World War II & The Holocaust (1939–1945)
World War II (1939–1945) was the deadliest conflict in human history, fought between the Axis powers (Nazi Germany, Fascist Italy, Imperial Japan) and the Allied powers (Great Britain, the Soviet Union, the United States, and China). The war commenced on September 1, 1939, with Germany's invasion of Poland, followed by blitzkrieg conquests across Western Europe. Turning points included the British victory in the Battle of Britain, the Soviet defense at the Battle of Stalingrad (1942–43), and the Allied Normandy landings (D-Day) on June 6, 1944. Concurrently, the Nazi regime orchestrated the Holocaust, systematically murdering six million European Jews. The war ended in 1945 following Hitler's defeat and the US atomic bombings of Hiroshima and Nagasaki.
