History
The Pica culture flourished during the Late Intermediate period, also known as the Regional Development period. Building on routes established through their relations with the Tiwanaku Empire in the previous period, the Pica culture developed major trade routes that allowed them to maintain ties with the San Pedro de Atacama and Altiplano Meridional (southern Altiplano) cultures, and even with groups as far away as northwest Argentina. They were later subsumed by the Inka Empire.
