World War II  1939 - 1945

World War Two, spanning from 1939 to 1945, was a global conflict that involved numerous nations and reshaped the course of history. The war emerged from the aftermath of World War One and the unresolved issues of the Treaty of Versailles, leading to escalating tensions in Europe and Asia. On September 1, 1939, Germany, led by Adolf Hitler, invaded Poland, prompting Britain and France to declare war, officially initiating the conflict. The war can be divided into major theaters: the European Theater and the Pacific Theater.

Key events in the European Theater included the Blitzkrieg tactics employed by Germany, resulting in the swift conquest of several countries. The Battle of Britain (1940) saw the Royal Air Force successfully repelling the German Luftwaffe's air attacks. In 1941, Germany launched Operation Barbarossa, a massive invasion of the Soviet Union. Meanwhile, Japan's expansionist ambitions led to its invasion of China and other Asian territories, culminating in its attack on Pearl Harbor on December 7, 1941, which brought the United States into the war.

Significant figures during World War Two included Winston Churchill, who led Britain as Prime Minister and played a pivotal role in rallying the Allies; Franklin D. Roosevelt, the U.S. President who guided America through much of the war and formed key alliances; and Joseph Stalin, the Soviet leader who oversaw the nation's resistance against German forces. Notable battles included Stalingrad (1942-1943), a turning point on the Eastern Front, and D-Day (June 6, 1944), the Allied invasion of Normandy, which led to the liberation of Western Europe.

The war concluded in 1945 with the unconditional surrender of Germany in May and Japan in August, after the U.S. dropped atomic bombs on the cities of Hiroshima and Nagasaki. World War Two resulted in unprecedented destruction and loss of life, with an estimated 70-85 million fatalities worldwide. The war's aftermath brought about the formation of the United Nations, the division of Germany, the beginning of the Cold War between the United States and the Soviet Union, and significant geopolitical changes that shaped the modern world.
