monarchomaque

The Monarchomachs were originally French Huguenot theorists who opposed monarchy at the end of the 16th century, known in particular for having theoretically justified tyrannicide. The term was originally a pejorative word coined in 1600 by the Scottish royalist and Catholic William Barclay (1548–1608) from the Greek μόναρχος (monarchos "monarch, sole ruler") and μάχομαι ("makhomai" the verb meaning "to fight"), meaning "those who fight against monarchs."
