Forced assimilation is an involuntary process of cultural assimilation of religious or ethnic minority groups during which they are forced to adopt language, identity, norms, mores, customs, traditions, values, mentality, perceptions, way of life, and often religion and ideology of established and generally larger community belonging to dominant culture by government. Also enforcement of a new language in legislation, education, literature, worshiping counts as forced assimilation. Unlike ethnic cleansing, the local population is not outright destroyed and may or may not be forced to leave a certain area. Instead the population becomes assimilated by force. It has often been used after an area has changed nationality, often in the aftermath of war. Some examples are both the German and French forced assimilation in the provinces Alsace and Lorraine, and some decades after the Swedish conquests of the Danish provinces Scania, Blekinge and Halland the local population was submitted to forced assimilation, or even the forced assimilation of ethnic Teochews in Bangkok by the Siam government during World War I until the 1973 uprising.
