The Quechua ethnic group is one of the largest indigenous populations in South America, primarily found in Peru, Bolivia, Ecuador, and Colombia. They are known for their rich cultural heritage, including traditional music, dance, and textiles. The Quechua language, also called Quechua, is still widely spoken among the community. Historically, the Quechua people were part of the Inca Empire, which was the largest empire in pre-Columbian America. Today, they continue to practice agriculture, often cultivating crops like potatoes and maize, while also maintaining their customs and beliefs in a rapidly changing world.
