'To be a medieval king was a job of work ... This was a man who knew how to run a complex organization. He was England's CEO' The youngest of William the Conqueror's sons, Henry I came to unchallenged power only after two of his brothers died in strange hunting accidents and he had imprisoned the other. He was destined to become one of the greatest of all medieval monarchs, both through his own ruthlessness, and through his dynastic legacy. Edmund King's engrossing portrait shows a strikingly charismatic, intelligent and fortunate man, whose rule was looked back on as the real post-conquest founding of England as a new realm: wealthy, stable, bureaucratised and self-confident.

Foremost medieval historian Anne Curry offers a new reinterpretation of Henry V and the battle that defined his kingship: Agincourt Henry V's invasion of France, in August 1415, represented a huge gamble. As heir to the throne, he had been a failure, cast into the political wilderness amid rumours that he planned to depose his father. Despite a complete change of character as king - founding monasteries, persecuting heretics, and enforcing the law to its extremes - little had gone right since. He was insecure in his kingdom, his reputation low. On the eve of his departure for France, he uncovered a plot by some of his closest associates to remove him from power. Agincourt was a battle that Henry should not have won - but he did, and the rest is history. Within five years, he was heir to the throne of France. In this vivid new interpretation, Anne Curry explores how Henry's hyperactive efforts to expunge his past failures, and his experience of crisis - which threatened to ruin everything he had struggled to achieve - defined his kingship, and how his astonishing success at Agincourt transformed his standing in the eyes of his contemporaries, and of all generations to come.

Henry VI, son of the all-conquering Henry V, was one of the least able and least successful of English kings. His long reign, which started when he was only nine months old, ended in catastrophe, with the loss of England's territories in France and a bankrupt England's long decline into civil war: the wars of the Roses. Yet, failure though Henry undoubtedly was, he remains an enigma. Was he always, as he became in the last disastrous years of his rule, a holy fool, simple-minded to the point of insanity and prey to the ambitions of others? Or was he more active and, as some have suggested, actively malign? In this groundbreaking new portrait, James Ross shows a king whose priorities diverged sharply from what England expected of its monarchs, and whose fitful engagement with government was directly, though not solely, responsible for the disasters that engulfed the kingdom during his reign.

Charismatic, insatiable and cruel, Henry VIII was, as John Guy shows, a king who became mesmerized by his own legend - and in the process destroyed and remade England. Said to be a 'pillager of the commonwealth', this most instantly recognizable of kings remains a figure of extreme contradictions: magnificent and vengeful; a devout traditionalist who oversaw a cataclysmic rupture with the church in Rome; a talented, towering figure who nevertheless could not bear to meet people's eyes when he talked to them. In this revealing new account, John Guy looks behind the mask into Henry's mind to explore how he understood the world and his place in it - from his isolated upbringing and the blazing glory of his accession, to his desperate quest for fame and an heir and the terrifying paranoia of his last, agonising, 54-inch-waisted years.

Henry II (1154-89) through a series of astonishing dynastic coups became the ruler of an enormous European empire. One of the most dynamic, restless and clever men ever to rule England, he was brought down both by his catastrophic relationship with his archbishop Thomas Becket and his debilitating arguments with his sons, most importantly the future Richard I and King John. His empire may have ultimately collapsed, but in Richard Barber's vivid and sympathetic account the reader can see why Henry II left such a compelling impression on his contemporaries.

Henry III was a medieval king whose long reign continues to have a profound impact on us today. He was on the throne for 56 years and during this time England was transformed from being the private play-thing of a French speaking dynasty into a medieval state in which the king answered for his actions to an English parliament, which emerged during Henry's lifetime. Despite Henry's central importance for the birth of parliament and the development of a state recognisably modern in many of its institutions, it is Henry's most vociferous opponent, Simon de Montfort, who is in many ways more famous than the monarch himself. Henry is principally known today as the driving force behind the building of Westminster Abbey, but he deserves to be better understood for many reasons - as Stephen Church's sparkling account makes clear.

Edward VI, the only son of Henry VIII, became king at the age of nine and died wholly unexpectedly at the age of fifteen. All around him loomed powerful men who hoped to use the child to further their own ends, but who were also playing a long game - assuming that Edward would long outlive them and become as commanding a figure as his father had been. Stephen Alford's wonderful book gives full play to the murky, sinister nature of Edward's reign, but is also a poignant account of a boy learning to rule, learning to enjoy his growing power and to come out of the shadows of the great aristocrats around him. England's last child monarch, Edward would have led his country in a quite different direction to the catastrophic one caused by his death.

Richard I's reign is both controversial and seemingly contradictory. One of England's most famous medieval monarchs and a potent symbol of national identity, he barely spent six months on English soil during a ten-year reign and spoke French as his first language. Contemporaries dubbed him the 'Lionheart', reflecting a carefully cultivated reputation for bravery, prowess and knightly virtue, but this supposed paragon of chivalry butchered close to 3,000 prisoners in cold blood on a single day. And, though revered as Christian Europe's greatest crusader, his grand campaign to the Holy Land failed to recover the city of Jerusalem from Islam. Seeking to reconcile this conflicting evidence, Thomas Asbridge's incisive reappraisal of Richard I's career questions whether the Lionheart really did neglect his kingdom, considers why he devoted himself to the cause of holy war and asks how the memory of his life came to be interwoven with myth. Richard emerges as a formidable warrior-king, possessed of martial genius and a cultured intellect, yet burdened by the legacy of his dysfunctional dynasty and obsessed with the pursuit of honour and renown.

Edward the Confessor, the last great king of Anglo-Saxon England, canonized nearly 100 years after his death, is in part a figure of myths created in the late middle ages. In this revealing portrait of England's royal saint, David Woodman traces the course of Edward's twenty-four-year-long reign through the lens of contemporary sources, from the Anglo-Saxon Chronicle and the Vita Ædwardi Regis to the Bayeux Tapestry, to separate myth from history and uncover the complex politics of his life. He shows Edward to be a shrewd politician who, having endured a long period of exile from England in his youth, ascended the throne in 1042 and came to control a highly sophisticated and powerful administration. The twists and turns of Edward's reign are generally seen as a prelude to the Norman Conquest in 1066. Woodman explains clearly how events unfolded and personalities interacted but, unlike many, he shows a capable and impressive king at the centre of them.

Overturning the established picture of the dour old lady, this is a fresh and engaging portrait from one of our most talented royal biographers.
