When did the Incas come from?

The Incas originated in the Andean region of South America, specifically in the area around modern-day Cusco, Peru. They began as a small tribe in the early 15th century and rapidly expanded their empire, ultimately establishing the largest empire in pre-Columbian America by the mid-16th century. The Inca civilization reached its peak under the leadership of Emperor Pachacuti in the 15th century, before the Spanish conquest in the 1530s.
