It was divided into the Crown of Castile, the Crown of Aragon, the Kingdom of Navarre, the Kingdom of Portugal, and the Islamic Kingdom of Granada.

Unification of Castile and Aragon: Dates and Circumstances

How did the kingdoms of Castile and Aragon unite?

In 1469, Ferdinand, son of the King of Aragon, and Isabella, sister of the King of Castile, were married. In 1479, Ferdinand succeeded his father on the throne of Aragon. This led to a union, but it was initially a personal union only. Each kingdom maintained its own laws and institutions. The death of Isabella in 1504 jeopardized this dynastic union.

Final Unification of the Peninsular Kingdoms

How and by whom were the peninsular kingdoms finally united?

They were united under Charles, son of Juana la Loca (Joanna the Mad). The Castilian throne passed to Juana, daughter of Isabella, while Ferdinand remained King of Aragon. Juana’s madness rendered her unfit to rule, and Ferdinand eventually exercised the regency until Charles I, Juana’s son, ascended to the throne of both crowns in 1516.

Strategies of the Catholic Monarchs for Crown Unification

How did the Catholic Monarchs consolidate their power?

They created the Holy Brotherhood (Santa Hermandad) in Castile, a police unit dedicated to fighting bandits and resisting the demands of the nobility. They also reorganized the justice system and strengthened the Chancery (Chancillería), the highest judicial body. The Catholic Monarchs appointed magistrates (corregidores), officials who enforced the authority of the kings within the municipalities of Castile. They strengthened the royal treasury by seizing privileges and lands previously granted to the nobility.

Territorial Conquests During the Reign of the Catholic Monarchs

What lands were conquered during their reign?

In 1504, they incorporated the Kingdom of Naples, and conquered Melilla and Oran in Africa. In the Atlantic, they took control of the Canary Islands and began the conquest of America.

Religious Unity Under the Catholic Monarchs

How did the Catholic Monarchs achieve religious unity?

They established the Court of the Inquisition in 1478 to persecute heretics. The court had jurisdiction throughout Castile and Aragon and was known for its harsh sentences. They expelled the Jews in 1492, issuing a royal decree that all Jews must convert to Christianity or leave Spain. In 1512, a similar decree mandated the conversion or expulsion of Muslims. The Muslims who did not convert were called Moriscos.
