Modern anthropological and linguistic studies suggest that about a quarter to a third of the population of the empire was resettled and is probably the largest single element of the Inca domination.
[4] The strategic and political use of this policy might have also been related to transhumancy, when large herds of llamas, alpacas and vicuñas were managed by the state.
[5] The mitma policy was one method that involved planned transfers of entire populations to regions that were less developed or had a high degree of rebellions or uprisings.
[10] Once in their new settlement places, the mitmas participants received land to plant crops and raise livestock, as well as to build houses.
[12] In addition, the Inca kept resettled elites in check by promoting them to bureaucratic positions in order to keep them dependent on imperial systems and ideologies for their own prestige and status.
[14] These policies allowed the state to monitor the movement of its subjects, and officials could easily determine who belonged in a particular region and who was not supposed to be there.
[17] After imposing rule over their neighbors, the Incas seized an opportunity to intervene in the internal affairs of those living further south in the Urubamba Valley and the Titicaca Basin.
[19] In addition to the Titicaca Basin, the Inca forces went north and stormed Cajamarca, capturing it and leaving a small garrison there.
[22] It is thought that the existence of "Chilean" placenames such as Loa, Calama, and Erqui (Elqui) in southern Bolivia reflect Inca population transfers.
