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.

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

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.

Rome is a city of myth and legend. The Eternal City, the city of the seven hills, the sacred city, the caput mundi, the center of the world, Roma, Rome, by any of her many names is a city built of history and blood, marble and water, war and conquest. From legendary beginnings, a city rose from the swamp surrounded by the seven hills and split by the Tiber River. Built and rebuilt, a sacred republic and a divine empire, blessed by a thousand gods and by One, the story of her rise and fall has been told and retold for a thousand years and is still relevant in today's world, as echoes of her ancient glory have shaped our culture, laws, lifestyle, and beliefs in subtle and pervasive ways.

Nikita Khrushchev came to power in the aftermath of the notorious Soviet dictator Joseph Stalin’s death. Although Khrushchev came on the scene with aggression and fury (the world would never forget how he declared that he would bury the West), he was ultimately a much more peaceful Soviet leader than Stalin ever was. Even when the Cold War was at its most dangerous point during the Cuban Missile Crisis, it was, in many ways, the measured restraint of Khrushchev which helped to avoid unleashing nuclear Armageddon.

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 State of Israel was founded in conflict, and in the first ten years of its existence, it was involved in two major wars with its Arab neighbors. The First Arab-Israeli War began almost the moment that the new state was announced in May 1948. Although it barely had time to create armed forces, somehow Israel survived a simultaneous invasion by armies from four Arab states during that conflict. In 1956, Israel found itself at war again, this time fighting alongside Britain and France, who had launched an invasion of Egypt after fears that the Suez Canal might be closed.

Many of the city-states of Ancient Greece gave the world a legacy rich in art, literature, poetry, philosophy, and science. But one such state distinguished itself by embracing something very different: a warrior lifestyle, a denial of luxury and wealth, and a focus on the collective rather than the individual. While most other Ancient Greek city-states have been forgotten, the name of that city remains in use in the English language today, meaning austere or rigorous: Spartan.

Peaky Blinders is a popular BBC television series about an organized crime family in post-World War I Birmingham, England, but does this series depict the factual history of Birmingham? As it turns out, there were Peaky Blinders in Birmingham, and they terrorized those streets long before World War I.  The Peaky Blinders rose to prominence in the overcrowded and unsanitary conditions of late Victorian Birmingham in the 1870s. Their ranks were composed of the working poor.

In the midst of World War I, the Easter Rising took place in Dublin and throughout Ireland in April 1916. The revolutionary movement faced many problems from the beginning, including splintered leadership, disorganized support, opposition from moderate supporters of home rule, and prepared retaliation from the British.  

Kosovo is a tiny land-locked nation located in the heart of the Balkan Peninsula in Eastern Europe. Before the 1990s, few people outside the immediate area had ever even heard of Kosovo. Then, in 1998, war began, and Kosovo moved to the center of the international stage.

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. 

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.

During the bitter winter of 1692/93, a group of young Puritan women in the colonial town of Salem, Massachusetts, accused more than 200 of their neighbors and fellow townspeople of using witchcraft to injure and torment them. This was an incredibly serious allegation that led to sensational court proceedings and ended with the execution of 19 people.

Discover the remarkable history of the Napoleonic Wars. The Napoleonic Wars were a series of conflicts fought between France and various coalitions in Europe between 1803 and 1815 (though some put the start date at 1799). The prelude to the rise of Napoleon Bonaparte and the Napoleonic Wars is the French Revolution, and the conflicts that continued after Napoleon seized power would radically affect Europe and indeed political philosophies not confined by artificial boundaries.
