Narva is a municipality and city in Estonia. It is located in Ida-Viru county, at the eastern extreme point of Estonia, on the west bank of the Narva river which forms the Estonia–Russia international border. With 54,409 inhabitants (as of 2020) Narva is Estonia's third largest city after capital Tallinn and Tartu. In 1944, Narva was nearly completely destroyed during the battles of World War II. During the period of Soviet occupation (1944–1991), the city’s original native inhabitants were not permitted to return after the war, and immigrant workers from Russia and other parts of the former USSR were brought in to populate the city. The city whose population had been, as of 1934 census, 65% ethnic Estonian, became overwhelmingly non-Estonian in the second half of the 20th century. According to more recent data, 46.7% of the city's inhabitants are citizens of Estonia, 36.3% are citizens of the Russian Federation, while 15.3% of the population has undefined citizenship.
