The Great Depression hit the world hard in the 1930s. The Nazis took advantage of this situation, came to power in Germany, established their first concentration camp and began a systematic persecution of Jews in Europe. In 1939, they invaded Poland and sparked the beginning of World War II.

Other news in the 1930s included the disappearance of aviator Amelia Earhart over the Pacific, a wild and murderous crime spree by Bonnie Parker and Clyde Barrow, and the imprisonment of Chicago mobster Al Capone for income tax evasion. More »

World War II was already underway by the time the 1940s began, and it was definitely the big event of the first half of the decade. The Nazis established death camps in their effort to murder millions of Jews during the Holocaust, and they were liberated as the Allies conquered Germany and the war ended in 1945.

Shortly after World War II ended, the Cold War began between the West and the Soviet Union. The 1940s also witnessed the assassination of Mahatma Gandhi and the beginning of apartheid in South Africa. More »
