The Neolithic period came before the Bronze Age and is generally regarded as the final subdivision of the Stone Age. During this time, communities domesticated plants and certain animals but still relied on hunting and gathering to a considerable extent, and beginning sometime around 7000 BCE, handmade pottery was developed, along with more advanced stone axes that enabled people to clear vast forests.

The crucial importance of education in China, a prized virtue instilled in the population among all classes by beloved teacher and philosopher Confucius in the 6th century BCE, generated an unprecedented and long-lived golden age of literature and art. It also gave rise to a cornucopia of transformative innovations and groundbreaking technology, particularly following the dawn of the Common Era.

The KGB is one of the most famous abbreviations of the 20th century, and it has become synonymous with the shadowy and often violent actions of the Soviet Union’s secret police and internal security agencies. In fact, it is often used to refer to the Soviet state security agencies throughout its history, from the inception of the inception of the Cheka (Extraordinary Commission) in 1917 to the official elimination of the KGB in 1992.

In 1968, biologist John Calhoun began an experiment at the National Institute of Mental Health in Maryland. Calhoun was interested in discovering the factors that drove and limited rodent population growth; he had joined the Rodent Ecology Project in Baltimore in 1946, and he and other members of the project had become interested in understanding how to reduce rodent pests in America’s cities without the use of poison.

Before any type of unified political entity named Israel existed, the Jewish groups whose descendants would later form Israel identified themselves by their particular tribe. If asked their nationality or country of origin, they would likely identify themselves as Danites (from the tribe of Dan; Ex. 31:6) or Ephraimites (from the tribe of Ephraim; Judg. 12:5), etc.

What happens when you put good people in a bad place? That was the question that an experiment in 1971 set out to answer when Stanford University professor and psychologist Philip Zimbardo used funding provided by the U.S. Office of Naval Research to create a make-believe prison in the basement of a university building. Male students were offered the chance to take part in the two-week experiment (and to make $15 per day). All applicants were carefully screened to ensure that they were healthy, emotionally and psychologically stable. 24 men were selected out of 75 that had applied.

War has always led to prisoners. In ancient times, many were turned into slaves by the victorious armies, while in medieval Europe, they were often returned to their families in return for a ransom, leading to fortune or poverty depending upon which side one was on. By the Napoleonic era, as armies grew in size and professionalism, many were kept in camps for the duration of the fighting, their captors not wanting to restore their enemies' manpower while the fate of nations hung in the balance.

Early in 1799, Napoleon advanced against France’s erstwhile enemy, the Ottoman Empire, invading modern Syria (then the province of Damascus) and conquering the cities of Gaza, Jaffa, Arish and Haifa. However, with the plague running rampant through his army and his lines of supply from Egypt stretched dangerously thin, Napoleon was unable to destroy the fortified city of Acre and was forced to retreat. The retreat cost him almost all of his wounded as, harassed by enemy forces, he was forced to abandon most of his casualties to the Ottomans’ mercy, or lack thereof.

During the first half of the 1st millennium CE, an empire arose in Persia that extended its power and influence to Mesopotamia in the east, Arabia in the south, the Caucasus Mountains in the north, and as far east as India. This empire, known alternatively as the Sasanian Empire or Sassanid Empire, was the last of three great dynasties in Persia - the Achaemenid and the Parthian being the first two dynasties - before the rise of Islam.

In the first half of the 20th century, war was fought on a global and industrial scale. Millions of men were flung into the grinder of World War I and World War II, leading to commensurately huge numbers of prisoners of war (POWs). Camps were built to hold thousands of captives, with their own barracks blocks, parade grounds, and even farms. All of this meant that prisoners were taken across the world, and prisoners of war were typically comprised of two classes: officers and other ranks.

In many ways, the story of Camp Douglas outside of Chicago is the story of the Civil War itself. The camp got its start as a brand new facility filled with men ready to fight a war that most on both sides believed would last only a few months. However, as the war went on, the facilities were overwhelmed by the sheer scale of the damage and the massive numbers of people involved.

The ancient world was full of many fantastic cities and places, and like today’s major cities, the great ancient cities were hubs of trade, religion, and science. Writing was first invented in ancient cities, and many important scientific discoveries were also made in them, some of which are still used in the modern world. Among the many cities of the ancient world, Rome and Athens may come to mind first, but the city of Babylon in the land of Mesopotamia was already an ancient, venerated city when the others were still inconsequential settlements.

The current view of science is that 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 on Earth, and then the first single-celled life-forms, early bacteria and algae, began to emerge. It’s unknown where they came from or even if they originated on this planet at all, but this gradual development continued until suddenly (in relative geological terms), more complex forms of life began to emerge.

Many ancient civilizations have influenced and inspired people in the 21st century. The Greeks and Romans continue to fascinate the West today. But of all the world’s civilizations, none have intrigued people more than the Mayans, whose culture, astronomy, language, and mysterious disappearance all continue to captivate people. In 2012 especially, there has been a renewed focus on the Mayans, whose calendar has led many to speculate the world will end on the same date the Mayan calendar ends. The focus on the “doomsday” scenario, however, has overshadowed the Mayans’ true contribution.

As the Japanese swept across Asia in the early years of World War II, the retreating Allies looked for ways to keep up the fight. In Malaya and Burma, agents had been left behind to stir resistance behind enemy lines, building up anti-Japanese operations from the safety of the jungle. In China, the American Office of Strategic Services helped both Nationalists and Communists in resisting the Japanese.

The striking saga of the Glorious Revolution is one that continues to fascinate historians around the world today. Some chroniclers have referred to these events as the “Bloodless Revolution,” but other historians say otherwise. The ruthless game of politics that William and James played may have been somewhat bloodless in comparison to history's greatest rebellions, but the rebels, soldiers, and other pawns who lost their lives along the way must not be forgotten.

Was he “the greatest human being ever to occupy 10 Downing Street,” or a man whose “brilliant but unsound judgement resulted in detrimental consequences for Britain and for the world”? Decades after his death, debate still rages over Sir Winston Churchill’s contribution to history, though all agree that it was profound no matter which way it’s viewed. But now that wartime nostalgia has mostly washed away, the views of Churchill are more divergent than ever.

Given that there’s such little margin for error in a submersible, many submarine losses remain sources of intrigue and mystery, and during World War II, few sinkings were as controversial as the Surcouf, a Free French submarine that disappeared in the Caribbean in 1942. When the Surcouf launched in 1929, it was a technological marvel. This wasn’t a conventional submarine at all, but a 3,300-ton, 300-foot-long submersible light cruiser.

Conspiracy theories, and particularly the belief that elements of the world are secretly controlled by individuals or groups, have been around for as long as people have lived in groups. Perhaps that’s inevitable - after all, those who are excluded from power are very likely to be inclined to see their position not as an outcome of their own choices or situation but because of the secret machinations of shadowy groups.
