The expansion of the Inca state, although it many cases the result of warfare, was also based on the implementation of agreements between the nobles in Cuzco and the rulers of each of the incorporated territories, as occurred in the Chilean northern and central territories at the end of the 15th century.

These political and cultural agreements can now be seen in the objects found in the tombs of the period, which were made with Inca shapes, but with the designs indigenous to each place. In this way, annexation to the Inca state did not mean the loss of cultural traditions.
