World War II began on September 1, 1939, when Nazi Germany invaded Poland, prompting Britain and France to declare war. The war in Europe ended on May 8, 1945 (V-E Day), while Japan formally surrendered on September 2, 1945 (V-J Day), bringing the global conflict to a close after six devastating years.
Estimates place the total death toll of World War II between 70 and 85 million people, including both military personnel and civilians. The Soviet Union suffered the greatest losses, with approximately 27 million dead. The conflict also saw the Holocaust, in which six million Jews were systematically murdered by the Nazi regime.
The Battle of Stalingrad (August 1942 - February 1943) is widely considered the most decisive battle of World War II. The Soviet victory destroyed Germany's 6th Army and marked the turning point of the Eastern Front. After Stalingrad, German forces were largely on the defensive for the remainder of the war.
