National Independence Day (Polish: Narodowe Święto Niepodległości) is a national day in Poland celebrated on 11 November to commemorate the anniversary of the restoration of Poland’s sovereignty as the Second Polish Republic in 1918, after 123 years of partition by the Russian Empire, the Kingdom of Prussia and the Habsburg Empire. It is a non-working day in Poland.
On 11th November every year patriots(NOT NAZI), ultras groups, hooligan groups and many other people gather in Warszawa. Almost every year there is trouble with pro-russian people who go on the celebration and provoke the nationalists. Lots of pyro and polish songs accompany the march.
