November 17 Polytechnic uprising
It's April 1967. In Greece, a group of colonels overthrows the government.
In 1973, six years later, an uprising takes place. It was as a massive student demonstration of popular rejection of the military junta and its main centre was the Athens Polytechnic (Πολυτεχνείο).
It's November 17th. A tank eventually crashes through the gates of the university, ending the uprising in bloodshed leaving several dead and injured.
Less than a year later, on 24 July 1974, and under the pressure of the Turkish invasion of Cyprus, the junta's rule ends leading to democracy and the establishment of the Third Hellenic Republic.
Until now, November 17 is marked as a holiday in Greece for all educational establishments and marches usually take place in the centre of major cities such as Athens and Thessaloniki.
Due to the pandemic, in 2020 the public commemoration and gatherings were prohibited. Unfortunately, several people, including political parties, defied the orders of the police leading to riots in Athens and other cities.
