Who are monarchs enemies?

Monarchs' enemies can vary greatly depending on the historical and political context, but they often include rival factions, rebellious nobles, or other nations seeking power or territory. In some cases, discontented subjects or revolutionary movements may arise as opposition to monarchic rule. Additionally, ideological adversaries—such as republicans or revolutionaries advocating for democratic governance—can pose significant threats to monarchies. Ultimately, the nature of these enemies is shaped by the specific circumstances and challenges faced by each monarch.
