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.
