The Treaty of Portsmouth ended the war. It was signed on September 5, 1905, after negotiations from August 6 to August 30, at the Portsmouth Naval Shipyard in Kittery, Maine, United States (at the time considered part of Portsmouth, New Hampshire, however). U.S. President Theodore Roosevelt was instrumental in the negotiations and won the Nobel Peace Prize for his efforts.
