September 2 marks the anniversary of the formal end of World War II, the devastating global conflict that reshaped nations, claimed tens of millions of lives and fundamentally altered the course of modern history.

On September 2, 1945, representatives of Japan and the Allied Powers gathered aboard the battleship USS Missouri in Tokyo Bay to sign the Instrument of Surrender, formally bringing World War II to an end.

The historic ceremony came more than six years after Germany’s invasion of Poland in September 1939 triggered war in Europe and nearly four years after the Japanese attack on Pearl Harbor brought the United States directly into the conflict.

Japan had announced its acceptance of the Allied terms of surrender on August 15, 1945, a date widely commemorated as Victory over Japan. However, it was the signing of the formal surrender documents on September 2 that officially and legally ended the war.

The ceremony aboard the USS Missouri was brief, lasting approximately 23 minutes, but its significance was enormous.

Japanese Foreign Minister Mamoru Shigemitsu signed the Instrument of Surrender on behalf of the Japanese government, while General Yoshijiro Umezu signed on behalf of Japan’s armed forces.

General Douglas MacArthur, Supreme Commander for the Allied Powers, signed on behalf of the Allied nations before representatives of other Allied countries added their signatures to the historic document.

The selection of the USS Missouri as the site of the surrender carried additional symbolism. The battleship was named after the home state of U.S. President Harry S. Truman, who had assumed the presidency following the death of Franklin D. Roosevelt in April 1945.

The surrender brought to a close the deadliest conflict in human history.

World War II engulfed much of the globe, devastated cities and communities and resulted in the deaths of tens of millions of military personnel and civilians.

The end of the war ushered in a dramatically different international order. The United Nations was established in 1945 with the goal of promoting international cooperation and preventing another global conflict, while the United States and Soviet Union emerged as rival superpowers in what would become the Cold War.

Eighty-one years after the surrender aboard the USS Missouri, September 2 remains a date for both remembrance and reflection.
