Mitma
Mitma was a policy of forced resettlement employed by the Incas. It involved the forceful migration of groups of extended families or ethnic groups from their home territory to lands recently conquered by the Incas. The objective was to transfer both loyalty to the state and a cultural baggage of Inca culture such as language, technology, economic and other resources into areas that were in transition.
This policy moved entire communities hundreds of kilometers to create enclaves of settlers called mitmaqkuna. This policy was used over a long period of time in all border regions of the empire.
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.
The strategic and political use of this policy might have also been related to transhumance, when large herds of llamas, alpacas and vicuñas were managed by the state. The element of political stability is obvious as the new settlements depended on the Incas for defense, supplies and governance.
