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.

Apartheid, a state-sponsored policy of discrimination and segregation, was introduced and brutally enforced in South Africa for more than 40 years. It led to thousands of deaths, mass arrests, torture of prisoners, and to the suspension of the most basic human rights for the majority of Black South Africans. How did this come to be, and how did a modern state come to enact and enforce a series of laws deliberately designed to ensure poverty and lack of opportunity for the majority of its population?

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

Constantine the Great was one of the most pivotal figures in the history of the Roman Empire and the widespread expansion of the Christian religion. This is in no way an understatement; Constantine was not only one of the last truly powerful Roman emperors, but he also successfully reconstituted the whole empire according to his vision of Rome’s future. He played the most significant role in transforming the Empire from a Greco-Roman pagan dominion into a bulwark of the Christian faith, granting for the first time real temporal power for the early Christian church.

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 Renaissance, or rebirth, was a period of time when Europeans began to question what they had been told was sacrosanct. Through art, inventions, science, literature, and theology, the separate nations of the European continent sought answers that the Roman Catholic Church was unwilling, or perhaps unable, to offer. It was a triumph of the human spirit and a confirmation of human ability, even as it affirmed the willingness of men and women to die for the right to think freely.

The period from 1870 to 1900 in the US has become known as the Gilded Age, during which America was transformed almost beyond recognition. The Gilded Age was an era of entrepreneurs, inventions, industrial development, and new ideas. Most of all, it was a period of rapid and profound change that came at a high cost for the working class.

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.

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.

Discover the remarkable history of the Crimean War...The Crimean War was one of the bloodiest conflicts of the 19th century, but it is also one of the least remembered. More men died in the Crimean War than in the American Civil War which followed soon after. Yet the Crimean War is important for a number of reasons. Although it did not change the map of Europe and did not directly cause the fall of any of the combatants, it did indirectly shape the second half of the 19th century and the early years of the twentieth century in Europe.

The Great Depression was one of the most trying eras in American history. All aspects of the US were affected. After the stock market crash of 1929, the nation was thrust into a decade of turmoil and change - in government, the economy, and culture. Many of the changes brought about by the Great Depression remain today.

Once valued at close to seven trillion dollars by today’s standards, the Dutch East India Company, formed in 1602, became the world’s first multinational corporation. In the nearly 200-year reign of their empire at sea, the Dutch East India Company amassed unfathomable fortunes, laid the foundation of the modern globalized world, and built monopolies that controlled the economy of the 17th and 18th centuries in Europe and the East Indies.

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.

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.

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.
