today western european countries have what form of government
Europe The political map of Europe is substantially derived from the re-organisation of Europe following the Napoleonic Wars in 1815. The prevalent form of government in Europe is parliamentary democracy, in most cases in the form of Republic; in 1815, the prevalent form of government was still the Monarchy. Europe's remaining eleven monarchies[190] are constitutional.
Central government A central government is the government of a nation-state and is a characteristic of a unitary state. This is the same thing as a federal government which may have distinct powers at various levels authorized or delegated to it by its member states, though the adjective 'central' is sometimes used to describe it.[1] The structure of central governments varies. Many countries have created autonomous regions by delegating powers from the central government to governments at a subnational level, such as a regional, state or local level. Based on a broad definition of a basic political system, there are two or more levels of government that exist within an established territory and govern through common institutions with overlapping or shared powers as prescribed by a constitution or other law.
