Until 1939, World War I was known as “the war to end all wars”, but when Nazi Germany capped its mounting aggression against its neighbors by invading Poland, Europe was plunged into a second global conflict. It threatened the entire continent as well as the far-flung colonial possessions claimed by the French, the British, and the Dutch. German triumphs saw nation after nation fall, until only Great Britain remained defiant against Hitler’s dreams of conquest.

The narrative of the Korean War in the West, and particularly in the United States, tells the tale of a conflict between two global superpowers and competing ideologies in a far-flung corner of the globe. The reality is that the wheels of motion that drove the country to war in 1950 began turning long before American boots set foot on Korean soil. The heart of the conflict was a civil war between a population arbitrarily divided by colonization and the global geopolitics at the end of the Second World War.

D-Day, June 6, is one of the most significant dates in the calendar. The 20th century's fate hung in the balance as Nazi Germany had marched across Europe, bringing the blitzkrieg, the Holocaust, and the mad dreams of Adolf Hitler across the bloodied landscape of Europe. In order for the Nazis to be stopped, the Allies had to invade occupied Europe. And invade they did, launching the most massive amphibious landing the world had ever seen.

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 Mongol Empire, founded by Genghis Khan and continued by his heirs, was one of the largest and most powerful the world has ever seen. Modern China was created from the remnants of the Mongol Empire, and at its peak, this empire controlled one-sixth of the total landmass of the world. Even today, it is estimated that one in every 200 people in the world carries the DNA of Genghis Khan. The world would never be quite the same after the relatively brief reign of Genghis Khan, his children, and grandchildren.

The Spanish Civil War was much more than just an overture to World War II. It was a war born out of schisms in Spanish society between rich and poor, monarchists and Republicans, the right and the left, and between those who supported the church and those who saw it as an instrument of oppression. For all its brutality and horror, the Spanish Civil War was a conflict between ideals often fought by volunteers on each side who truly believed that they were helping to build a better world.

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 Vietnam War remains one of the most iconic events of the 20th century. In the United States, it polarized public opinion and changed foreign policy. It destroyed the presidency of Lyndon Johnson and was the catalyst for a massively impactful protest movement. More importantly, in Vietnam, as well as surrounding areas, it caused untold destruction, death, and suffering.

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.

Auschwitz is a monument to the barbaric inhumanity of the Nazi regime. It is the site where more than one million people were systematically tortured and killed in support of Adolf Hitler’s determination to eradicate entire populations that he viewed as racially impure.

The most notorious man in history, Adolf Hitler, is best known for having perpetrated crimes against humanity over the six-year course of World War II. His brutal extermination policies are responsible for the deaths of close to 30 million people he considered inferior, and added to that, the military casualties suffered by all parties, yields a grand total of approximately 60 million people dead by the end of the war. That number equates to 3% of the world's population at the time. But, who was this man? What made him into the monster he became? Can his childhood explain the formation of such a brutal dictator?

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.

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.

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 saga of the Vikings rises and falls on the banks of history, ebbing and flowing with popular opinion and whimsical anecdotes. The Vikings are routinely typecast and labeled anywhere from bloodthirsty tyrants to valiant heroes. They have been condemned as pirates and praised as explorers. We have all heard the stories of the fierce warriors with long ships and horned helmets storming onto the shores of medieval Europe - but who were these men really?

If you want to discover the captivating history of the Peloponnesian War, then pay attention. The Peloponnesian War enveloped the entire Greek world, from Syracuse on the island of Sicily to the shores of western Turkey. It ravaged the Greek population and produced great hardships, and it led to the eventual downfall of the Athenian Empire and the rise of the Spartan Empire.

Germany is one of the richest and most influential countries in the world, which is amazing when you consider that the nation is only about the size of the US states of Oregon and Washington combined. It’s even more astounding when you consider that at the end of World War II, every major German city (and many minor ones) had been flattened by the Allied bombing campaign. Still more amazing is that the country has gone from international pariah and home of the Holocaust to one of the most well-regarded and humanitarian nations on Earth.

The narrative of the Korean War in the West, and particularly in the United States, tells the tale of a conflict between two global superpowers and competing ideologies in a far-flung corner of the globe.

For decades, a major piece of World War II history has gone virtually unwritten. The war began in China two full years before Hitler invaded Poland, and China eventually became the fourth great ally, partner to the United States, the Soviet Union, and Great Britain. Yet its drama of invasion, resistance, slaughter, and political intrigue remains little known in the West.

