'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.

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.

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.

Part of the Penguin Monarchs series: short, fresh, expert accounts of England's rulers in a collectible format Queen Victoria inherited the throne at 18 and went on to become the longest-reigning female monarch in history, in a time of intense industrial, cultural, political, scientific and military change within the United Kingdom and great imperial expansion outside of it (she was made Empress of India in 1876). Overturning the established picture of the dour old lady, this is a fresh and engaging portrait from one of our most talented royal biographers. Jane Ridley is Professor of Modern History at Buckingham University, where she teaches a course on biography. Her previous books include The Young Disraeli; a study of Edwin Lutyens, The Architect and his Wife, which won the 2003 Duff Cooper Prize; and the best-selling Bertie: A Life of Edward VII. A Fellow of the Royal Society for Literature, Ridley writes for the Spectator and other newspapers, and has appeared on radio and several television documentaries. She lives in London and Scotland.

No English king has so divided opinion, both during his reign and in the centuries since, more than Richard III. He was loathed in his own time for the never-confirmed murder of his young nephews, the Princes in the Tower, and died fighting his own subjects on the battlefield. This is the vision of Richard we have inherited from Shakespeare. Equally, he inspired great loyalty in his followers. In this enlightening, even-handed study, Rosemary Horrox builds a complex picture of a king who by any standard failed as a monarch. He was killed after only two years on the throne, without an heir, and brought such a decisive end to the House of York that Henry Tudor was able to seize the throne, despite his extremely tenuous claim. Whether Richard was undone by his own fierce ambitions, or by the legacy of a Yorkist dynasty which was already profoundly dysfunctional, the end result was the same: Richard III destroyed the very dynasty that he had spent his life so passionately defending.

On Christmas Day 1066, William, duke of Normandy was crowned in Westminster, the first Norman king of England. It was a disaster: soldiers outside, thinking shouts of acclamation were treachery, torched the surrounding buildings. To later chroniclers, it was an omen of the catastrophes to come. During the reign of William the Conqueror, England experienced greater and more seismic change than at any point before or since. Marc Morris's concise and gripping biography sifts through the sources of the time to give a fresh view of the man who changed England more than any other, as old ruling elites were swept away, enemies at home and abroad (including those in his closest family) were crushed, swathes of the country were devastated and the map of the nation itself was redrawn, giving greater power than ever to the king. When, towards the end of his reign, William undertook a great survey of his new lands, his subjects compared it to the last judgement of God, the Domesday Book. England had been transformed forever.

This first comprehensive biography of Henry I, the youngest son of William the Conqueror and an elusive figure for historians, offers a rich and compelling account of his tumultuous life and reign. Judith Green argues that although Henry's primary concern was defence of his inheritance this did not preclude expansion where circumstances were propitious, notably into Welsh territory. His skilful dealings with the Scots permitted consolidation of Norman rule in the northern counties of England, while in Normandy every sinew was strained to defend frontiers through political alliances and stone castles. Green argues that although Henry's own outlook was essentially traditional, the legacy of this fascinating and ruthless personality included some fundamentally important developments in governance. She also sheds light on Henry's court, suggesting that it made an important contribution to the flowering of court culture throughout twelfth-century Europe.
