What year did World War II end?

World War II concluded in 1945, marking a significant turning point in global history. The war effectively ended in Europe with the unconditional surrender of Nazi Germany on May 8, 1945, a day commemorated as Victory in Europe (VE) Day. Following this, the conflict continued in the Pacific until Japan's surrender on September 2, 1945, which is recognized as Victory over Japan (VJ) Day. This surrender led to the official end of World War II, culminating in the establishment of the United Nations and setting the stage for a new geopolitical order.

The other options indicate years that are either before the conflict began or years that followed the war's conclusion. 1939 marks the official start of the war with Germany's invasion of Poland. The years 1950 and 1963 are notable in their own rights, but they fall outside the timeline of World War II's duration, which is firmly anchored between 1939 and 1945.
