    Jonathan Phillips traces the origins, expansion, decline, and conclusion of the Crusades and comments on their contemporary echoes—from the mysteries of the Templars to the grim reality of al-Qaeda. Holy Warriors puts the past in a new perspective and brilliantly sheds light on the origins of today’s wars.Starting with Pope Urban II’s emotive, groundbreaking speech in November 1095, in which he called for the recovery of Jerusalem from Islam by the First Crusade, Phillips traces the centuries-long conflict between two of the world’s great faiths. Using songs, sermons, narratives, and letters of the period, he reveals how the success of the First Crusade inspired generations of kings to campaign for their own vainglory and set down a marker for the knights of Europe, men who increasingly blurred the boundaries between chivalry and crusading. In the Muslim world, early attempts to call a jihad fell upon deaf ears until the charisma of the Sultan Saladin brought the struggle to a climax. Yet the story that emerges has other dimensions—as never before, Phillips incorporates the holy wars within the story of medieval Christendom and Islam and shines new light on many truces, alliances, and diplomatic efforts that have been forgotten over the centuries.Holy Warriors also discusses how the term “crusade” survived into the modern era and how its redefinition through romantic literature and the drive for colonial empires during the nineteenth century gave it an energy and a resonance that persisted down to the alliance between Franco and the Church during the Spanish Civil War and right up to George W. Bush’s pious “war on terror.”Elegantly written, compulsively readable, and full of stunning new portraits of unforgettable real-life figures—from Richard the Lionhearted to Melisende, the formidable crusader queen of Jerusalem—Holy Warriors is a must-read for anyone interested in medieval Europe, as well as for those seeking to understand the history of religious conflict.

    But what if the First Crusade s real catalyst lay far to the east of Rome? In this groundbreaking book, countering nearly a millennium of scholarship, Peter Frankopan reveals the untold history of the First Crusade.Nearly all historians of the First Crusade focus on the papacy and its willing warriors in the West, along with innumerable popular tales of bravery, tragedy, and resilience. In sharp contrast, Frankopan examines events from the East, in particular from Constantinople, seat of the Christian Byzantine Empire. The result is revelatory. The true instigator of the First Crusade, we see, was the Emperor Alexios I Komnenos, who in 1095, with his realm under siege from the Turks and on the point of collapse, begged the pope for military support.Basing his account on long-ignored eastern sources, Frankopan also gives a provocative and highly original explanation of the world-changing events that followed the First Crusade. The Vatican s victory cemented papal power, while Constantinople, the heart of the still-vital Byzantine Empire, never recovered. As a result, both Alexios and Byzantium were consigned to the margins of history. From Frankopan s revolutionary work, we gain a more faithful understanding of the way the taking of Jerusalem set the stage for western Europe s dominance up to the present day and shaped the modern world."

    In handsomely crafted prose, and with the grace and authority of his extraordinary gift for narrative history, William Manchester leads us from a civilization tottering on the brink of collapse to the grandeur of its rebirth - the dense explosion of energy that spawned some of history's greatest poets, philosophers, painters, adventurers, and reformers, as well as some of its most spectacular villains - the Renaissance.

    Norwich presents such popes as Innocent I, who in the fifth century successfully negotiated with Alaric the Goth, an invader civil authorities could not defeat; Leo I, who two decades later tamed (and perhaps paid off) Attila the Hun; the infamous “pornocracy”—the five libertines who were descendants or lovers of Marozia, debauched daughter of one of Rome’s most powerful families; Pope Paul III, “the greatest pontiff of the sixteenth century,” who reinterpreted the Church’s teaching and discipline; John XXIII, who in five short years starting in 1958 instituted reforms that led to Vatican II; and Benedict XVI, who is coping with today’s global priest sex scandal.

    Far from being meek and mild, they were violent, ruthless and fundamentally intolerant. Unlike the polytheistic world, in which the addition of one new religion made no fundamental difference to the old ones, this new ideology stated not only that it was the way, the truth and the light but that, by extension, every single other way was wrong and had to be destroyed. From the 1st century to the 6th, those who didn't fall into step with its beliefs were pursued in every possible way: social, legal, financial and physical. Their altars were upturned and their temples demolished, their statues hacked to pieces and their priests killed. It was an annihilation.Authoritative, vividly written and utterly compelling, this is a remarkable debut from a brilliant young historian.

    Newly revised in the light of the recent developments in Baltic and Northern medieval research, this authoritative overview provides a balanced and compelling account of a tumultuous era.

    Roger Crowley's readable and comprehensive account of the battle between Mehmed II, sultan of the Ottoman Empire, and Constantine XI, the 57th emperor of Byzantium, illuminates the period in history that was a precursor to the current jihad between the West and the Middle East.

