History of Russia
The war ended in 1721 when an exhausted Sweden sued for peace with Russia. Peter acquired four provinces situated south and east of the Gulf of Finland, thus securing his coveted access to the sea. There, in 1703, he had already founded the city that was to become Russia's new capital, Saint Petersburg, as a "window opened upon Europe" to replace Moscow, long Russia's cultural center. Russian intervention in the Commonwealth marked, with the Silent Sejm, the beginning of a 200-year domination of that region by the Russian Empire. In celebration of his conquests, Peter assumed the title of emperor, and the Russian Tsardom officially became the Russian Empire in 1721.
Russian Air Force
The Russian Air Force (, literally "military air forces of Russia") is a branch of the Russian Aerospace Forces, the latter being formed on 1 August 2015 with the merger of the Russian Air Force and the Russian Aerospace Defence Forces. The modern Russian Air Force was originally established on 7 May 1992 following Boris Yeltsin's creation of the Ministry of Defence; however, the Russian Federation's air force can trace its lineage and traditions back to the Imperial Russian Air Service (1912–1917) and the Soviet Air Forces (1918–1991).
