World War I ended in 1918, when Germany signed an armistice agreement with the victorious Allies. The war had cost the lives of more than 9 million combatants plus millions of civilians. Meanwhile, an even more deadly threat emerged: the influenza pandemic, which would take another 50 million lives worldwide. Bolshevik revolutionaries executed the Romanov family, ending 300 years of Russian imperial rule. On the U.S. homefront, Congress enacted daylight savings time, only to repeal it the following year.

In 1865, the American Civil War came to an end, President Lincoln was assassinated and the 13th amendment was ratified, abolishing slavery in the U.S. The Secret Service came into being, originally created to prevent widespread counterfeiting that plagued the financial system. Elsewhere in the world, rebels in the Dominican Republic forced out Spanish occupiers to restore their country’s independence, and in England, Lewis Carroll published “Alice’s Adventures in Wonderland.”

Riots in Detroit… San Francisco's Summer of Love… the Six-Day War in the Middle East… Elvis and Priscilla's Vegas wedding... 1967 was a momentous year around the world. It also a year of firsts: the first successful human heart transplant in South Africa (the recipient lasted 18 days), the confirmation of the first Black Supreme Court Justice in the U.S. (Thurgood Marshall) and the first McDonald’s Big Mac (price: 45 cents).

World War I pitted Germany, Austria-Hungary and the Ottoman Empire against Great Britain, the United States, France, Russia, Italy and Japan.
