Germany's expansionist aggression under the Nazi regime prompted Britain and France to declare war in September 1939 following the invasion of Poland. German military strategy aimed at rapid conquest of Western Europe to secure its western flank, leading to planned offensives against the Low Countries and France.
The Western Front encompassed two major phases of combat: the rapid German conquest of Luxembourg, the Netherlands, Belgium, and France in May–June 1940, followed by an air war culminating in the Battle of Britain; and the large-scale Allied ground offensive beginning with the Normandy landings in June 1944, supported by a strategic bombing campaign, pressing eastward into Germany.
The Allied advance from Normandy through France and into Germany resulted in the unconditional surrender of Nazi Germany in May 1945. Occupied Western European nations were liberated, and the post-war order in Western Europe was fundamentally reshaped, leading to new political boundaries and the beginning of reconstruction under Allied occupation.
