The Prague uprising (Czech: Pražské povstání) was a partially successful attempt by the Czech resistance movement to liberate the city of Prague from German occupation in May 1945, during the end of World War II. The preceding six years of occupation had fuelled anti-German sentiment and the rapid advance of Allied forces from the Red Army and the United States Army offered the resistance a chance of success. On 5 May 1945, during the end of World War II in Europe, occupying German forces in Bohemia and Moravia were spontaneously attacked by civilians in an uprising, with Czech resistance leaders emerging from hiding to join them. The Russian Liberation Army (ROA), a collaborationist formation of ethnic Russians, defected and supported the insurgents.
