In 1307, as they struggled to secure their last strongholds in the Kingdom of Jerusalem, the Templars fell afoul of the vindictive and impulsive king of France. On Friday, October 13, hundreds of brothers were arrested en masse, imprisoned, tortured, and disbanded amid accusations of lurid sexual misconduct and heresy. They were tried by the Vatican in secret proceedings. But were they heretics or victims of a ruthlessly repressive state?

A classic work of military strategy, On War sets forth the theories and tactics of Carl von Clausewitz, a distinguished Prussian general who was notable for his roles in the French Revolutionary and Napoleonic Wars. The book covers a broad range of topics, including weapons, terrain, troops, and leadership, as well as the importance of defense over offence, the balance of power, and the subordination of war to politics. Praised for its timeless insights, Clausewitz’s treatise is often compared to the work of Machiavelli and Sun Tzu, and remains relevant to military leaders.

For over 20 years, a select group of Yale undergraduates has been admitted into the year-long "Grand Strategy" seminar team-taught by John Lewis Gaddis and Paul Kennedy. Its purpose: to provide a grounding in strategic decision-making in the face of crisis to prepare future American leaders for important work. Now, John Lewis Gaddis has transposed the experience of that course into a wonderfully succinct, lucid and inspirational book, a view from the commanding heights of statesmanship across the landscape of world history from the ancient Greeks to Lincoln, and beyond.

Alexander was born into the royal family of Macedonia, the kingdom that would soon rule over Greece. Tutored as a boy by Aristotle, Alexander had an inquisitive mind that would serve him well when he faced formidable obstacles during his military campaigns. Shortly after taking command of the army, he launched an invasion of the Persian Empire, and continued his conquests as far south as the deserts of Egypt and as far east as the mountains of present-day Pakistan and the plains of India.

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.

In Strategy: A History, Sir Lawrence Freedman, one of the world's leading authorities on war and international politics, captures the vast history of strategic thinking, in a consistently engaging and insightful account of how strategy came to pervade every aspect of our lives.

Gates of Fire puts you at the side of valiant Spartan warriors in 480 BC for the bloody, climactic battle at Thermopylae. There, a few hundred of Sparta’s finest sacrificed their lives to hold back the invading Persian millions. The time they bought enabled the Greeks to rally - saving, according to ancient historian Herodotus, “Western democracy and freedom from perishing in the cradle.” How did the Spartans accomplish this superhuman feat? This is what the King of Persia hopes to learn from the sole Spartan survivor.

This classic war memoir, first published in 1920, is based on the author's extensive diaries describing hard combat experienced on the Western Front during World War I. It has been greatly admired by people as diverse as Bertolt Brecht and Andre Gide, and from every part of the political spectrum. Hypnotic, thrilling, and magnificent, The Storm of Steel is perhaps the most fascinating description of modern warfare ever written.

Originally published anonymously, The Federalist Papers first appeared in 1787 as a series of letters to New York newspapers exhorting voters to ratify the proposed Constitution of the United States. Still hotly debated and open to often controversial interpretations, the arguments first presented here by three of America's greatest patriots and political theorists were created during a critical moment in our nation's history.

Many of the world's leaders have turned to Niccolo Machiavelli's The Art of War as a guide to the fundamentals of war, including Frederick the Great, Napoleon, as well as countless other military leaders. Limited warfare is one of the philosophies promoted in this work. Machiavelli believed that military conflict should be a last resort and should only be considered when diplomacy fails. He was also of the belief that society could only remain stable and secure with a strong state military.

More than 2,000 years after his death, Julius Caesar remains one of the great figures of history. He shaped Rome for generations, and his name became a synonym for "emperor" - not only in Rome but as far away as Germany and Russia. He is best known as the general who defeated the Gauls and doubled the size of Rome's territories. But, as Philip Freeman describes in this fascinating new biography, Caesar was also a brilliant orator, an accomplished writer, a skilled politician, and much more.

I have always been a soldier. I have known no other life. So begins Alexander’s extraordinary confession on the eve of his greatest crisis of leadership. By turns heroic and calculating, compassionate and utterly merciless, Alexander recounts with a warrior’s unflinching eye for detail the blood, the terror, and the tactics of his greatest battlefield victories.

Although T. E. Lawrence, commonly known as "Lawrence of Arabia’, died in 1935, the story of his life has captured the imagination of succeeding generations. Seven Pillars of Wisdom is a monumental work in which he chronicles his role in leading the Arab Revolt against the Turks during the First World War. A reluctant leader, and wracked by guilt at the duplicity of the British, Lawrence nevertheless threw himself into his role, suffering the blistering desert conditions and masterminding military campaigns which culminated in the triumphant march of the Arabs into Damascus.

In this, the first prose history in European civilization, Herodotus describes the growth of the Persian Empire with force, authority, and style. Perhaps most famously, the book tells the heroic tale of the Greeks' resistance to the vast invading force assembled by Xerxes, king of Persia. Here are not only the great battles - Marathon, Thermopylae, and Salamis - but also penetrating human insight and a powerful sense of epic destiny at work.

Seeking to depose his brother Artaxerxes and take his place upon the Persian throne, Cyrus the Younger leads the 10,000 mercenaries on a dangerous campaign deep into the heart of Persia. There, Cyrus is killed and his generals overthrown, leaving a young Xenophon to lead the army on its treacherous journey home. Snowy mountains, wide rivers, violent blizzards, and hostile tribes obstruct their way, testing Xenophon's leadership and his soldiers' perseverance to the extreme.

