In Greece, a coup d'état ends the Second Hellenic Republic.

A coup d'état, or simply a coup, is typically an illegal and overt attempt by a military organization or other government elites to unseat an incumbent 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.

The Second Hellenic Republic is a modern historiographical term used to refer to the Greek state during a period of republican governance between 1924 and 1935. To its contemporaries it was known officially as the Hellenic Republic or more commonly as Greece. It occupied virtually the coterminous territory of modern Greece and bordered Albania, Yugoslavia, Bulgaria, Turkey and the Italian Aegean Islands. The term Second Republic is used to differentiate it from the First and Third republics.
