The Russian Revolution in 1917 was a moment in time when the will of the people put an end to a system of government that had been in place for centuries. The story of Russia’s transition from Imperial reign to eventual Communist dictatorship is a tale rooted in the ranks of the common people and the men who rose to lead them.  

Beginning with the birth of the nation, slavery divided and caused conflict for the United States of America, worsening during the country's early decades as the practice became more economically vital. Finally, in 1861, the American Civil War erupted after the election of President Abraham Lincoln. Never acknowledging the South’s right to secede, Lincoln and the North fought the South through four long, bloody, destructive years; much longer than anyone thought the war would last. 

World War I, or the Great War, was believed to be "the war to end all wars". Because of the incredible extent of destruction and the staggering number of wounded and dead, even those who lived through it could scarcely comprehend its horror. Beginning in 1914, alliances between powerful nations soon plunged the world into a global conflict. Fighting - including miserable trench warfare - broke out in practically every corner of Europe and spread around the world to Africa, Asia, and the Middle East.

Abraham Lincoln's determination to hold the North and South together would ultimately lead to the bloodiest war in American history, the abolition of slavery, and his own untimely death from an assassin’s bullet. But to see Lincoln solely as a tragic figure consumed with the strife of mid-19th century America is to miss meeting him as a man who never allowed himself to be defeated by adversity, grief, or turmoil.

What makes a shooting a massacre? If a mob of hundreds is facing down eight soldiers, and five citizens are killed, is that the Boston Massacre or the Incident on King Street? As was the case with so many of the tumultuous events in America’s colonial history, the answer depended upon whether one regarded oneself as a British subject or a free American. 

Many ancient civilizations are described as mysterious, but none provide as many puzzles and unanswered questions as the Olmecs. These people arrived in lands near the Gulf of Mexico around 1500 BCE and brought with them entirely new concepts in terms of engineering, agriculture, and religion. The problem is we have no idea where they came from or how they developed these new ideas.

George Washington, the first president of the United States, is much more than a monument on Mount Rushmore. Who was Washington, the general, president, and husband? He was first and foremost a man of impeccable honor which, despite military adversity and political wrangling, never abandoned him. The Founding Fathers who squabbled and competed among themselves did agree on one thing: Only Washington could lead the country, first in the country’s military fight for freedom and then as the man charged with transforming 13 individual states into a united country.

In 1812, Americans held two distinctly different visions of their country. These incompatible visions of America were held by two opposing political parties. The two halves of America also had incompatible views on the necessity of war that year.

Over the course of just 200 years, the Ottoman Empire grew from a small, obscure Anatolian state into the most powerful Muslim nation in the world, controlling vast swathes of the Middle East, Eastern Europe, and North Africa. Within the empire, science, medicine, technology, and art flourished, and the Ottoman army became one of the most feared and efficient fighting forces in existence. Then came a period of gradual decline. 

The Cold War between the United States and the Soviet Union lasted from the end of World War II until the end of the 1980s. Over the course of five decades, they never came to blows directly. Rather, these two world superpowers competed in other arenas that would touch almost every corner of the globe. This overview of the Cold War provides the story of how these two countries came to oppose one another and the impact it had on them and others around the world.

Until surprisingly recently, most history books noted that America was discovered in 1492 by Christopher Columbus. The truth was that by the time that Columbus arrived in America, people had been living there for more than 12,000 years. This is the story of the gradual rise, sudden destruction, and slow recovery of the native people of North America.

The story of the Mayflower is one of adventure, courage, and destiny. Leaving England in September of 1620, the ship carried 102 English Separatists to a new life, one that came with the freedom to practice their religious beliefs as they saw fit. These Pilgrims had the courage of their convictions. They had already potentially faced execution for practicing their beliefs, and now they were willing to uproot their lives, their families, and their homes, to sign contracts of indentured servitude - all to find what they called freedom in a foreign land.  

Over a period of more than 10 years, following the overthrow of the government in 1910, Mexico experienced a period of intense and bloody warfare as a bewildering array of factions in ever-changing alliances took power and then lost it. Presidents were elected (or elected themselves) and were then deposed or assassinated. New factions appeared with impressive sounding slogans, took to the field, and were either wiped out and never heard of again or became the next government. 

The Crusades are the prototype and epitome of the Holy War. The fight to take control of the city of Jerusalem, believed to be the most sacred Holy City to two distinct religions of Christianity and Islam, has lasted far longer than the two centuries of the Crusades, and its reach has extended far further than Europe and the Middle East.  

From its beginnings as a loosely definable group of philosophical ideas to the culmination of its revolutionary effect on public life in Europe, the Age of Enlightenment is the defining intellectual and cultural movement of the modern world. Using reason as its core value, the Enlightenment believed that progress and the betterment of the human condition was inevitable.
