September 5, 1905: Theodore Roosevelt Negotiates a Peaceful Settlement of the Russo-Japanese War
On this day in 1905, peace delegates in New Hampshire signed the Treaty of Portsmouth which officially ended the Russo-Japanese War, a conflict over control of Manchuria and Korea. The Japanese emerged victorious as the first non-Western world power. Theodore Roosevelt, who helped mediate the treaty negotiations, later won the Nobel Peace Prize for his achievement.
