Athens Polytechnic Uprising

The Athens Polytechnic uprising in 1973 was a massive demonstration of popular rejection of the Greek military junta of 1967–1974. The uprising began on November 14, 1973, escalated to an open anti-junta revolt and ended in bloodshed in the early morning of November 17 after a series of events starting with a tank crashing through the gates of the Polytechnic.

Since April 21, 1967, Greece had been under the dictatorial rule of the military, a regime which abolished civil rights, dissolved political parties and exiled, imprisoned and tortured politicians and citizens based on their political beliefs.

1973 found the military junta leader Georgios Papadopoulos having undertaken a "liberalisation" process of the regime, which included the release of political prisoners and the partial lifting of censorship, as well as promises of a new constitution and new elections for a return to civilian rule. Opposition elements including Socialists were thus given the opportunity to undertake political action against the junta.

United States took a clandestine interest in suppressing Socialists and had a C.I.A. operative named John Maury who was in consultation supporting the Junta Leaders. Republican President Richard Nixon's Vice President Spiros Anaganostopolous (Spiro Agnew) praised the junta as "the best thing to happen to Greece since Pericles ruled in ancient Athens".

The junta, trying to control every aspect of politics, had interfered with student syndicalism since 1967, by banning student elections in universities, forcibly drafting students and imposing non-elected student union leaders in the national student's union, EFEE. These actions eventually created anti-junta sentiments among students, such as geology student Kostas Georgakis who committed suicide in 1970 in Genoa, Italy as an act of protest against the junta. With that exception, the first massive public action against the junta came from students on February 21, 1973.
