Georgios Papandreou was a Greek politician, the founder of the Papandreou political dynasty. He served three terms as prime minister of Greece. He was also deputy prime minister from 1950 to 1952, in the governments of Nikolaos Plastiras and Sofoklis Venizelos. He served numerous times as a cabinet minister, starting in 1923, in a political career that spanned more than five decades.

Nikolaos Plastiras was a Greek general and politician, who served twice as Prime Minister of Greece. A distinguished soldier known for his personal bravery, he became famous as "The Black Rider" during the Greco-Turkish War of 1919–1922, where he commanded the 5/42 Evzone Regiment. After the Greek defeat in the war, along with other Venizelist officers he launched the 11 September 1922 Revolution that deposed King Constantine I of Greece and his government. The military-led government ruled until January 1924, when power was handed over to an elected National Assembly, which later declared the Second Hellenic Republic. In the interwar period, Plastiras remained a devoted Venizelist and republican. Trying to avert the rise of the royalist People's Party and the restoration of the monarchy, he led two coup attempts in 1933 and 1935, both of which failed, forcing him to exile in France.
