Which term refers to the adaptation of indigenous practices under the influence of outside powers?

The appropriate term for the adaptation of indigenous practices under the influence of outside powers is acculturation. This concept specifically describes the process through which individuals and groups from one culture come into contact with another culture, resulting in changes to their cultural practices, beliefs, and social structures. Acculturation often occurs when a dominant group exerts influence on a subordinate group, which may lead to the incorporation of elements from the dominant culture into the indigenous culture while still retaining aspects of their original practices.

Indigenization, although it may seem relevant, usually refers to the process by which outside influences are integrated into local contexts in a way that is meaningful and adapted to the indigenous culture. It suggests a more active and creative process of transformation rather than a passive adaptation.

Assimilation implies a more complete integration where the indigenous culture is absorbed and loses its distinctiveness in the face of a dominant culture. This process often entails the loss or significant alteration of the original cultural identity.

Cultural blend signifies a combination of elements from different cultures, but it does not specifically address the influence of outside powers on indigenous practices as captured in the concept of acculturation.
