1943

1943 was a decisive year in World War II, marked by major battles, political shifts, and strategic planning that helped set the stage for the Allied offensives of 1944. The year featured several turning points across Europe, Africa, the Pacific, and the broader international effort against the Axis powers.

In Europe and North Africa, the Casablanca Conference held in January brought together Franklin D. Roosevelt and Winston Churchill to align Allied strategy. The war in the east saw the German surrender of the 6th Army at Stalingrad on February 2, a critical Soviet victory that shifted momentum to the Allies on the Eastern Front. The Tunisian campaign concluded with Axis forces surrendering in May, securing North Africa for the Allies. The summer included the Battle of Kursk (July–August), the largest tank engagement in history, which reinforced Soviet strategic momentum. In July, Mussolini was deposed, and Italy signed an armistice with the Allies in September, leading to the occupation of northern Italy by German forces and the establishment of the Italian Social Republic.

Diplomatic developments occurred at the Tehran Conference in November–December, where Roosevelt, Churchill, and Stalin coordinated plans for a Western Front in Europe and discussed the postwar order and war against Japan. The Warsaw Ghetto Uprising in April–May highlighted resistance within occupied territories and the ongoing atrocities of the Holocaust.

In the Pacific and air war, Allied campaigns continued with the conclusion of the Guadalcanal campaign in early 1943 and major amphibious operations such as Tarawa in November. Allied bombing intensified, including Operation Gomorrah against Hamburg in July, causing extensive destruction and casualties.

Overall, 1943 produced strategic victories and political shifts that paved the way for renewed Allied offensives in 1944.
