Modern perceptions of ancient Greece are almost always based on Athens and Sparta, which is why other city-states and other military units besides the hoplites have been overlooked for thousands of years. For this reason, Greek cavalry forces - including their composition, purpose, techniques, equipment, and developments - are still not very well understood when compared with their naval or infantry counterparts.

Mankind's obsession with felines is an enigma in and of itself. Unlike dogs, famously known as man's most excitable, trustworthy, and loyal friend, cats are oftentimes indifferent, guarded, and yet finicky little furry creatures that only yearn for attention and affection when one is neck-deep in work or otherwise preoccupied. And still, people adore them all the same.

When the American Revolution ended, the United States and Britain reached an impressively comprehensive peace in the Treaty of Paris. Among the important terms of the treaty, Britain recognized the colonies as free and relinquished territorial claims to them. The two sides then negotiated the boundaries that separated the United States from the British colonies in present-day Canada. Additionally, the British and Americans strove to share certain waters, including the Mississippi River and the fishing waters off Newfoundland.

Much of the systematic mechanics and the continual advancement of modern civilization have been shaped by history's most brilliant economists and greatest thinkers. In economics, the most famous figure is undoubtedly Adam Smith, an 18th century philosopher and one of the original champions of the free market, whose ideas were encapsulated in his most famous works, The Wealth of Nations and The Theory of Moral Sentiments, published in the midst of the Scottish Enlightenment.

Riots are an aspect of American history that do not show up much in history textbooks, except for famous disturbances like the Boston Tea Party or the infamous New York City draft riots of 1863. The reality is that the country has experienced thousands of riots, from early colonial times through to the present, and the issues leading up to some of the riots may seem quite peculiar to modern Americans.

In the West, Hinduism is a religion that everyone has heard of but one that few non-practitioners truly understand. Today it is widely regarded as one of the world’s great religions and considered the indigenous religion of India, with practices and beliefs stretching back thousands of years. Sri Krishna, believed to be the eighth incarnation of Vishnu, is without question one of the most popular and instantly recognizable deities within the Hindu pantheon, which encompasses hundreds of Puranic divine beings.

Rome and Carthage rarely could maintain peace after the end of the fourth century BCE. As the two most powerful civilizations in the western Mediterranean region, they were destined to clash, curse or not. Roman historians placed the foundation of Carthage at approximately 814 BCE, several decades before Rome.

When Queen Elizabeth arrived in Lower Fort Garry, Manitoba, in 1970, she was, like many foreign leaders, greeted with a reception and offered tokens by her hosts. What was different about this occasion, however, were the gifts offered: live elk and beaver. In the long-standing tradition of the Hudson’s Bay Company, should the King or Queen arrive in the lands governed by the charter King Charles II granted in 1660, he or she would be presented with two elk and two beavers by the company officials.

Life science is complicated, but its mission is simple – to create a safer, healthier future. This podcast tells the stories behind the science from the perspective of patients, scientists, employees, and advocates that have felt its impact.

This show is a deep dive into data problems, solutions, and innovations disrupting the private markets.

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.

Today, "the Anarchy" is used to describe the period in English history from the death of Henry I in 1135 to the Treaty of Winchester signed by King Stephen and his successor Henry II in 1153. Despite the name, it was an episode of civil war rather than of lawlessness and is interesting for a number of reasons, not the least of which is that it was the first time in English history that a woman claimed the throne of England in her own right.

When people think of ancient Greece, images of philosophers such as Plato or Socrates often come to mind, as do great warriors like Pericles and Alexander the Great. But hundreds of years before Athens became a city, a Greek culture flourished and spread its tentacles throughout the Western Mediterranean region via trade and warfare. Scholars have termed this pre-Classical Greek culture the Mycenaean culture, which existed from about 2000 to 1200 BCE, when Greece, along with much of the Eastern Mediterranean, was thrust into a centuries-long Dark Ages.

Until the 1930s, nationalism had always tended to be a phenomenon of the right-wing or the immigrant anarchists and Bolsheviks. Now, however, the emphasis shifted to the middle ground, and ironically, one of the issues driving Argentine nationalism was the outsized British presence in Argentine affairs, stoked recently by the preferential trade agreement. Perhaps most importantly, the seizure by the British in 1833 of the Islas Malvinas (or as the British termed them, the Falkland Islands) remained a sore point.

Near the end of the 19th century, Otto von Bismarck, the German chancellor, brought the plenipotentiaries of all major powers of Europe together to deal with Africa's colonization in such a manner as to avoid provocation of war. This event, known as the Berlin Conference of 1884-1885, galvanized a phenomenon that came to be known as the Scramble for Africa.

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. For the first billion years or so, there was no life in Earth. Then the first single-celled life-forms, early bacteria and algae, began to emerge.

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".
