Criticism of monarchy has occurred since early medieval times. It can be targeted against the general form of government, monarchy, or more specifically, to particular monarchical governments as controlled by hereditary royal families. In some cases, this criticism, also known as anti-monarchism, can be curtailed by legal restrictions and be considered criminal speech, as in lèse-majesté.
Monarchies in Europe and their underlying concepts, such as the Divine Right of Kings, became increasingly criticized during the Age of Enlightenment, which notably paved the way to the French Revolution and the proclamation of the abolition of the monarchy in France. Earlier, the American Revolution saw the Patriots suppress the Loyalists and expelled all royal officials.
