World War II (1941–1945)

During World War II, German forces besieged Leningrad following the Axis invasion of the Soviet Union in June 1941. The siege lasted 872 days, or almost two and a half years, from 8 September 1941 to 27 January 1944.

The Siege of Leningrad proved one of the longest, most destructive, and most lethal sieges of a major city in modern history. It isolated the city from food supplies except those provided through the Road of Life across Lake Ladoga, which could not make it through until the lake froze. More than one million civilians were killed, mainly from starvation. There were incidents of cannibalism, with around 2,000 residents arrested for eating other people. Many others escaped or were evacuated, so the city became largely depopulated.

On 1 May 1945 Joseph Stalin, in his Supreme Commander Order No. 20, named Leningrad, alongside Stalingrad, Sevastopol, and Odesa, hero cities of the war. A law acknowledging the honorary title of "Hero City" passed on 8 May 1965 (the 20th anniversary of the victory in the Great Patriotic War), during the Brezhnev era. The Presidium of the Supreme Soviet of the USSR awarded Leningrad as a Hero City the Order of Lenin and the Gold Star medal "for the heroic resistance of the city and tenacity of the survivors of the Siege". The Hero-City Obelisk bearing the Gold Star sign was installed in April 1985.