The Hellenica is Xenophon’s continuation of Thucydides’ history of the Peloponnesian War, literally resuming from where the previous author’s history was abruptly left unfinished and narrating the events of the final seven years of the conflict and the war’s aftermath. Some historians consider the Hellenica to be a personal work, written by Xenophon in retirement on his Spartan estate, and intended primarily for circulation among his friends, who would have known the main protagonists and events, having most likely participated in them.

In Alexander the Great, Anthony Everitt judges Alexander’s life against the criteria of his own age and considers all his contradictions. We meet the Macedonian prince who was naturally inquisitive and fascinated by science and exploration, as well as the man who enjoyed the arts and used Homer’s great epic, the Iliad, as a bible. As his empire grew, Alexander exhibited respect for the traditions of his new subjects and careful judgment in administering rule over his vast territory. But his career also had a dark side.

In this, the first prose history in European civilization, Herodotus describes the growth of the Persian Empire with force, authority, and style. Perhaps most famously, the book tells the heroic tale of the Greeks' resistance to the vast invading force assembled by Xerxes, king of Persia. Here are not only the great battles - Marathon, Thermopylae, and Salamis - but also penetrating human insight and a powerful sense of epic destiny at work.

At the bloody battle of Cannae, he trounced a Roman army twice the size of his own. With his brothers, he subdued nearly all of Italy, Spain and Northern Africa. A cunning tactician, he secured victory for Bithynia at sea by catapulting poisonous snakes onto the decks of his enemy’s ships. Biographer Ernle Bradford draws on the historical writings of Livy, Polybius, Plutarch and others in re-creating the fantastic story of the greatest general since Alexander the Great.

Hannibal is often considered the finest general the world has ever known. Setting out from Carthaginian-dominated Spain with a small army of select troops, he fought his way over the Pyrenees and crossed the Alps with elephants and a full baggage train. Descending into Italy, he destroyed the main Roman army at Lake Trasimeno and came close to conquering Rome itself.

Harald Sigurdsson burst into history as a teenaged youth in a Viking battle from which he escaped with little more than his life and a thirst for vengeance. But from these humble origins, he became one of Norway’s most legendary kings. The Last Viking is a fast-moving narrative account of the life of King Harald Hardrada, as he journeyed across the medieval world, from the frozen wastelands of the North to the glittering towers of Byzantium and the passions of the Holy Land, until his warrior death on the battlefield in England.

This definitive biography of one of history's most influential father-son duos tells the story of two rulers who gripped the world - and their rise and fall from power.

Hilaire Belloc (1870-1953) - one of the most prominent Catholic authors of his time - gives a common-sense explanation of why the Crusades were necessary and why they ultimately failed. Writing in 1937, following the demise of the Ottoman Empire, Belloc believed that the West had finally gained the advantage over its mortal foe; however, he also includes a prophetic warning concerning the eventual resurgence of Islam and its enduring desire to destroy Christendom.

In The Accursed Tower, Roger Crowley delivers a lively narrative of the lead-up to the siege and a vivid, blow-by-blow account of the climactic battle. Drawing on extant Arabic sources as well as untranslated Latin documents, he argues that Acre is notable for technical advances in military planning and siege warfare, and extraordinary for its individual heroism and savage slaughter. A gripping depiction of the crusader era told through its dramatic last moments, The Accursed Tower offers an essential new view on a crucial turning point in world history.

In this stirring tale of the last days of the Temple at Jerusalem, robber bands and political infighting set the stage for the Roman destruction of the city in 70 A.D. In the face of overwhelming odds, John of Gamala does his best to save God's Temple, harassing Roman work parties, burning Roman camps, defending Jerusalem during the Roman siege, and even fighting Titus himself in hand-to-hand combat, forging a relationship with the Roman leader that lasts until after the war.

The Spanish Conquest: What really happened? If you like to use your drive time for education by audiobook, consider this audiobook for widening and deepening your view of an event you studied briefly in school - the Spanish conquest of the Americas. Conquistador Voices, neither glamorizes nor condemns the conquistadors. Somewhat in the manner of a modern film documentary, it treats the so-called conquest as an historical event that’s worth learning about for its own sake, with most of the moralizing left to the listener.

For the first time, By the Spear offers an exhilarating military narrative of the reigns of these two larger-than-life figures in one volume. Ian Worthington gives full breadth to the careers of father and son, showing how Philip was the architect of the Macedonian empire, which reached its zenith under Alexander, only to disintegrate upon his death.

Julius Caesar was nothing if not bold. When, in the wake of his defeat of Pompey at Pharsalus his victorious legions refused to march another step under his command, he pursued his fleeing rival into Egypt with an impossibly small force of Gallic and German cavalry, raw Italian recruits, and nine hundred Spanish prisoners of war - tough veterans of Pompey's Sixth Legion. Cleopatra's Kidnappers tells the epic saga of Caesar's adventures in Egypt through the eyes of these captured, but never defeated, legionaries.

In Gladius, Guy de la Bedoyere takes us straight to the heart of what it meant to be a part of the Roman army. Rather than a history of the army itself, or a guide to military organization and fighting methods, this book is a ground-level recreation of what it was like to be a soldier in the army that made the empire. Surveying numerous aspects of life in the Roman army between 264 BCE and 337 CE, Gladius draws not only on the words of famed Roman historians, but also those of the soldiers themselves.

Historians universally agree that Thucydides was the greatest historian who has ever lived, and that his story of the Peloponnesian conflict is a marvel of forensic science and fine literature. That such a triumph of intellectual accomplishment was created at the end of the fifth century B.C. in Greece is, perhaps, not so surprising, given the number of original geniuses we find in that period. But that such an historical work would also be simultaneously acknowledged as a work of great literature and a penetrating ethical evaluation of humanity is one of the miracles of ancient history.
