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.

The IRGC is notable for its involvement in conflicts around the Middle East, particularly in supporting Shi'a groups through military training and finance, as well as backup support on the battlefield. This is not to say the IRGC enters into conflicts for the sake of being involved, but rather, they see these particular situations as serving the interests of Iran and furthering their brand of Shi'ism, a sect of Islam.

In 2014, the International Space Station unleashed a series of photographs that had netizens around the globe simultaneously slapping their cheeks in disbelief for more reasons than one. For starters, the world was astounded by the crisp definition and stellar resolution of the images captured by the space agency's NightPod lenses, which showed striking satellite shots of the world at nighttime, illuminated by its dazzling city lights. But it was a close-up snap of the China-North Korea border that elicited reactions far greater than the rest, for the image, as terrific as it was, was equally troubling.

The man known to most of the world as Emperor Hirohito ruled during some of the most tumultuous years in Japanese history. When he came to the throne in 1926, he inherited control of a country which had only recently emerged as a major industrial and world power. Through the aggressive expansion and wars of the 1930s, Hirohito was at the head of one of the world’s foremost powers. Throughout the maelstrom of World War II, he remained in power, a distant and, to most outsiders, inscrutable factor in the rise of the Japanese Empire.

Over 450 years after his reign, Henry VIII is still the most famous and recognizable King of England, but it’s for all the wrong reasons. Though well regarded by contemporaries as a learned king and "one of the most charismatic rulers to sit on the English throne", he is best remembered today for his gluttony and multiple marriages. History for Kids: An Illustrated Biography of King Henry VIII chronicles Henry VIII’s life and reign.

History for Kids: The Illustrated Life of Queen Elizabeth I chronicles the life and reign of England’s most famous queen, but it also humanizes the woman who ruled one of the world’s most powerful kingdoms in an age dominated by men. Elizabeth inherited her grandfather’s political acumen and her father’s magnificence, thus creating not just one of the most colorful courts in Europe but also one of the most effective governments in English history.

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. One of the most widely discussed conspiracy theories concerns what has become known as the New World Order.

The borderlands of the paranormal include some bizarre stories. However, none are more strange or unsettling than the tale of what became known as the Philadelphia Experiment, an alleged effort during World War II to make a US Navy ship invisible by using electrical power.

Caesar is still remembered for winning a civil war and helping bring about the end of the Roman Republic, leaving a line of emperors in its place, but it’s quite possible that none of what Caesar did would’ve happened without the template for such actions being set 40 years earlier.

For millions of kids, high school is a tumultuous time, with social highs and lows, academic pressure, and extracurricular wins and losses, 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.

El siglo XVII estuvo marcado por múltiples revoluciones predemocráticas que estallaron en ambos hemisferios. En Europa y sus vecinos del este, se libraron incesantemente guerras que cambiaron las fronteras.

The phenomenon of “conspiracy” or “fringe” theories has always been with people, which makes sense since captivating and entertaining hypotheses arouse the public interest with seemingly sound conclusions that are often based on incomplete, unrelated, or erroneous suppositions. However, with the correct tweaking, they often appear to propound airtight arguments. Conspiracy theories make good use of real or imagined individuals or organizations operating behind a curtain of secrecy manipulating the action.

The Congress of Vienna, which took place over several months during 1814 and 1815, was an attempt to resolve the numerous challenges presented by Napoleon’s expansion and his subsequent defeat. The talks have been seen as a critical moment in European history, and depending on the point-of-view, the results were either a diplomatic breakthrough or the last gasps of the continent’s conservative elites. It was also a crucial step toward German unification, although this was not clear at the time.

In a world fascinated by men like Alexander the Great and Julius Caesar, Genghis Khan is one of history’s greatest and most famous conquerors. No man, before or since, has ever started with so little and gone on to achieve so much.

In a world fascinated by men like Alexander the Great and Julius Caesar, Genghis Khan is one of history’s greatest and most famous conquerors. No man, before or since, has ever started with so little and gone on to achieve so much. From a noble family but raised in poverty that drove him to the brink of starvation, Genghis Khan rose to control the second-largest empire the world has ever known (the largest being, arguably, the British Empire of the 18th and 19th centuries), and easily the largest empire conquered by a single man.

During the last 100 years, Susan B. Anthony has been one of the most venerated women in American history. In the process of becoming one of the most famous Americans of her era, Anthony’s legacy has overshadowed many of her contemporaries who were also active in the fight for civil rights. Among them, few led as interesting or progressive a life as Dr. Mary Edwards Walker, who grew up in a family that encouraged every kind of pursuit for girls and provided an educational foundation that would propel Walker in many fields.

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.

As labor unions and movements began to form and coalesce in the 19th century, the tensions between workers and companies led to demonstrations, encounters, and even conflicts that descended into violence. Among those, few were as notorious as the fight that took place on April 20, 1914 at Ludlow in the Southern Colorado coalfields between the Colorado National Guard and striking miners at a United Mine Workers camp. In the previous several decades, there had been a number of violent incidents during strikes, but in 1914, the Ludlow tragedy deeply shocked the nation.

Over the course of his life, Ely Samuel Parker was a Seneca chief, a civil engineer, a close friend and adjutant to General Ulysses S. Grant, an advocate for the Indian peoples, and the first Native American Commissioner of the Department of Indian Affairs. His marriage to a much younger socialite scandalized Washington, and he made a fortune on Wall Street and lost it all. He ended his life in genteel poverty, working for nearly 20 years in an obscure position for the New York City Police Department.

For much of American history, women were second-class citizens in the sense they could not vote or run for office and had few property rights. However, women were often able to overcome social restrictions and forcefully affect the world around them, sometimes nationally. This took a real force of character, determination, and sometimes bravery. Women activists focused on issues such as temperance, women’s property rights, improvident or violent husbands, women’s suffrage, cruelty to animals, concern for child labor, and more. This is the story of five such women.
