'He seems to have laboured under an almost child-like misapprehension about the size of his world. Had greatness not been thrust upon him, he might have lived a life of great harmlessness.' The reign of Edward II was a succession of disasters. Unkingly, inept in war, and in thrall to favourites, he preferred digging ditches and rowing boats to the tedium of government. His infatuation with a young Gascon nobleman, Piers Gaveston, alienated even the most natural supporters of the crown. Hoping to lay the ghost of his soldierly father, Edward I, he invaded Scotland and suffered catastrophic defeat at the Battle of Bannockburn. After twenty ruinous years, betrayed and abandoned by most of his nobles and by his wife and her lover, Edward was imprisoned in Berkeley Castle and murdered - the first English king since the Norman Conquest to be deposed.

'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 Drawing on unpublished material, notably correspondence with his most loyal (though much tried) supporter Winston Churchill, Piers Brendon's superb biography traces Edward's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.

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.

For a man with such conventional tastes and views, George V had a revolutionary impact. Almost despite himself he marked a decisive break with his flamboyant predecessor Edward VII, inventing the modern monarchy, with its emphasis on frequent public appearances, family values and duty. George V was an effective war-leader and inventor of 'the House of Windsor'. In an era of ever greater media coverage--frequently filmed and initiating the British Empire Christmas broadcast--George became for 25 years a universally recognised figure. He was also the only British monarch to take his role as Emperor of India seriously. While his great rivals (Tsar Nicolas and Kaiser Wilhelm) ended their reigns in catastrophe, he plodded on. David Cannadine's sparkling account of his reign could not be more enjoyable, a masterclass in how to write about Monarchy, that central--if peculiar--pillar of British life.

A major new title in the Penguin Monarchs series In his fascinating new book in the Penguin Monarchs series, Richard Abels examines the long and troubled reign of Aethelred II the 'Unraed', the 'Ill-Advised'. It is characteristic of Aethelred's reign that its greatest surviving work of literature, the poem The Battle of Maldon, should be a record of heroic defeat. Perhaps no ruler could have stemmed the encroachment of wave upon wave of Viking raiders, but Aethelred will always be associated with that failure. Richard Abels is Professor Emeritus at the United States Naval Academy. He is the author of Alfred the Great: War, Kingship and Culture in Anglo-Saxon England and Lordship and Military Obligation in Anglo-Saxon England. He is a Fellow of the Royal Historical Society.

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?
