The Mongol army led by Genghis Khan subjugated more lands and people in 25 years than the Romans did in 400. In nearly every country the Mongols conquered, they brought an unprecedented rise in cultural communication, expanded trade, and a blossoming of civilization.

The Roman Republic was one of the most remarkable achievements in the history of civilization. After its founding in 509 BCE, the Romans refused to allow a single leader to seize control of the state and grab absolute power. The Roman commitment to cooperative government and peaceful transfers of power was unmatched in the history of the ancient world. But by the year 133 BCE, the republican system was unable to cope with the vast empire Rome now ruled.

Few historical events are as greatly revered and entirely misunderstood as the French Revolution that began in 1789. The memory of this complicated and lengthy political, violent uprising has been generally painted in broad - and oversimplified - strokes. While the French Revolution was certainly centered around two lavish monarchs and an enlightened common class, there was so much more going on behind the scenes.

Robert Tombs' momentous The English and Their History is both a startlingly fresh and a uniquely inclusive account of the people who have a claim to be the oldest nation in the world. The English first came into existence as an idea, before they had a common ruler and before the country they lived in even had a name. They have lasted as a recognizable entity ever since, and their defining national institutions can be traced back to the earliest years of their history.

Initially presiding over an oligarchic one-party regime that governed by plurality, Joseph Stalin became the de facto dictator of the Soviet Union. Stalin raised funds for Vladimir Lenin's Bolshevik faction via robberies, kidnappings, and protection rackets. To eradicate those regarded as "enemies of the working class", Stalin instituted the "Great Purge" in which more than a million were imprisoned and at least 700,000 were executed from 1934 to 1939.

Since its beginnings, Poland has been a moving target, geographically as well as demographically, and the very definition of who is a Pole has been in flux. In the late medieval and early modern periods, the country grew to be the largest in continental Europe, only to be later wiped off the map for more than a century. Yet even under these constraints, Poles persisted in their desire to wrest from their oppressors a modicum of national dignity and, ultimately, managed to achieve much more than that.

Chris Harman describes the shape and course of human history as a narrative of ordinary people forming and re-forming complex societies in pursuit of common human goals. Interacting with the forces of technological change as well as the impact of powerful individuals and revolutionary ideas, these societies have engendered events familiar to every schoolchild-from the empires of antiquity to the world wars of the 20th century. In a bravura conclusion, Chris Harman exposes the reductive complacency of contemporary capitalism.

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.

Emigration of people from Sicily often overshadows the importance of the people who immigrated to the island through the centuries. These have included several who became Sicily's rulers, along with Jews, Ligurians, and Albanians. Greeks, Romans, Vandals, Goths, Byzantines, Muslims, Normans, Hohenstaufens, Spaniards, Bourbons, the Savoy Kingdom of Italy and the modern era have all held sway, and left lasting influences on the island's culture and architecture.

The Story of Russia is about how the Russians defined themselves―and repeatedly reinvented such definitions along the way. Moving from Russia’s agrarian beginnings in the first millennium to subsequent periods of monarchy, totalitarianism, and perestroika, all the way up to Vladimir Putin and his use of myths of Russian history to bolster his regime, celebrated historian Orlando Figes examines the ideas that have guided the country’s actions.

Starting in early 1915, the Ottoman Turks began deporting and killing hundreds of thousands of Armenians in the first major genocide of the 20th century. By the end of the First World War, the number of Armenians in what would become Turkey had been reduced by 90 percent - more than 1,000,000 people. A century later, the Armenian genocide remains controversial but relatively unknown, overshadowed by later slaughters and the chasm separating Turkish and Armenian versions of events.

In Mortal Republic, prize-winning historian Edward J. Watts offers a new history of the fall of the Roman Republic that explains why Rome exchanged freedom for autocracy. For centuries, even as Rome grew into the Mediterranean's premier military and political power, its governing institutions, parliamentary rules, and political customs successfully fostered negotiation and compromise. By the 130s BC, however, Rome's leaders increasingly used these same tools to cynically pursue individual gain and obstruct their opponents.

Denmark, Finland, Norway, and Sweden, award-winning historian Ewan Butler writes, struggled through unions and separations with both outsiders and each other, developing their own personalities and languages yet retaining their ancient connections.

T. R. Fehrenbach brilliantly delineates the contrasts and conflicts between the many Mexicos, unraveling the history while weaving a fascinating tapestry of beauty and brutality: the Amerindians, who wrought from the vulnerable land a great indigenous Meso-American civilization by the first millennium BC; the successive reigns of Olmec, Maya, Toltec, and Mexic masters, who ruled through an admirably efficient bureaucracy and the power of the priests, propitiating the capricious gods with human sacrifices; the Spanish conquistadors, and much more.

Because of our shared English language, as well as the celebrated origin tales of the Mayflower and the rebellion of the British colonies, the United States has prized its Anglo heritage above all others. However, as Carrie Gibson explains with great depth and clarity in El Norte, the nation has much older Spanish roots - ones that have long been unacknowledged or marginalized. The Hispanic past of the United States predates the arrival of the Pilgrims by a century, and has been every bit as important in shaping the nation as it exists today.
