The early history of our planet covers such vast stretches of time that years, centuries, and even millennia become virtually meaningless. Instead, paleontologists and scientists who study geochronology divide time into periods and eras. The current view of science is that planet Earth is around 4.6 billion years old. The first four billion years of its development are known as the Precambrian period.

By the time Christopher Columbus started setting east from the New World, he had explored San Salvador in the Bahamas (which he thought was Japan), Cuba (which he thought was China), and Hispaniola, the source of gold. As the common story goes, Columbus, en route back to Spain from his first journey, called in at Lisbon as a courtesy to brief the Portuguese King John II of his discovery of the New World.

One September day, New York City suffered a devastating act of domestic terrorism, but that day was not the 11th, and the attack took place over 80 years before the most notorious terrorist attack on America. In 1920, an explosion in the financial district of New York City killed 38 people, injured hundreds more, and caused damage that is still visible on some of Wall Street’s most famous buildings today.

Imagine a feline with the spirit of a lion, the sneakiness of a puma, the terrifying walk of a black bear, and the strong arms of a gorilla. This amazing creature was best known as the saber-toothed tiger, an animal so fearless, it could beat beasts even twice their size! After dinosaurs, few vanished animals are as famous as the woolly mammoths, or in 18th-century scientist George Cuvier’s words, "some kind of extinct elephant".

James Meredith’s struggle to integrate the University of Mississippi in 1962 is still remembered vividly, but the Little Rock Nine are frequently overlooked when it comes to discussing the Civil Rights Movement, despite attempting to integrate Little Rock Central High School five years earlier. For millions of kids, high school is a tumultuous time, but for the Little Rock Nine, the first African American students to attend a previously segregated high school in Little Rock, Arkansas, those years were nightmarish.

In the relatively short history of colonial Australia, one event stands apart, both for its revolutionary spirit and its impact: The Eureka Rebellion of December 3, 1854. This was the only time in Australian history when a government was resisted by free subjects of the Crown in a violent conflict. It only took place in one colony, Victoria, but it was an important event in the evolution of the democratic government in Australia as a whole. The Eureka Rebellion analyzes the chain of events that led to the fighting and its lasting impact.

As soon as man discovered writing, he began engaging in historiography (historical writing and philosophy), but paleoanthropology only really began in the late 1800s. As archaeologists began finding bones in European caves of a human race that was very different than any race in the modern world, the study of paleoanthropology was born. The race of those early humans who were found in the European caves were later termed Neanderthals, and for quite some time, they were believed to have been the race from which many modern humans were directly descended.

If trench warfare was an inevitability during the war, it is only because the events leading up to the First Battle of the Marne were quite different. The armies at the beginning of the war moved quickly through the land, but the First Battle of the Marne devolved into a bloody pitched battle that led to the construction of trenches after the Germans retreated, blocked in their pursuit of Paris.

Not far from the Latakia, Syria, near the Mediterranean Sea coast, is the politically insignificant town of Burj al-Qasab. Throughout most of its history, Burj al-Qasab was overshadowed by Latakia, but this was not always the case. More than 3,000 years ago, on a hill known as Ras Sharma located just outside Burj al-Qasab, a sprawling metropolis much more important and powerful than Latakia, or most other modern cities in the region for that matter once existed. Ras Sharma was the location of Ugarit, an extremely wealthy and powerful Bronze Age city-state.

Although he is unquestionably one of the most studied leaders of the 19th century, Simón Bolívar remains today as enigmatic as he was two centuries ago, when his vision and presence largely inspired the overthrow of the Spanish Empire in the New World.

In the last 50 years, life has been simplified by the awe-inspiring advancements that have been achieved in the world of computer science and technology. In 1976, Steve Jobs and Steve Wozniak unveiled the Apple I, the first-ever computer that operated on a single-circuit board, just five years after a team of IBM engineers introduced the “floppy disk,” which revolutionized data-sharing.

“Scotch-Irish” is an American term that became popular in the latter 1800s, referring to the largely Protestant immigrants to the United States originating in the northern Irish province of Ulster. The majority of Scotch-Irish were people intentionally settled in Ulster as a counter to the native Catholic Irish, who immigrated to Ulster from the lowlands of Scotland and the borderlands between England and Scotland.

World War II stood apart in many ways from every earlier war. The responsibility for mounting an attack on American industry was given to the German military secret intelligence service, the Abwehr, which devised a plan to land saboteurs in America to attack factories, railroads, and perhaps conduct a random bombing campaign against American civilians. The Nazi plan was given the codename of Operation Pastorius, and it was launched in June 1942, just six months after Germany had declared war on America. What followed was one of World War II’s most bizarre spy stories.

Today, the Space Race is widely viewed poignantly and fondly as a race to the Moon that culminated with Apollo 11 “winning” the race for the United States. In fact, it encompassed a much broader range of competition between the Soviet Union and the United States that affected everything from military technology to successfully launching satellites that could land on Mars or orbit other planets in the Solar System.

Overall, Tulsa in 1921 was considered a modern, vibrant city. What had fueled this remarkable growth was oil, specifically the discovery of the Glenn Pool oil field in 1905. Within five years, Tulsa had grown from a rural crossroads town in the former Indian Territory into a boom town with more than 10,000 citizens, and as word spread of the fortunes that could be made in Tulsa, people of all races poured into the city.

In September 2012, on a chilly morning, a Russian kid named Yevgeny Zhenya and his dogs were walking to school, when an awful smell made them stop. The 11-year-old wanted to find out what smelled so bad, and with the help of his furry friends, he went to explore the land. They stumbled upon a giant pair of heels that were covered in an immense pile of snow! What could such a giant thing be?

Imagine a feline with the spirit of a lion, the sneakiness of a puma, the terrifying walk of a black bear, and the strong arms of a gorilla. Sounds cool? Now, add some huge dagger-like fangs. Even cooler, right? This amazing creature was best known as the saber-toothed tiger - an animal so fearless, it could beat beasts even twice their size! As cool as he sounds, this Ice Age feline earned quite a villainous reputation; you can even see them be the bad guys in movies!

La política del “destino manifiesto” aumentó las tensiones con México en la década de 1840. La mitad norte de México formaba la frontera occidental del territorio que había sido adquirido en la Compra de Luisiana. Naturalmente, la noción de que los Estados Unidos se expandieran hacia el Océano Pacífico alarmaba a México, que para entonces comprendía lo que hoy es la costa oeste de los Estados Unidos.

In 1494, there were five sovereign regional powers in Italy: Milan, Venice, Florence, the Papal States, and Naples. In 1536, only one remained: Venice. These decades of conflict precipitated great anxiety among Western thinkers, and Italians responded to the fragmentation, forevermore, of Latin Christendom, the end of self-governance for Italians, and the beginning of the early modern era in a myriad of ways. They were always heavily influenced by the lived experience of warfare between large Christian armies on the peninsula.
