Multinational state
Appearance
A multinational state is a state in which the population consists of two or more ethnically distinct nations that are of significant size. This contrasts with a nation-state where a single nation comprises the bulk of the population.
Examples include
Multinational states differ from states like Japan, Poland or the Koreas in which an overwhelming majority of the population is ethnically homogeneous.
Empires may be dominated by one particular nation, sometimes organized as a nation-state. For example, the Austro-Hungarian Empire, which consisted of Austrian Germans, Magyars (Hungarians), Czechs, Romanians, Slovenes, Poles, Croats, Serbians, and Italians.
