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.

The creation of the Union of Soviet Socialist Republics (USSR) in 1922 was one of the defining events of the 20th century. This new federation, created to embody the ideals of communism and the notion of rule by the people, was intended to be different from any other nation in the world. This utopian vision inspired people around the world, and soon, communism became an international movement. However, the history of the Soviet Union did not develop in the way its originators envisaged.

The Spanish Empire was the first truly global empire and the first to be described as one on which “the sun never sets.” It rapidly grew to become one of the largest and most powerful empires in the history of the world and brought us goods such as potatoes, chocolate, and chewing gum.

What would become the nation of Yugoslavia was created in the turbulent period following the end of World War I in 1918, but ended 74 years later in the chaos of another war. In its relatively brief history, Yugoslavia endured invasion during World War II and a range of styles of leadership that included an autocratic king, an even more autocratic socialist dictator, as well as brief periods of parliamentary democracy.

Many of us dream of finding instant wealth. Just imagine if you were able to go to a place where you could simply gather from the ground gold worth many thousands of dollars. Now imagine that at a time when the average wage for an unskilled worker was barely ten dollars per month.

Alan Turing had a radical and ingenious mind. He is considered one of the fathers of artificial intelligence, and his theories on this matter range from purely mechanical to almost spiritual. During World War II, his decryption of the Nazis’ Enigma codes proved vital for the Allied victory over the Axis powers. Turing’s fingerprints are everywhere, and yet his own country for quite some time failed to acknowledge it.

Violent confrontation between armed groups over the supply of illegal narcotics is something we commonly associate with criminal gangs in modern cities, but in the mid-19th century Great Britain went to war with Imperial China in order to continue to supply Chinese addicts with opium. The two wars that followed have become known as the Opium Wars, and they led to the utter defeat of China, the establishment of a British colony in Hong Kong, and the continuation of a narcotics trade that was worth millions of pounds each year to the British.

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.

How could the Jews comprise less than one percent of the world’s population, yet make up 22 percent of Nobel laureates? Despite passing through innumerable challenges, the Jews have produced stunningly gifted people in the sciences, humanities, and economics. Through the millennia and around the world, Jewish history is an astounding story of survival against all odds, yet a touching narrative of faith, covenant, and tradition.

As the 32nd president of the United States of America, Franklin Delano Roosevelt is a common household name in both his home country and the world. Known as the man who led the United States through the Great Depression and World War II, Roosevelt was a leader and a statesman, a scholar, and a politician. Franklin D. Roosevelt is the only president to have served for three consecutive terms and voted in for a fourth, a fact that allows him to stand out among the long list of American presidents.

Based on his early achievements, Aaron Burr, Jr., should have become an obscure but respected figure in American history. An officer in the Continental Army, a high-flying lawyer, and an influential politician, his career peak was becoming the third vice president in US history. But after all these achievements, Burr's name is now associated with corruption and cruelty. He killed a man in an illegal duel while in office, and interest in that man, Alexander Hamilton, has revived Burr's reputation as one of history's villains. Who was Aaron Burr?

The strength and prestige of the American presidency has waxed and waned since George Washington. Accidental Presidents looks at eight men who came to the office without being elected to it. It demonstrates how the character of the man in that powerful seat affects the nation and world.

The extraordinary story of Andrew Jackson—the colorful, dynamic, and forceful president who ushered in the Age of Democracy and set a still young America on its path to greatness—told by the bestselling author of The First American.

The history of the United States displays an uncanny pattern: At moments of crisis, when the odds against success seem overwhelming and disaster looks imminent, fate intervenes to provide deliverance and progress. Historians may categorize these incidents as happy accidents, callous crimes, or the products of brilliant leadership, but the most notable leaders of the past 400 years have identified this good fortune as something else - a reflection of divine providence.

Alexander Hamilton is one of the most extraordinary figures in American history. A deep thinker, a military leader, and a political dynamo, he was George Washington's right-hand man and perhaps the most important figure in the shaping of the Constitution. His policies and practices in government set the United States down a path of commercial wealth and economic stability. His ideas still resonate in the powerful nation he helped create. During his time, Hamilton was a divisive figure.
