Athens Polytechnic Uprising -- November 17 1973
It was 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. 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. (wiki)
Basically, 52 years ago, people of my country, but mostly university students, protested against the dictatorship and junta that my country had. They fought bravely, and many of them gave their lives for the future of our country. If not for that, Greeks today might still not have had freedom of speech, democracy and many other things.
The message I want to send with this, is that EVERY PROTEST MATTERS. EVERY VOICE MATTERS. FIGHT FOR YOUR RIGHTS, YOUR FREEDOM, AND EQUALITY.
