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.

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.

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.

Americans have long been fascinated by the Civil War, marveling at the size of the battles, the leadership of the generals, and the courage of the soldiers. The Civil War was the deadliest conflict in American history, and had the two sides realized it would take four years and inflict over a million casualties, it might not have been fought. Since it did, however, historians and history buffs alike have been studying and analyzing the military and political history of the conflict ever since.

England has more often been faced with the claims of competing kings and queens than with a period of no monarch at all. The major exception to that rule came in the 11 years between 1649 and 1660, when England was a republic. Following the disastrous reign of Charles I and the civil wars that led to his execution, Parliament and the army ruled England. England’s republican experiment started out as a work of collaboration and compromise; lords, army officers, and members of Parliament (MPs) worked together to find a political settlement.

As Union commander George McClellan moved the Army of the Potomac up the Peninsula in early 1862, the Union army still had a nearly 2-1 advantage in manpower, so Army of Northern Virginia commander Joseph E. Johnston continued to gradually pull his troops back to a line of defense nearer Richmond as McClellan advanced. In conjunction, the Union Navy began moving its operations further up the James River, until it could get within seven miles of the Confederate capital before being opposed by a Southern fort.

"We, conquered by William, have liberated the Conqueror’s land." So reads the memorial to the British war dead at Bayeaux, Normandy. Commemorating those who gave their lives to free France in 1944, it also serves to remind us of an earlier conflict. For the English, the Norman conquest remains deeply embedded in the national psyche. As the last contested military invasion to have succeeded in conquering this proud island nation, the date of 1066 is the one every citizen can remember.

The Underground Railroad is one of the most taught topics to young schoolchildren, and every American is familiar with the idea of fugitive slaves escaping to Canada and the North with the help of determined abolitionists and even former escaped slaves like Harriet Tubman. The secrecy involved in the Underground Railroad made it one of the most mysterious aspects of the mid-19th century in America, to the extent that claims spread that 100,000 slaves had escaped via the Underground Railroad.

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.

India has been the location of many different empires throughout its long history. The Indus Valley Civilization was home to one of the world’s first civilizations more than 5,000 years ago, which was followed by the Aryan-Vedic culture and then a host of other kingdoms that flourished across the subcontinent. India has also been the birthplace of many religions. The Vedic religion of the Aryans evolved into the Hindu religion, and Buddhism and Jainism were also born in India. By the Middle Ages, India was home to many different religions and ethnic groups.

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. What humans commonly refer to as the “Ice Age” is actually a series of fluctuating climate events that have occurred throughout the planet’s history. These ongoing historical phenomena are difficult to conceptualize because of both the time frame involved and the natural process by which they cyclically unfold.

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.

When scholars study the history of the ancient Near East, several wars that had extremely brutal consequences (at least by modern standards) often stand out. Forced removal of entire populations, sieges that decimated entire cities, and wanton destruction of property were all tactics used by the various peoples of the ancient Near East against each other, but the Assyrians were the first people to make war a science. When the Assyrians are mentioned, images of war and brutality are among the first that come to mind, despite the fact that their culture prospered for nearly 2,000 years.

When England’s King Edward IV fell ill at Easter 1483 after coming back from a fishing trip and died shortly after on April 9, it threw a country that had already suffered a series of wars into a state of chaos. What exactly killed him is unclear, and though some people would later speculate that he had been poisoned, there is every reason to believe that he died of natural causes. Disease was common in medieval England, and doctors lacked much of the medical knowledge now taken for granted.

Throughout the history of warfare, the practice of placing blame on innocent parties in order to justify attacking them has been a constant feature. In the 20th century, this practice began to be commonly referred to as a “false flag” operation. The essence of a false flag scenario is that it is conducted by one party or government and “made to appear as though another party sponsored it".

The conflict between the Israelis and Palestinians is technically over 70 years old and counting but has its roots in over 2,000 years of history. With so much time and history, the Middle East peace process has become laden with unique, politically sensitive concepts like the right of return, contiguous borders, secure borders, demilitarized zones, and security requirements, with players like the Quartet, Palestinian Authority, Fatah, Hamas, the Arab League and Israel.

Salty People is an eye-opening narrative about moving beyond those who are envious of you, forgiving and finding peace with your past, appreciating the haters in life, and using these experiences as motivation to become the best version of yourself. In this humorous and profoundly relatable book, communication expert Charles Rivers emphasizes how the salty people in our lives work to inspire our dreams more than kind words would. Once we understand who strengthens us and weakens us, we can become more successful.

The Underground Railroad is one of the most taught topics to young schoolchildren, and every American is familiar with the idea of fugitive slaves escaping to Canada and the North with the help of determined abolitionists and even former escaped slaves like Harriet Tubman. There were also slaves who ran and hid out, or who made their own settlements, who were called maroons. Some escapees joined together to establish lasting settlements in inaccessible areas in mountains and swamps, sometimes preferring death rather than being caught and enslaved again. Others hid temporarily.

For the people of the ancient Mediterranean and beyond, the city of Rome had been a symbol of power for centuries, and entering the early 5th century CE, the Eternal City hadn’t been taken by an enemy force since the Gauls had done it about 800 years, an unheard of period of tranquility in a world wracked with almost constant warfare. Thus, when the Visigoths, whom the Romans considered uncultured and inferior, took the city of Rome and sacked it in 410, the world was stunned. It made theologians of the newly Christianized empire question God’s plan on Earth.
