The Treaty of Portsmouth is a treaty that formally ended the 1904–1905 Russo-Japanese War. It was signed on September 5, 1905,[1] after negotiations from August 6 to 30, at the Portsmouth Naval Shipyard in Kittery, Maine, United States. U.S. President Theodore Roosevelt was instrumental in the negotiations and won the Nobel Peace Prize for his efforts, the first ever American recipient. The treaty recognized Japan's hegemony in Korea (which soon after became a protectorate of the Empire of Japan), awarded it Russia's lease on the Liaodong Peninsula (which became the Kwantung Leased Territory), control of the Russian-built South Manchuria Railway, and the southern half of the island of Sakhalin (Karafuto).
