The significant treaty that marked the end of World War II in Europe was the German Instrument of Surrender signed on May 7, 1945, and ratified on May 8, known as V-E Day (Victory in Europe Day). This surrender marked the official conclusion of hostilities in Europe, acknowledging Germany's defeat. The treaty significantly reshaped the political landscape of Europe, leading to the division of Germany and the onset of the Cold War. It represented the triumph of the Allied powers and paved the way for post-war recovery and reconstruction efforts across the continent.
