The elder daughter of Henry VIII, Mary I (1553-58) became England's ruler on the unexpected death of her brother Edward VI. Her short reign is one of the great potential turning points in the country's history. As a convinced Catholic and the wife of Philip II, king of Spain and the most powerful of all European monarchs, Mary could have completely changed her country's orbit, making it a province of the Habsburg Empire and obedient again to Rome. These extraordinary possibilities are fully dramatized in John Edward's superb short biography. The real Mary I has almost disappeared under the great mass of Protestant propaganda that buried her reputation during her younger sister, Elizabeth I's reign. But what if she had succeeded?

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.

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.

'The experience of insecurity, it turned out, would shape one of the most remarkable monarchs in England's history' In the popular imagination, as in her portraits, Elizabeth I is the image of monarchical power. But this image is as much armour as a reflection of the truth. In this illuminating account of England's iconic queen, Helen Castor reveals her reign as shaped by a profound and enduring insecurity that was a matter of both practical politics and personal psychology.

William III (1689-1702) & Mary II (1689-94) (Britain's only ever 'joint monarchs') changed the course of the entire country's history, coming to power through a coup (which involved Mary betraying her own father), reestablishing parliament on a new footing and, through commiting Britain to fighting France, initiating an immensely long period of warfare and colonial expansion. Jonathan Keates' wonderful book makes both monarchs vivid, the cold, shrewd 'Dutch' William and the shortlived Mary, whose life and death inspired Purcell to write some of his greatest music.

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?

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.

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.

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.

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.