    His name was Peter Morrone, a hermit, a founder of a religious order, and, depending on whom you talk to, a reformer, an instigator, a prophet, a coward, a saint, and possibly the victim of murder. A stroke of fate would, practically overnight, transform this humble servant of God into the most powerful man in the Catholic Church. Half a year later, he would be the only pope in history to abdicate the chair of St. Peter, an act that nearly brought the papacy to its knees. What led him to make that decision and what happened afterward would be shrouded in mystery for centuries. The Pope Who Quit pulls back the veil of secrecy on this dramatic time in history and showcases a story that involves deadly dealings, apocalyptic maneuverings, and papal intrigue.

    Stark, the author of The Rise of Christianity, reviews the history of the seven major crusades from 1095-1291 in this fascinating work of religious revisionist history.

    An invasion force on a scale not seen since the days of the Romans. One of the bloodiest and most decisive battles ever fought. This riveting book explains why the Norman Conquest was the single most important event in English history.Assessing the original evidence at every turn, Marc Morris goes beyond the familiar outline to explain why England was at once so powerful and yet so vulnerable to William the Conqueror's attack. Why the Normans, in some respects less sophisticated, possessed the military cutting edge. How William's hopes of a united Anglo-Norman realm unravelled, dashed by English rebellions, Viking invasions and the insatiable demands of his fellow conquerors. This is a tale of powerful drama, repression and seismic social change: the Battle of Hastings itself and the violent 'Harrying of the North'; the sudden introduction of castles and the wholesale rebuilding of every major church; the total destruction of an ancient ruling class. Language, law, architecture, even attitudes towards life itself were altered forever by the coming of the Normans. Marc Morris, author of the bestselling biography of Edward I, A Great and Terrible King, approaches the Conquest with the same passion, verve and scrupulous concern for historical accuracy. This is the definitive account for our times of an extraordinary story, a pivotal moment in the shaping of the English nation.

    The adjective 'medieval' has become a synonym for brutality and uncivilized behavior. Yet without the work of medieval scholars there could have been no Galileo, no Newton and no Scientific Revolution. In God's Philosophers, James Hannam debunks many of the myths about the Middle Ages, showing that medieval people did not think the earth is flat, nor did Columbus 'prove' that it is a sphere; the Inquisition burnt nobody for their science nor was Copernicus afraid of persecution; no Pope tried to ban human dissection or the number zero. God's Philosophers is a celebration of the forgotten scientific achievements of the Middle Ages - advances which were often made thanks to, rather than in spite of, the influence of Christianity and Islam. Decisive progress was also made in technology: spectacles and the mechanical clock, for instance, were both invented in thirteenth-century Europe. Charting an epic journey through six centuries of history, God's Philosophers brings back to light the discoveries of neglected geniuses like John Buridan, Nicole Oresme and Thomas Bradwardine, as well as putting into context the contributions of more familiar figures like Roger Bacon, William of Ockham and Saint Thomas Aquinas.

    Acclaimed as the definitive account of these epochal events, Diarmaid MacCulloch's award-winning history brilliantly recreates the religious battles of priests, monarchs, scholars, and politicians--from the zealous Martin Luther and his Ninety-Five Theses to the polemical John Calvin to the radical Igantius Loyola, from the tortured Thomas Cranmer to the ambitious Philip II. Drawing together the many strands of the Reformation and Counter-Reformation, and ranging widely across Europe and the New World, MacCulloch reveals as never before how these dramatic upheavals affected everyday lives--overturning ideas of love, sex, death, and the supernatural, and shaping the modern age.

    For much of the fifteenth century, these two families were locked in battle for control of the English throne. Kings were murdered and deposed. Armies marched on London. Old noble names were ruined while rising dynasties seized power and lands. The war between the royal houses of Lancaster and York, the most complex in English history, profoundly altered the course of the monarchy. Alison Weir, one of the foremost authorities on British history, brings brilliantly to life both the war itself and the larger-tha-life figures who fought it on the great stage of England. The Wars of the Roses is history at its very best—swift and compelling, rich in character, pageantry, and drama, and vivid in its re-creation of an astonishing period of history.Look for special features inside.Join the Circle for author chats and more.RandomHouseReadersCircle.com

    Carlo Ginzburg uses the trial records of Domenico Scandella, a miller also known as Menocchio, to show how one person responded to the confusing political and religious conditions of his time.For a common miller, Menocchio was surprisingly literate. In his trial testimony he made references to more than a dozen books, including the Bible, Boccaccio's Decameron, Mandeville's Travels, and a "mysterious" book that may have been the Koran. And what he read he recast in terms familiar to him, as in his own version of the creation: "All was chaos, that is earth, air, water, and fire were mixed together; and of that bulk a mass formed—just as cheese is made out of milk—and worms appeared in it, and these were the angels."
