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.
Nicholas II of Russia
Russia was defeated in the 1904–1905 Russo-Japanese War, which saw the annihilation of the reinforcing Russian Baltic Fleet after being sent on its round-the-world cruise at the naval Battle of Tsushima, off the coasts of Korea and Japan, the loss of Russian influence over Manchuria and Korea, and the Japanese annexation to the north of South Sakhalin Island. The Anglo-Russian Entente was designed to counter the German Empire's attempts to gain influence in the Middle East, but it also ended the Great Game of confrontation between Russia and the United Kingdom. When all Russian diplomatic efforts to prevent the First World War (1914–1918) failed, Nicholas approved the Imperial Russian Army mobilization on 30 July 1914, which gave Imperial Germany formal grounds to declare war on Russia on 1 August 1914. An estimated 3.3 million Russians were killed in the First World War. The Imperial Russian Army's severe losses, the High Command's incompetent management of the war efforts, and lack of food and supplies on the home front were all leading causes of the fall of the House of Romanov.
