Crowned republic
A crowned republic, also known as a monarchical republic, is a system of monarchy where the monarch's role is almost entirely ceremonial and where nearly all of the royal prerogatives are exercised in such a way that the monarch personally has little power over executive and constitutional issues. The term "crowned republic" has been used by a small number of authors (below) to informally describe governments such as Australia and the United Kingdom, although these countries are usually classed as constitutional monarchies.
