A political ideology or movement that opposes monarchy as a system of government.
From antimonarch + -ism (a suffix indicating a movement or ideology). This term emerged in political discourse as organized movements against monarchical rule developed.
Antimonarchism as a formal ideology is interesting because it's defined as much by what it opposes as by what it supports—different antimonarchist movements wanted republics, democracies, or revolutions, but they all agreed monarchies were wrong.
