The Inca Civilization was a powerful empire that thrived in the Andean region of South America from the early 15th century until the Spanish conquest in the 16th century. Known for their advanced agricultural techniques, impressive architecture, and extensive road systems, the Incas created a vast network that connected their territories across modern-day Peru, Ecuador, and Chile. At the heart of the Inca Civilization was the city of Cusco, which served as the capital and a cultural hub. The Incas practiced a unique form of governance and religion, worshipping the sun god, Inti, and building monumental structures like Machu Picchu that still captivate visitors today.
