Spyridon "Spyros" Markezinis was a Greek politician, longtime member of the Hellenic Parliament, and briefly the Prime Minister of Greece during the aborted attempt at metapolitefsi (democratization) of the Greek military regime in 1973.

Georgios Papadopoulos was a Greek military officer and dictator who led a coup d'etat in Greece in 1967 and became the country's Prime Minister from 1967 to 1973. He also was the President of Greece under the junta in 1973, following a referendum. However, after the effective suppression of the Athens Polytechnic uprising, he was, in turn, overthrown by hardliner Dimitrios Ioannidis, in a string of events that would culminate to the fall of the regime in 1974. His and the dictatorship's legacy, as well as its methods he constructed and effects on Greek economy and society as a whole, are still fiercely debated.
