World War II, a devastating global conflict that involved numerous nations and spanned multiple continents, ultimately drew to a close in 1945. The cessation of hostilities was marked by two significant events: the capitulation of Germany and the subsequent surrender of Japan.

The first of these events occurred on May 7th, 1945, when Germany, facing insurmountable odds and the relentless advance of Allied forces, officially surrendered. This act of submission was formalized with the signing of the German Instrument of Surrender, which took effect on May 8th - a day now commemorated as Victory in Europe Day (VE Day).

Several months later, on September 2nd, 1945, Japan acquiesced to the Allied Powers' demand for an unconditional surrender. This monumental decision was precipitated by the devastating impact of the atomic bombings of Hiroshima and Nagasaki, as well as the Soviet Union's declaration of war against Japan. Aboard the USS Missouri, representatives of the Japanese government signed the Japanese Instrument of Surrender, thereby marking the end of World War II. The day has since been designated as Victory over Japan Day (VJ Day).
