Underground, Moscow, Russia

In January 1905, the institution of the City Governor, or Mayor, was officially introduced in Moscow, and Alexander Adrianov became Moscow’s first official mayor. Following the Russian Revolution of 1917, on 12 March 1918 Moscow became the capital of the Russian Soviet Federative Socialist Republic and of the Soviet Union less than five years later. During World War II (the period from June 22, 1941, to May 9, 1945 known in Russia as the Great Patriotic War), after the German invasion of the USSR, the Soviet State Defense Committee and the General Staff of the Red Army was located in Moscow.
In 1941, sixteen divisions of the national volunteers (more than 160,000 people), twenty-five battalions (18,500 people) and four engineering regiments were formed among the Muscovites. That November, the German Army Group Center was stopped at the outskirts of the city and then driven off in the Battle of Moscow. Many factories were evacuated, together with much of the government, and from 20 October the city was declared to be under siege. Its remaining inhabitants built and manned antitank defenses, while the city was bombarded from the air. Joseph Stalin refused to leave the city, meaning the general staff and the council of people's commissars remained in the city as well. Despite the siege and the bombings, the construction of Moscow's metro system continued through the war, and by the end of the war several new metro lines were opened.
Both German and Soviet casualties during the battle of Moscow have been a subject of debate, as various sources provide somewhat different estimates. Therefore, total casualties between 30 September 1941, and 7 January 1942, are estimated to be between 248,000 and 400,000 for the Wehrmacht and between 650,000 and 1,280,000 for the Red Army.
On 1 May 1944, a medal For the defense of Moscow and in 1947 another medal In memory of the 800th anniversary of Moscow were instituted. In commemoration of the 20th anniversary of the victory over Nazi Germany, on May 8, 1965, Moscow became one of twelve Soviet cities awarded the title of Hero City.
