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.
Politics of Poland The Government of Poland takes place in the framework of a unitary semi-presidential representative democratic republic,[1][2][3][4] whereby the President is the head of state and the Prime Minister is the head of government.
