Members of the World War II generation in Germany came of age following World War I and the German Revolution of 1918–1919. They faced economic hardships related to the Great Depression and Treaty of Versailles as unemployment rose to nearly 40%. Adolf Hitler then rose to power, and many of this generation joined organizations such as the Hitler Youth. In 1935, Hitler instituted military conscription. During the war, nearly 12.5 million members of this generation served in the war and 4.3 million were killed or wounded. By the end of the war, 5 million Germans were dead, including civilians. German cities and towns were devastated by Allied bombing campaigns. 12 million Germans were refugees and many were forced to settle in the Soviet Union. In addition, the Holocaust claimed the lives of millions of German Jews and others. Following the war, the Allies began the denazification and demilitarization of a post-war Germany. Returning German veterans found their country carved up into four zones of occupation; later becoming West Germany and East Germany. In the west, the Marshall Plan resulted in the "Wirtschaftswunder", an economic boom that caused 185% growth between 1950 and 1963. Surviving members of the German World War II generation would go on to experience the Fall of the Berlin Wall and the creation of the European Union. Unlike the Western allies and the Soviet Union, Germany did not honor its veterans, as the association with Nazism continues in contemporary Germany today.
