What significant event did Roosevelt help mediate in 1905?

  1. The end of the Russo-Japanese War

  2. The signing of the Treaty of Paris

  3. The Cuban revolution against Spain

  4. The opening of the Panama Canal

The correct answer is: The end of the Russo-Japanese War

The significant event that Roosevelt helped mediate in 1905 was the end of the Russo-Japanese War. This conflict, which had erupted between Russia and Japan over rival imperial ambitions in Manchuria and Korea, escalated into a full-scale war from 1904 to 1905. Seeking to position the United States as a power broker on the world stage and maintain stability in the region, Roosevelt offered to mediate peace talks between the two nations. His efforts culminated in the Treaty of Portsmouth, which was signed in September 1905. Roosevelt's successful mediation not only earned him the Nobel Peace Prize in 1906 but also established the United States as a significant player in international diplomacy, particularly in East Asian affairs. This event marked a turning point in U.S. foreign policy and illustrated Roosevelt's commitment to promoting peace while also asserting American influence globally.
