This article provides a detailed timeline of Truman’s presidency, highlighting key events and milestones.

Early Presidency and World War II: 1945

  • April 12, 1945: President Franklin D. Roosevelt dies suddenly from a cerebral hemorrhage. Vice President Harry S. Truman is sworn in as the 33rd President of the United States. Truman’s assumption of office occurs during the final stages of World War II, and he inherits the complex responsibilities of leading the nation through the war’s conclusion.
  • April 16, 1945: Truman attends the San Francisco Conference, where the United Nations Charter is drafted. The conference marks a significant step in establishing an international organization aimed at promoting peace and cooperation.
  • May 7, 1945: Germany surrenders unconditionally to the Allied forces, marking the end of hostilities in Europe. This day is celebrated as Victory in Europe (V-E) Day. Truman, along with Allied leaders, begins planning for the post-war reconstruction of Europe and the reorganization of international relations.
  • July 16, 1945: The first successful test of an atomic bomb, known as the Trinity Test, takes place in New Mexico. Truman is informed of the successful test and the potential implications for the war and international diplomacy.
  • August 6, 1945: The United States drops an atomic bomb on Hiroshima, Japan, followed by another bomb on Nagasaki on August 9. These events contribute to Japan’s decision to surrender and end World War II.
  • August 14, 1945: Japan announces its surrender, marking Victory over Japan (V-J) Day. The official surrender is signed on September 2, 1945, aboard the USS Missouri. Truman’s decisions during this period have profound implications for global geopolitics and the future of nuclear diplomacy.

Post-War Challenges and the Beginning of the Cold War: 1945-1947

  • October 24, 1945: The United Nations is officially established. Truman plays a key role in supporting the formation of the UN and its mission to maintain international peace and security.
  • March 12, 1947: Truman delivers his famous Truman Doctrine speech before Congress. In this address, he outlines the policy of providing economic and military aid to countries threatened by communism, specifically Greece and Turkey. The Truman Doctrine becomes a cornerstone of U.S. foreign policy during the Cold War.
  • June 5, 1947: Truman endorses the Marshall Plan, named after Secretary of State George C. Marshall. The plan provides economic assistance to rebuild European countries devastated by World War II. The goal is to prevent the spread of communism and promote economic recovery.
  • July 26, 1947: Truman signs the National Security Act into law. This Act reorganizes the U.S. military and intelligence agencies, leading to the creation of the Department of Defense, the National Security Council (NSC), and the Central Intelligence Agency (CIA).

Domestic Policy and Political Challenges: 1948-1950

  • November 2, 1948: Truman wins re-election in a surprising upset victory against Republican candidate Thomas E. Dewey. The election is notable for Truman’s vigorous campaign and the famous “Dewey Defeats Truman” headline that mistakenly declared Dewey the winner.
  • March 29, 1949: The North Atlantic Treaty Organization (NATO) is established. Truman supports the formation of NATO as a military alliance designed to counter Soviet aggression and strengthen collective security among Western democracies.

The Korean War and Domestic Policy: 1951-1952

  • September 15, 1950: General Douglas MacArthur leads a successful amphibious invasion at Inchon, South Korea. This operation significantly shifts the momentum of the Korean War in favor of the United Nations forces.
  • November 24, 1950: The Chinese People’s Volunteer Army enters the Korean War, leading to a major counteroffensive against UN forces. The involvement of Chinese troops escalates the conflict and complicates U.S. military strategy.
  • April 11, 1951: Truman relieves General Douglas MacArthur of his command in Korea. The dismissal is controversial and results from disagreements over military strategy and public statements made by MacArthur. Truman’s decision reflects his commitment to civilian control of the military and his approach to managing the Korean conflict.
  • June 27, 1951: The first negotiations toward an armistice are held in Kaesong, Korea. The armistice talks eventually lead to a ceasefire agreement signed on July 27, 1953, which establishes the Korean Demilitarized Zone (DMZ) and ends active hostilities.

Legacy and End of Presidency: 1953

  • January 20, 1953: Truman’s presidency concludes with the inauguration of Dwight D. Eisenhower as the 34th President of the United States. Truman leaves office with a mixed legacy, having faced significant challenges during his presidency but also making lasting contributions to American foreign policy and domestic reforms.
