The Transportation Over Lake Titicaca

According to legend, the Uru descend from a people that spoke the Puquina language. However, while most of the Uru have shifted to Aymara and Spanish. The Uru considered themselves the owners of the lake and water. According to the legend, Uru used to say that they had black blood, because they did not feel the cold. They historically called themselves Lupihaques, "sons of the Sun". Although the Uru language is nearly extinct, the Uru continue to maintain their identity and some old customs.

The purpose of the island settlements was originally defensive; if a threat arose the floating islands could be moved. The largest island retains a watchtower, as do most smaller islands.

The Uru traded with the Aymara tribe on the mainland, intermarrying with them and eventually abandoning the Uru language for that of the Aymara. About 500 years ago they lost their original language. When conquered by the Inca empire, they had to pay taxes to them, and often were made slaves.
