Georgios Papadopoulos

Geórgios Papadopoulos (/ˌpæpəˈdɒpələs/;[1][2] Greek: Γεώργιος Παπαδόπουλος [ʝeˈorʝi.os papaˈðopulos]; 5 May 1919 – 27 June 1999) was a Greek military officer and dictator who was the President of Greece under the junta in 1973, following a referendum. He joined the Royal Hellenic Army during the Second World War and resisted the Greco-Italian War; in so doing he obtained honors and became a hero. He remained in the army after the war and rose to the rank of colonel.

In April 1967, Papadopoulos and a group of other mid-level army officers overthrew the democratic government and established a military junta that lasted until 1974. Assuming dictatorial powers, he led an authoritarian, anti-communist and ultranationalist regime which eventually ended the Greek monarchy and established a republic, with himself as president. In 1973, he was overthrown and arrested by his co-conspirator Brigadier General Dimitrios Ioannidis. After the Metapolitefsi which restored democracy in 1974, Papadopoulos was tried for his part in the crimes of the junta and sentenced to death, but his sentence was commuted to life imprisonment. Refusing several offers of clemency in exchange for admitting guilt for the crimes of the junta, he spent the remainder of his life in prison.
