What would become the Russian Empire began in the ninth century. In 1682, a new tsar took over the nation that had become known as Russia. Peter I, remembered as Peter the Great, transformed the country, and in 1721, he adopted the title of emperor. A series of powerful rulers, including Catherine the Great, built on the foundations that Peter had created to expand the territory controlled by the Russian Empire until it became one of the largest empires the world had ever seen. At its zenith, the Russian Empire controlled over one-sixth of the total landmass of the Earth

The terrible conflict that dominated the mid-19th century, the Crimean War, killed at least 800,000 men and pitted Russia against a formidable coalition of Britain, France and the Ottoman Empire. It was a war for territory, provoked by fear that if the Ottoman Empire were to collapse then Russia could control a huge swathe of land from the Balkans to the Persian Gulf. But it was also a war of religion, driven by a fervent, populist and ever more ferocious belief by the Tsar and his ministers that it was Russia's task to rule all Orthodox Christians and control the Holy Land.

The Boxer Rebellion saw impoverished Chinese peasants strike a blow against the Western powers, particularly the British, who had come to challenge China’s sovereignty. The uprising was both a harbinger of things to come for China and a by-product of simmering decades of friction between the Chinese and the British. The Chinese had been able to call the shots during the initial engagement of trade with the West, but lost control after the British began smuggling opium into the country.

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.

Barbed wire, trenches, and machine guns are all elements of modern warfare that are mainly associated with the bloody carnage of World War One, yet they were all first used in combination 10 years earlier in a largely forgotten war that was fought in Manchuria and Korea: the Russo-Japanese War.

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.

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.

Whether you approve or disapprove, globalization is an inescapable feature of the modern world. Trade between nations and continents is now commonplace, and this exchange of goods is inevitably accompanied by the exchange of ideas and cultures. This is not, as you might expect, a new phenomenon. A series of trade routes which were first established almost 2,000 years ago provided one of the first examples of intercontinental trade.

The Hittites lived among gods and kings and captivated the mysterious Sir Lawrence of Arabia, among many eager minds. Who were they? Simply warlike conquerors on a mission to impose Hittite power on the world? How did they become part of the elite highly-exclusive club of kings as great as Egyptian, Assyrian, and Babylonian empires of the second millennium BCE? They created a complex system of collective governance and changed the metallurgy of the ancient world. This mysterious empire remained the unknown fourth empire and thanks to their tradition of preservation we continue solving mysteries buried in their ancient past.

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.

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.

During the late years of the 18th century, the spirit of Enlightenment thinking and revolution were in the air. The world was changing, moving away from ingrained beliefs about religion, reason, society, and the rights of the individual and turning more toward the laws of nature as interpreted by the scientific method. Nowhere was the influence of this radical new way of thinking more apparent than in France, and the upheaval this caused would come to bloody fruition in the form of revolution.

The Napoleonic Wars saw fighting on an unprecedented scale in Europe and the Americas. It took the wealth of the British Empire, combined with the might of the continental armies, almost two decades to bring down one of the world's greatest military leaders and the empire that he had created. Napoleon's ultimate defeat was to determine the history of Europe for almost 100 years. From the frozen wastelands of Russia, through the brutal fighting in the Peninsula to the blood-soaked battlefield of Waterloo, this book tells the story of the dramatic rise and fall of the Napoleonic Empire.

The Sumerians settled in the area known as Mesopotamia, between the Tigris and Euphrates Rivers, around 5,000 years ago. They produced many fundamental changes to the way in which human societies developed - these were the first city-builders, the first people to use wheeled vehicles, the first methodical astronomers, and the first people to develop a sophisticated written language. The Sumerians also produced art, music, and literature as well as created some of the first professional soldiers the world had ever seen.

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.
