History of Argentina

During the late 15th and early 16th centuries, the Inca Empire expanded to include the highlands of northwestern Argentina.12

Specifically, the province of Jujuy was part of the empire, and its historical Humahuaca Gorge served as a vital trade route connecting the region to Bolivia and Peru. The expansion into this area was largely carried out under the emperor Topa Inca Yupanqui, who brought most of the northwestern region under Inca control.31
