It was proclaimed by the European Parliament on 23 September 2008. Its aim is to commemorate the victims of mass deportation and extermination, as well as to promote democracy, peace and stability in Europe. The first formal commemoration of this day was organised in 2011 in Warsaw, under the auspices of the Polish Presidency. Meeting participants approved a document entitled „Warsaw Declaration for the European Day of Remembrance for the Victims of Totalitarian Regimes”. The declaration states that crimes of totalitarian regimes in Europe should be acknowledged and condemned, regardless of their type and ideology.
The official celebrations of the European Day of Remembrance for Victims of Totalitarian Regimes in 2018 will take place in Estonia. However, it will also be celebrated in a number of European cities. The Study Centre for National Reconciliation in cooperation with military vicariate and the parish of St. Nicholas prepare celebrations in Ljubljana.
