Wirtschaftswunder, or 'economic miracle,' refers to the rapid reconstruction and growth of the West German economy during the late 1940s and 1950s, following the devastation of World War II. This economic resurgence was characterized by significant industrial growth, low unemployment, and rising living standards, largely fueled by U.S. aid and effective economic policies. The term highlights how West Germany transformed from a war-torn country into one of the world's leading economies in a short period.
