The Spanish Empire was one of the largest empires in history, spanning from the late 15th century to the early 19th century. It began with the voyages of explorers like Christopher Columbus, who discovered the Americas in 1492. The empire expanded rapidly, claiming vast territories in North America, South America, and parts of Asia and Africa. At its height, the Spanish Empire was known for its wealth, driven by resources like gold and silver from its colonies. It played a significant role in global trade and cultural exchange, influencing languages, religions, and societies across the world. The empire began to decline in the 17th century, facing challenges from rival powers and internal issues.
