This decade was dominated by the first "total war" -- World War I. It also saw other huge changes during the Russian Revolution and the beginning of Prohibition. Tragedy struck when a fire rampaged through New York City's Triangle Shirtwaist Factory; the "unsinkable" Titanic hit an iceberg and sank, taking the lives of more than 1,500; and the Spanish flu killed millions around the world.

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.

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.

The 1950s are sometimes referred to as the Golden Age.

The Cold War continued as the space race between the United States and the Soviet Union began.

The 1950s also saw segregation ruled illegal in the U.S. and the beginning of the civil rights movement.

'To many, the 1960s can be summed up as the Vietnam War, hippies, drugs, protests and rock 'n roll. A common joke goes "If you remember the '60s, you weren't there."

Although those were important aspects of this decade, other events occurred as well. For instance, the Berlin Wall was built, the Soviets launched the first man into space, President John F. Kennedy was assassinated, the Beatles become popular, and the Rev. Dr. Martin Luther King Jr. made his "I Have a Dream" speech.
