Superstate
A
superstate is an agglomeration of nations and/or states, often linguistically and ethnically diverse, under a single political-administrative structure. This is distinct from the concept of superpower, although these are frequently seen together. It is also distinct from the concept of empire, where one nation dominates other nations through military, political, and economic power, as in the Roman Empire, although an empire may also be a superstate, as in ancient Persia, Russian Empire, India and China. An example of a small superstate would be the republic of Yugoslavia before its breakup at the end of the cold war. An example of an ancient superstate would be China, under various dynasties. Eurosceptics argue that the European Union is a current example of an emerging superstate. Multinational states such as Canada and the Russian Federation are not considered superstates. The former Soviet Union, though being constitutionally defined as union of republics, was
de facto a superstate due to a major cultural and linguistical diversity between its inhabited ethnicities, never really identified themselves as the single Soviet nation despite the official doctrine.
