and Isabella visited the city in the summer of 1499, they were greeted by an enthusiastic crowd, including Muslims.[1]
At the same time, Cardinal Francisco Jiménez de Cisneros, the archbishop of Toledo, arrived in Granada and began working alongside Talavera. Cisneros disliked Talavera's approach and began sending uncooperative Muslims, especially the noblemen, to prison, where they were treated harshly until they agreed to convert. Emboldened by the increase in conversions, Cisneros intensified the efforts, and on December 1499, he told Pope Alexander VI that three thousand Muslims converted in a single day. Cisneros's own church council warned that these methods might be a breach of the Treaty. The 16th-century hagiographer Álvar Gómez de Castro described the approach as "methods that were not correct".
In December 1499, amid the increasingly forced conversions and triggered by an incident involving an attempt by the authorities to reconvert a Muslim woman who had converted from Christianity, the population of Albayzín, the Muslim quarter of Granada, began an open and armed revolt. Talavera and Captain-General Tendilla resolved the situation by negotiating with the Muslims. Meanwhile, Cisneros was summoned to the court in Seville to account for his actions. He convinced the Catholic monarchs to issue a collective pardon to the rebels on the condition that they converted to Christianity. Consequently, the whole city of Granada nominally became Christian, and the treaty began to unravel.
The Treaty of Granada was not just the end of a war; it was the catalyst for a fundamental shift in world history. Its significance can be measured in three major ways:
Before 1492, Spain was a collection of diverse kingdoms with different laws and religions. The Treaty of Granada (and its subsequent violation) marked the moment Spain decided to become a unified nation-state with one religion (Catholicism) and one primary authority. This "Granada Model" where a state demands total cultural and religious uniformity from its citizens became the standard for European empires for the next several centuries.

The fall of Granada and the signing of the treaty were the final hurdles for the Spanish Crown's global ambitions.
For centuries, the Iberian Peninsula was defined by a period of coexistence, in which Muslims, Christians, and Jews lived in relatively close proximity, sharing scientific, medical, and philosophical knowledge. The Treaty of Granada was the final, flickering light of this era. By failing to uphold the treaty's promises of tolerance, the Spanish Crown signaled that the era of pluralism was over, replaced by the era of the Inquisition and religious "purity".
The treaty effectively removed the last Islamic "stronghold" in Western Europe. This shifted the focus of the conflict between Christian Europe and the Islamic world (specifically the Ottoman Empire) further east. It secured the Western Mediterranean for the Spanish and Portuguese, allowing them to turn their attention away from domestic defense and toward global expansion in African, Asia, and the Americas.
