Stylianos Gonatas (Greek: Στυλιανός Γονατάς; 15 August 1876[1] – 29 March 1966) was an officer of the Hellenic Army, Venizelist politician, and Prime Minister of Greece from 1922 to 1924.

In Greece, this disaster led to a political crisis, and military revolts broke out in September amongst the evacuated troops in Thessaloniki, Chios and Lesbos, headed primarily by Venizelist officers.

The army contingents in Lesbos formed a Revolutionary Committee headed by Colonel Gonatas, which dispatched by airplane the following demands to Athens: the dismissal of the government, the dissolution of Parliament, the holding of new elections, and the abdication of King Constantine in favour of the Diadoch, Prince George.

The first cabinet formed under the regime of the Revolutionary Committee (which had established itself as the real master of Greece with King George II merely as a figurehead) underwent several slight changes, the chief of which was caused by the refusal of Zaimis to retain the premiership (which remained vacant, with Sotirios Krokidas as acting premier), and after having been in power for less than two months resigned on 24 November, chiefly owing to internal differences arising from the Trial of the Six (ex-ministers, statesmen, and military leaders tried by a revolutionary tribunal on the charges of high treason).

Colonel Gonatas was appointed premier, and Konstantinos Rentis, one of the leaders of the republican group, as acting minister for foreign affairs (see 1922 Government Crisis).

He never sought public office again; continuing only to serve as former Prime Ministers did on the Crown Council advising the King until his death on March 29, 1966, in Athens.
