Prime Minister of Greece Ioannis Metaxas suspends parliament and the Constitution and establishes the 4th of August Regime.
The 4th of August Regime (Greek: 4 , romanized: Kathests tis tetrtis Avgostou), commonly also known as the Metaxas regime ( , Kathests Metax), was a totalitarian regime under the leadership of General Ioannis Metaxas that ruled the Kingdom of Greece from 1936 to 1941. On 4 August 1936, Metaxas, with the support of King George II, suspended the Greek parliament and went on to preside over a conservative, staunchly anti-communist government. The regime took inspiration in its symbolism and rhetoric from Fascist Italy, but retained close links to Britain and the French Third Republic, rather than the Axis powers. Lacking a popular base, after Metaxas' death in January 1941 the regime hinged entirely on the King. Although Greece was occupied following the German invasion of Greece in April 1941 and the Greek government was forced into exile in the British-controlled Kingdom of Egypt, several prominent figures of the regime, notably the notorious security chief Konstantinos Maniadakis, survived for several months in cabinet until the King was forced to dismiss them in a compromise with the representatives of the old democratic political establishment.
This is a list of the heads of government of the modern Greek state, from its establishment during the Greek Revolution to the present day. Although various official and semi-official appellations were used during the early decades of independent statehood, the title of prime minister has been the formal designation of the office at least since 1843. On dates, Greece officially adopted the Gregorian calendar on 16 February 1923 (which became 1 March). All dates prior to that, unless specifically denoted, are Old Style.
