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.

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.

William II (1087-1100), or William Rufus, will always be most famous for his death: killed by an arrow while out hunting, perhaps through accident or perhaps murder. But, as John Gillingham makes clear in this elegant book, as the son and successor to William the Conqueror it was William Rufus who had to establish permanent Norman rule. A ruthless, irascible man, he frequently argued acrimoniously with his older brother Robert over their father's inheritance - but he also handed out effective justice, leaving as his legacy one of the most extraordinary of all medieval buildings, Westminster Hall.

King John ruled England for seventeen and a half years, yet his entire reign is usually reduced to one image: of the villainous monarch outmanoeuvred by rebellious barons into agreeing to Magna Carta at Runnymede in 1215. Ever since, John has come to be seen as an archetypal tyrant. But how evil was he? In this perceptive short account, Nicholas Vincent unpicks John's life through his deeds and his personality. The youngest of four brothers, overlooked and given a distinctly unroyal name, John seemed doomed to failure. As king, he was reputedly cruel and treacherous, pursuing his own interests at the expense of his country, losing the continental empire bequeathed to him by his father Henry and his brother Richard and eventually plunging England into civil war. Only his lordship of Ireland showed some success. Yet, as this fascinating biography asks, were his crimes necessarily greater than those of his ancestors - or was he judged more harshly because, ultimately, he failed as a warlord?

Known as 'the anarchy', the reign of Stephen (1135-1141) saw England plunged into a civil war that illuminated the fatal flaw in the powerful Norman monarchy, that without clear rules ordering succession, conflict between members of William the Conqueror's family were inevitable. But there was another problem, too: Stephen himself. With the nobility of England and Normandy anxious about the prospect of a world without the tough love of the old king Henry I, Stephen styled himself a political panacea, promising strength without oppression. As external threats and internal resistance to his rule accumulated, it was a promise he was unable to keep. Unable to transcend his flawed claim to the throne, and to make the transition from nobleman to king, Stephen's actions betrayed uneasiness in his role, his royal voice never quite ringing true. The resulting violence that spread throughout England was not, or not only, the work of bloodthirsty men on the make. As Watkins shows in this resonant new portrait, it arose because great men struggled to navigate a new and turbulent kind of politics that arose when the king was in eclipse.

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.

'After my death,' George V said of his eldest son and heir, 'the boy will ruin himself within twelve months.' The forecast proved uncannily accurate. Edward VIII came to the throne in January 1936, provoked a constitutional crisis by his determination to marry the American divorcée Wallis Simpson, and abdicated in December. He was never crowned king. In choosing the woman he loved over his royal birthright, Edward shook the monarchy to its foundations. Given the new title 'Duke of Windsor' and essentially sent into exile, he remained a visible skeleton in the royal cupboard until his death in 1972 and he haunts the house of Windsor to this day. Drawing on unpublished material, notably correspondence with his most loyal (though much tried) supporter Winston Churchill, Piers Brendon's superb biography traces Edward's tumultuous public and private life from bright young prince to troubled sovereign, from wartime colonial governor to sad but glittering expatriate. With pace and panache, it cuts through the myths that still surround this most controversial of modern British monarchs.
