Historical map showing the region of the Crown of Castile in Spain.

The Crown of Castile was a medieval polity in the Iberian Peninsula that formed in 1230. It began when King Ferdinand III united the kingdoms of Castile and León. This union created a strong and important region in Spain.

In 1492, a very important event happened for Castile. That year, Christopher Columbus sailed and discovered the Americas. This opened up new lands for Spain and changed the world forever. Castile also played a big role in exploring and conquering many places, including the Aztec Empire, the Inca Empire, and the Philippines. These adventures helped Castile become a powerful global empire during the 16th century.

Even after Castile joined with Aragon in 1469, the title "King of Castile" was still used by rulers like Charles I. But in the early 1700s, changes were made that brought Castile and Aragon even closer together. These changes helped form the country we now know as Spain.

History

The Crown of Castile began as a union of two kingdoms, León and Castile, in the year 1230. This happened when Ferdinand III, who was the king of Castile, also became king of León. This union created a stronger kingdom in the middle of the Iberian Peninsula.

Over time, the Crown of Castile grew larger. It took over more lands, including parts of what is now southern Spain. In 1469, the crowns of Castile and Aragon were joined together when Isabella I of Castile married Ferdinand II of Aragon. This marriage helped bring more unity to Spain.

One of the most important events was in 1492, when Christopher Columbus sailed west and discovered new lands. This began Spain’s role in exploring and ruling parts of the world, changing history forever. The leaders of Castile and Aragon worked together to support these voyages and manage the new territories they found.

The Crown in late medieval Spain

The Crown of Castile was made up of several regions and kingdoms that came together under one rule. These areas included parts of modern-day Spain, such as Castile-León, Castile-La Mancha, and Extremadura. Each of these regions kept some of their own traditions and laws, but they were all governed by the same king.

Over time, the lands of the Crown of Castile grew through battles and agreements with neighboring areas. This brought many different cultures and people together under one kingdom, shaping the history and culture of the Iberian Peninsula.
