The Incas were the founders of the city of Cuzco, which is located in modern-day Peru. They were a powerful and influential civilization that flourished in South America from the 13th to 16th centuries. The Incas were known for their advanced architecture, engineering, and agricultural techniques, as well as their complex social and political systems. They were also renowned for their art and culture, which included elaborate textiles, pottery, and metalwork. The Incas were eventually conquered by the Spanish in the 16th century, but their legacy lives on in the form of the ruins of their cities, which are still visited by tourists today.
