A person or force opposed to emperors or imperial rule; one who resists or opposes imperial authority.
From anti- (against) + emperor (from Latin imperator, military commander). This is a modern construction combining a prefix with a historical title.
Throughout history, antiemperors could be anyone from revolutionary leaders to philosophical thinkers who rejected the very idea of absolute imperial power—like the Stoics who questioned whether any single person should rule absolutely.
