Resistance Fighting Day also known as Otto Tief Government Day is a national holiday in Estonia which takes on 22 September. It honors the Estonian commander Otto Tief's attempt to restore Estonian independence in 1944. The holiday is a date of remembrance, commemorating the victims of the subsequent re-establishment of Soviet rule in Estonia following the Nazi rule, and the resulting sovietisation of the republic from 1944 to 1950. It falls under the cultural symbols designed to recognize the Occupation of the Baltic states until 1991. It was known in the former Estonian SSR, as well as today by the Russian Federation and pro-Russian forces in Estonia as the Day of the Liberation of Tallinn from Nazi Invaders, celebrating the Soviet Tallinn Offensive by the Red Army's 2nd Shock and 8th Armies and the Baltic Fleet against the Wehrmacht.
