Lake Titicaca has played an important role in the history of Peru. The first inhabitants of Lake Titicaca and its surrounding areas were the Puraka people, which populated the area around the 2nd century. Afterwards, tribes such as the Aymara and the Colla people occupied the region, until they were absorbed into the Inca Empire. The descendants of these native populations, the Uros people, currently live on the Lake Titicaca. They have preserved their traditions and live on giant totora rafts built on the surface of the lake.