In The Vanquished, a highly original and gripping work of history, Robert Gerwarth asks us to think again about the true legacy of the First World War. In large part it was not the fighting on the Western Front that proved so ruinous to Europe's future but the devastating aftermath, as countries on both sides of the original conflict were savaged by revolutions, pogroms, mass expulsions, and further major military clashes.

The Great War of 1914-1918 was the first mass conflict to fully mobilize the resources of industrial powers against one another, resulting in a brutal, bloody, protracted war of attrition between the world's great economies. Now, 100 years after the first guns of August rang out on the Western front, historian William Philpott reexamines the causes and lingering effects of the first truly modern war.

In this monumental history of the First World War, Germany's leading historian of the 20th century's first great catastrophe explains the war's origins, course, and consequences. With an unrivaled combination of depth and global reach, Pandora's Box reveals how profoundly the war shaped the world to come. Jörn Leonhard treats the clash of arms with a sure feel for grand strategy, the everyday tactics of dynamic movement and slow attrition, the race for ever more destructive technologies, and the grim experiences of frontline soldiers.

Hailed as a "pithy and compelling account of an intensely relevant topic" ( Kirkus Reviews), this wide-ranging volume offers a superb account of a key moment in modern U.S. and world history. Drawing upon the latest research in archives in China, Russia, and Vietnam, Mark Lawrence creates an extraordinary, panoramic view of all sides of the war.

A decade after the cold war ended, policy makers and academics foresaw a new era of peace and prosperity, an era in which democracy and open trade would herald the "end of history." The terrorist attacks of September 11, 2001, sadly shattered these idyllic illusions, and John Mearsheimer's masterful new book explains why these harmonious visions remain utopian.

Ukraine is a geographically diverse country with the unfortunate fate of being sandwiched between empires. Though this is frequently explored no further than the global conflicts of the 20th century, in reality, Ukraine’s struggle for self-determination has far deeper roots than most people realize. See the splendor of the Kyivan Rus, gallop with the Golden Horde across the Ukrainian steppe, encounter the legendary Cossacks, and witness the terror of the tsars. From the Romans to the Mongols to the Russians, Ukraine has seen it all and remained uniquely Ukrainian through it all.

History for busy people. Listen to a concise history of World War One in just one hour. World War One brought with it the world’s first experience of Total War, involving all of the world’s great powers, polarized between the Triple Entente, led by Britain, France and Russia, and the Central Powers, dominated by Germany, Italy and Austria-Hungary. Around nine million men lost their lives in a conflict that introduced the horrors of trench warfare, machine guns, and toxic gas attacks.

In this definitive history of the modern Arab world, award-winning historian Eugene Rogan draws extensively on Arab sources and texts to place the Arab experience in its crucial historical context for the first time. Tracing five centuries of Arab history, Rogan reveals that there was an age when the Arabs set the rules for the rest of the world. Today, however, the Arab world's sense of subjection to external powers carries vast consequences for both the region and Westerners who attempt to control it.

Local resistance to German-led Axis occupation occurred throughout the European continent during World War II, taking a wide range of forms - noncooperation and disinformation, sabotage and espionage, and armed opposition and full-scale partisan warfare. It is a key element in the experience and the national memory of those who found themselves under Axis government and control.

George Washington’s military strategy has been called bumbling at worst and brilliant at best. So which is it? Was George Washington a strategic genius or just lucky? So asks Dave R. Palmer in George Washington’s Military Genius. An updated edition of Palmer’s earlier work, The Way of the Fox, George Washington’s Military Genius breaks down the American Revolution into four phases and analyzes Washington’s strategy during each.

On a summer day in 1914, a nineteen-year-old Serbian nationalist gunned down Archduke Franz Ferdinand in Sarajevo. While the world slumbered, monumental forces were shaken. In less than a month, a combination of ambition, deceit, fear, jealousy, missed opportunities, and miscalculation sent Austro-Hungarian troops marching into Serbia, German troops streaming toward Paris, and a vast Russian army into war, with England as its ally. As crowds cheered their armies on, no one could guess what lay ahead in the First World War.

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.

The Progressive Era was the period of American history between the 1890s and 1920s. It was a movement dedicated to political and social reform, largely driven by the middle class. In a world that was dominated by wealthy industrialists and threatened by radical ideas of laborers, the middle class strived for order.
