Do you know which of these historical events came first?

Julius Caesar was the (sometimes brutal) dictator of the Roman Empire. He was assassinated in 44 B.C.

The Civil War ripped America to shreds in the 1860s. Chernobyl happened in 1986, and the tsunami? That was 2004.

The Treaty of Versailles signaled the end of World War I. Sadly, many people knew it was simply a stopgap solution and that a new world war was virtually inevitable. They were right.

Clearly, World War I preceded World War II. The Great War devastated Europe. It started in 1914 and ended in 1918.

The 79 A.D. eruption of Mount Vesuvius still ranks as one of the most epic natural disasters in human history. It completely wiped out two cities, Pompeii and Herculaneum.

If you guessed the Panic of 1901, you're right. This was the very first stock market crash on the New York Stock Exchange, and it wiped out many investors' life savings.

The British Open is an incredibly old event, first played in 1860. It was played on Prestwicks' 12-hole golf course, and the few people who participated played the course three times.

The Holocaust, Hitler's systematic killing of civilians, occurred during World War II. The Cold War began at the conclusion of that war.

There was no America at all until the American Revolution, so this one came first. It ended in 1783. The Spanish-American War didn't happen for another century.

The Apollo 11 mission, the one that landed the first men on the moon, happened in 1969. The Cassini-Huygens probe wasn't launched until 2004. Spirit and Opportunity also landed on Mars in 2004.

The Reformation transformed Europe in the 16th and 17th centuries. Before this event, the Catholic Church had a stranglehold on society. Reformation helped to bring the church back to a more Christian way of life.

The Black Plague ravaged humankind in the 14th century, killing perhaps 200 million people. The Industrial Revolution didn't take hold until the 18th and 19th centuries.

The attack on Pearl Harbor happened on a date that will live infamy -- December 7, 1941. The Vietnam War consumed the late 60s and the Rwandan genocide happened in the 90s.

Jesus died in around 33 A.D., long before either of those other famous men. He was famously crucified due to an order by ruler Pontius Pilate.

The Battle of Thermopylae happened in 480 B.C., when a small group of Spartan warriors repeatedly repelled much larger Persian forces. It's the battle featured in the movie "300."

As much as we'd like to see Big Bird throw down on Elmo, there was no Sesame Street Civil War. The American Civil War happened in the 1860s, decades before the Spanish Civil War of the 1930s.

The 9/11 attacks happened in 2001. Hurricane Katrina struck in 2005, exposing many flaws in America's disaster response systems. So the Crash of 1987 came first.

As you can probably guess from the name, the Massacre of Thessalonica happened in antiquity, back in 390 A.D. The Nanking Massacre was one of the ugliest events of the 1930s. And the Battle of the Little Bighorn happened in 1876.

In 1939, the Nazis invaded Poland, in effect triggering World War II. The invasion of Normandy came in 1944, as the Allies tried to retake ground from the German aggressors.

In 1666, an enormous fire enveloped London. Few people died, but more than 10,000 buildings burned, gutting much of the city's ancient core.

The Renaissance started in the 1300s, heralding a new age for humankind, one in which people generated new ideas and art at a stunning pace.

The Wars of the Three Kingdoms are also known as the British Civil Wars. In the 17th century, these wars found England, Scotland and Ireland often at violent odds with one another.

This is one of our tougher ones due to the close timeline. Princess Diana died in a terrible 1997 car wreck. But Nixon died three years earlier. B.B. King passed much later, in 2015.

The French Revolution ended all the way back in 1799. The Chinese Great Leap Forward ended in 1962, and, instead of improving the country, it probably caused a huge famine.

The Gutenberg printing press was invented in around 1440. This fantastic invention changed the way human beings shared and documented information of all kinds.

The great ship Titanic sank in the North Atlantic Ocean in 1912. The Hindenburg airship disaster happened in 1937. More than 1,500 people died after the Titanic went down.

Muhammad lived until about 630 A.D., long before Pope Pius IX, who served in the 19th century. Mother Teresa, of course, is a 20th-century icon.

The Roswell Incident happened in 1947 and became the world's most famous UFO incident. In 1960, an American U-2 spy plane was shot down inside Soviet airspace, creating an international scandal of sorts.
