A Constitutional Monarchy is a system of government in which governmental power is exercised on behalf of a, usually hereditary, royal head-of-state. The monarch, or a representative of the monarch - ie, a viceroy, such as a governor general - generally exercises only ceremonial powers, transferring authority to successive elected politicians, but holding reserve powers to dissolve the government when requested by parliament or in dire circumstances. Constitutional monarchies are almost always parliamentary systems, where ministerial offices are evolved from medieval court advisers.
Cascadian monarchism may indicate a desire to join Cascadia into the British Commonwealth, with the British (Canadian) royal family as sovereign. Cascadian monarchism may also be a movement to create a distinct Cascadian royal family, either by adopting a cadet branch of an existing royal family, or establishing a royal line independent of already existing royal lineages.
