The Andean Indians are a group of indigenous people who inhabit the Andes Mountains in South America. The most well-known of these tribes are the Incas, who were the largest and most powerful pre-Columbian civilization in the Americas. The Incas were known for their advanced engineering and agricultural techniques, as well as their impressive architecture. They were also renowned for their complex system of government and their religious beliefs. The Incas were eventually conquered by the Spanish in the 16th century, but their legacy still lives on in the culture and traditions of the Andean Indians.
