Coup d'état
A coup d'état ( , koo-day-TAH; French: [ku deta] ; lit. 'stroke of state'), or simply a coup (, KOO), is typically an illegal and overt attempt by a military organization or other government elites to unseat an incumbent person or leadership. A self-coup is said to take place when a leader, having come to power through legal means, tries to stay in power through illegal means.
