Chronological Overview
Prelude to War (1931-1939)
The seeds of World War II were sown in the aftermath of World War I, with the rise of fascism in Europe and Japan’s imperial ambitions in Asia. Key events leading up to the war included Japan’s invasion of Manchuria in 1931, the Italian invasion of Ethiopia in 1935, and the German annexation of Austria and Czechoslovakia in 1938.
Outbreaks of Hostilities (1939-1941)
On September 1, 1939, Germany invaded Poland, marking the official start of World War II. Britain and France responded by declaring war on Germany two days later. The war quickly spread across Europe, with Germany and its allies conquering much of the continent by 1940. In Asia, Japan expanded its control over vast territories, including Manchuria, Korea, and parts of China.
The Turning Tide (1941-1943)
The year 1941 proved to be a turning point in the war. Germany’s invasion of the Soviet Union and Japan’s attack on Pearl Harbor brought the United States into the conflict on the side of the Allies. With the vast industrial might of the United States behind them, the Allies began to gain the upper hand.
Liberation and Victory (1944-1945)
In 1944, the Allies opened a second front in Europe with the D-Day landings in Normandy. They also made significant gains in the Pacific, reconquering key islands and bringing the war ever closer to Japan. In August 1945, the United States dropped atomic bombs on Hiroshima and Nagasaki, leading to Japan’s surrender and the end of the war.
Major Events
The Battle of Britain
From July to October 1940, the Royal Air Force (RAF) successfully defended the United Kingdom against a sustained German air attack. This battle was a crucial turning point in the war, as it prevented Germany from invading Britain and gaining control of the English Channel.
The Invasion of the Soviet Union
In June 1941, Germany launched Operation Barbarossa, a massive invasion of the Soviet Union. This invasion was the largest military operation in history, involving over 3 million German soldiers. The Soviet Union suffered heavy losses but managed to hold back the German advance, eventually turning the tide of war on the Eastern Front.
The Battle of Midway
In June 1942, the United States Navy defeated the Imperial Japanese Navy in a decisive battle in the Pacific. This battle halted Japan’s expansion in the Pacific and marked a major turning point in the war against Japan.
