The Russo-Japanese War of 1904–1905 arose from competing imperial ambitions in Manchuria and Korea. Japan's military victories over Russia, including the destruction of the Russian fleet at Tsushima, left both powers willing to seek a negotiated settlement, with Japan facing financial exhaustion and Russia beset by internal unrest.
Negotiations mediated by U.S. President Theodore Roosevelt took place at the Portsmouth Naval Shipyard in Kittery, Maine, from August 6 to 30, 1905. Delegates from Japan and Russia agreed to terms, and the treaty was formally signed on September 5, 1905, concluding one of the first major conflicts of the twentieth century.
The treaty recognized Japan's dominant position in Korea, which became a Japanese protectorate shortly afterward, and transferred Russia's lease on the Liaodong Peninsula, the South Manchuria Railway, and southern Sakhalin to Japan. Roosevelt was awarded the Nobel Peace Prize for his mediation, the first American to receive that honor.
