The Athens Polytechnic uprising, a massive demonstration of popular rejection of the Greek military junta of 1967–74, begins.

The Athens Polytechnic uprising occurred in November 1973 as a massive student demonstration of popular rejection of the Greek military junta of 1967–1974. It began on 14 November 1973, escalated to an open anti-junta revolt, and ended in bloodshed in the early morning of 17 November after a series of events starting with a tank crashing through the gates of the Athens Polytechnic. It is believed that approximately 40 people were killed by the Greek army on that day, and more than 2,000 were injured. This was the first event in a series of political crises that ultimately led to the fall of the junta in the summer of 1974, just a few months later.

The Greek junta or Regime of the Colonels was a right-wing military junta that ruled Greece from 1967 to 1974. On 21 April 1967, a group of colonels overthrew the caretaker government a month before scheduled elections which Georgios Papandreou's Centre Union was favoured to win.
