Parliamentarization
Under parliamentary refers historically to power change process in the 19th and 20th century by the absolutist monarchy to constitutional democracy with legislative parliaments , determined by free popular elections mostly in a multiparty system.
In terms of constitutional law, a democracy or a constitutional monarchy is parliamentarized if it is not the head of state or the monarch but the parliament that determines the government; H. on or off. A constitutional monarchy can therefore be parliamentarized or not parliamentarized. A constitutional monarchy is not “parliamentarized” simply because it has a parliament. It depends on whether this parliament determines the government and whether this government is accountable to parliament. If a constitutional monarchy is not parliamentarized (e.g. the German Empire), the monarch determines and appoints the government, which theoretically does not have to be supported by a parliamentary majority and which is responsible to the monarch and not to parliament.
Most of today's European monarchies are parliamentary monarchies (with the exception of Liechtenstein ).
