What is "deculturalization"

Deculturalization is the process by which an ethnic group is forced to abandon its language, culture, and customs. It is the destruction of the culture of a dominated group and its replacement by the culture of the dominating group. Deculturalization is a slow process due to its extensive goal of fully replacing the subordinate ethnic group's culture, language, and customs. This term is often confused with Assimilation (sociology) and Acculturation.
