A person who believes in and actively promotes opposition to monarchy as a form of government.
From antimonarchism + -ist (a suffix indicating a person who practices or advocates). This term names individuals who actively work against monarchical systems.
Some of history's most famous antimonarchists were born into privilege—like the Marquis de Lafayette or even some European nobles—which shows that opposition to monarchy was ideological rather than just coming from people who lacked power.
