“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. 

Sigmund Freud (1856-1939) is known around the world as the “Father of Psychoanalysis,” and for good reason. If anything, Freud’s first patient was himself. A sufferer of psychosomatic symptoms, Freud diagnosed himself as having a repressed antagonism against his father. From there, Freud began to build on his now famous concepts of the unconscious, infantile sexuality and repression. And of course, there’s his famous theory on the structure of the mind, which has made Id and Ego a commonly used part of the English lexicon. 

Despite the pope’s aversion to temporal glory, his authority tended to fill the vacuum in the West left when the last Western Roman emperor, Romulus Augustus, was deposed in 476. The pope would continue to do so until 800, when Charlemagne would allow himself to be crowned Emperor of the West in Rome upon receiving his crown from Pope Leo III. This created modern Europe and was the culmination of two centuries of papal policy aimed at securing its independence from the Byzantine Empire in Constantinople. 

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.

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.

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.

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. 

The Romans were master builders, and much of what they built has stood the test of time. Throughout their vast empire, they have left grand structures, from the Forum and Pantheon in Rome, to the theatres and hippodromes of North Africa, and the triumphal gates in Anatolia and France. Wherever they went, the Romans built imposing structures to show their power and ability, and one of their most impressive constructions was built on the northernmost fringe of the empire.

The Middle Ages witnessed almost constant warfare in Europe, so mercenaries were a constant on the battlefield, but the 15th century also saw the rise of mercenary usage by the increasingly wealthy aristocracy. At the time, England and France existed in smaller versions than in the modern age, while the Spanish had unified into a few large kingdoms and were slowly pushing the Moors off the Iberian Peninsula. Norway and Hungary were larger than they are now, but otherwise, most of Europe was a patchwork quilt of small, constantly warring states.

Although it is no longer quite as well remembered as it was thousands of years ago, one of the most important cities in the ancient world was Ephesus, a city that dates back nearly 3,000 years and can lay claim to the Temple of Artemis, one of the seven wonders of the ancient world. Moreover, while Sparta and Athens were often the centers of power in ancient Greece, Ephesus, located in present-day Turkey on the coast of Ionia, was an instrumental part of the Ionian League.

The United States Camel Corps was a military experiment in the 1850s that brought camels from Egypt and Turkey to Texas and California. The cast of characters in this story is larger than life and includes U.S. Army and Navy officers, explorers, writers, politicians, and diplomats...How long the name of “Camel Corps” has been in existence is unknown, but it has been used in literature for close to a century. What the troopers themselves called the unit remains unknown. The United States Camel Corps looks at the unique unit, from its origins to its record.

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.

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 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.

The early history of Earth 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 Earth is around 4.6 billion years old, and the first four billion years of its development are known as the Precambrian period.
