What did the allies do to take Europe back from the axis powers?

The Allies launched a series of coordinated military campaigns to reclaim Europe from the Axis powers. Key operations included the D-Day invasion of Normandy in June 1944, which established a crucial foothold in France, and the liberation of Paris shortly thereafter. Additionally, the Allies conducted intense bombing campaigns against German industrial centers and engaged in significant ground battles, such as the Battle of the Bulge, to weaken Axis forces. These efforts ultimately culminated in the unconditional surrender of Germany in May 1945.
