Government or rule by opposition to anarchism; a system of organized authority and control designed to prevent anarchic chaos.
From 'anti-' (against) + 'anarchy' (lack of government). A descriptive term for any system of rule structured against anarchist principles.
While 'anarchy' means no government, 'antarchy' would be the opposite—heavy government—which shows how one political word can have a mirror image with the opposite meaning!
