Lithuanization
Lithuanization (sometimes also called the Lithuanianization) is a process of cultural assimilation - adoption, either forced or voluntary, of Lithuanian culture or language, experienced by non-Lithuanian people or groups of people.
History
In the early Middle Ages the consolidation of Baltic lands by the Duchy of Lithuania led to the gradual Lithuanization and subsequent assimilation of neighbouring Baltic tribes or their parts, including the Selonians, Jotvingians, Nadruvians and Curonians who shared religious, cultural, and linguistic similarities with the Lithuanians.
