Why was the blitzkneg effective?

Blitzkrieg, or "lightning war," was effective due to its emphasis on rapid and coordinated assaults using combined arms tactics, integrating infantry, tanks, and air support. This approach allowed German forces to penetrate deep into enemy territory quickly, disrupting command structures and supply lines. The element of surprise, coupled with speed and mobility, often overwhelmed opponents before they could effectively respond or regroup. Additionally, the psychological impact of such swift victories demoralized enemy troops and populations, further facilitating German advances.
