How was blitzkrieg stopped?

Blitzkrieg, or "lightning war," was effectively stopped through a combination of strategic counteroffensives and the exhaustion of German resources. Key battles, such as the Soviet Union's defense at Stalingrad in 1942-1943, marked a turning point, as they halted German advances on the Eastern Front. The Allies also coordinated their efforts in Western Europe, particularly during D-Day in 1944, which led to the liberation of occupied territories and the eventual defeat of Nazi Germany. Enhanced communication, improved tactics, and the sheer industrial capacity of the Allies played crucial roles in overcoming the initial rapid successes of blitzkrieg.
