Siege of Leningrad in the context of "World War II casualties of the Soviet Union"

Saint Petersburg, formerly known as Petrograd and later Leningrad, is the second-largest city in Russia after Moscow. It is situated on the River Neva, at the head of the Gulf of Finland on the Baltic Sea. With an area of 1,439 sq km (556 sq mi), Saint Petersburg is the smallest administrative division of Russia by area. The city had a population of 5,601,911 residents as of 2021, with more than 6.4 million people living in the metropolitan area. Saint Petersburg is the fourth-most populous city in Europe, the most populous city on the Baltic Sea, and the world's northernmost city of more than 1 million residents. As the former capital of the Russian Empire, and a historically strategic port, it is governed as a federal city.

The city was founded by Tsar Peter the Great on 27 May 1703 on the site of a captured Swedish fortress, and was named after the apostle Saint Peter. In Russia, Saint Petersburg is historically and culturally associated with the birth of the Russian Empire and Russia's entry into modern history as a European great power. It served as a capital of the Tsardom of Russia, and the subsequent Russian Empire, from 1712 to 1918 (being replaced by Moscow for a short period between 1728 and 1730). After the October Revolution in 1917, the Bolsheviks moved their government to Moscow. The city was renamed Leningrad after Lenin's death in 1924. It was the site of the siege of Leningrad during World War II, the most lethal siege in history. In June 1991, only a few months before the Belovezha Accords and the dissolution of the Soviet Union, voters in a city-wide referendum supported restoring the city's original name.

Military production during World War II was the production or mobilization of arms, ammunition, personnel and financing by the belligerents of the war, from the occupation of Austria in early 1938 to the surrender and occupation of Japan in late 1945.

The mobilization of funds, people, natural resources and material for the production and supply of military equipment and military forces during World War II was a critical component of the war effort. During the conflict, the Allies outpaced the Axis powers in most production categories. Access to the funding and industrial resources necessary to sustain the war effort was linked to their respective economic and political alliances.

The Neva (/ˈniːvə/ NEE-və, UK also /ˈneɪvə/ NAY-və; Russian: Нева́, IPA: [nʲɪˈva] ) is a river in northwestern Russia flowing from Lake Ladoga through the western part of Leningrad Oblast (historical region of Ingria) to the Neva Bay of the Gulf of Finland. Despite its modest length of 74 kilometres (46 mi), it is the fourth-largest river in Europe in terms of average discharge (after the Volga, the Danube and the Rhine).

The Neva is the only river flowing from Lake Ladoga. It flows through the city of Saint Petersburg, the three smaller towns of Shlisselburg, Kirovsk and Otradnoye, and dozens of settlements. It is navigable throughout and is part of the Volga–Baltic Waterway and White Sea–Baltic Canal. It is the site of many major historical events, including the Battle of the Neva in 1240 which gave Alexander Nevsky his name, the founding of Saint Petersburg in 1703, and the Siege of Leningrad by the German army during World War II. The river played a vital role in trade between Byzantium and Scandinavia.

Starvation of a civilian population is a war crime, a crime against humanity, and/or an act of genocide according to modern international criminal law. Starvation has not always been illegal according to international law; the starvation of civilians during the siege of Leningrad was ruled to be not criminal by a United States military court, and the 1949 Geneva Convention, though imposing limits, "accepted the legality of starvation as a weapon of war in principle". Historically, the development of laws against starvation has been hampered by the Western powers who wish to use blockades against their enemies; however, it was banned in 1977 by Protocol I and Protocol II to the Geneva Conventions and criminalized by the Rome Statute. Prosecutions for starvation have been rare.
