The Day of Dignity and Freedom is marked in Ukraine on November 21 every year.
Euromaidan demonstrations started in Kyiv after the decision of President Victor Yanukovych to suspend the preparation for signing the Association Agreement on November 21, 2013. All at once, this announcement resulted in the largest protests since the last Orange Revolution in 2004.
The Day of Dignity and Freedom is a public holiday established by President Poroshenko in 2014.
The Association Agreement between Ukraine and the EU should have been signed at a summit meeting of Eastern Partnership in Vilnius held through November 28-29, 2013. However, on November 21, the Ukrainian government decided to stop the preparation for signing the Association Agreement. On the same day, late at night, people started gathering at Maidan Nezalezhnosti in Kyiv to protest against this government's decision.
November 21, 2013, is officially considered the beginning of the Ukrainian Revolution of Dignity. Around 2,000 people gathered the same night when the decree to change the geopolitical course of Ukraine and suspend preparations for signing the Association Agreement was made public.
Many opposition leaders called for protest via Facebook and Twitter and later on the representatives of the opposition and pro-EU parties were the ones to lead the protests.
Later, the protests turned from pro-European to anti-governmental and became more large-scale. On February 18-20, 2014, the most tragic days of the Revolution of Dignity happened. The clashes took place in downtown Kyiv, the Trade Unions Building was set on fire; snipers killed over 70 Euromaidan activists who became the Heroes of Heavenly Hundred.
Within the celebration of the Day of Dignity and Freedom, the memorial, solemn, cultural, and mass events are held in cities all over Ukraine. These events aim to honor the memory of the partakers of the Revolution of Dignity, who defended the European choice of Ukraine and strived for the democratic development of the country.
