Victory in Europe Day—known as V-E Day or VE Day—was the public holiday celebrated on 8 May 1945 (in Commonwealth countries, 7 May 1945) to mark the date when the World War II Allies formally accepted the unconditional surrender of the armed forces of Nazi Germany and the end of Adolf Hitler’s Third Reich, thus ending the war in Europe. The formal surrender of the occupying German forces in the Channel Islands was not until 9 May 1945. On 30 April Hitler committed suicide during the Battle of Berlin, and so the surrender of Germany was authorized by his successor, President of Germany Karl Dönitz. The administration headed by Dönitz was known as the Flensburg government. The act of military surrender was signed on 7 May in Reims, France, and on 8 May in Berlin, Germany.
