The tragedy of Charles I dominates one of the most strange and painful periods in British history as the whole island tore itself apart over a deadly, entangled series of religious and political disputes. In Mark Kishlansky's brilliant account it is never in doubt that Charles created his own catastrophe, but he was nonetheless opposed by men with far fewer scruples and less consistency who for often quite contradictory reasons conspired to destroy him. This is a remarkable portrait of one of the most talented, thoughtful, loyal, moral, artistically alert and yet, somehow, disastrous of all this country's rulers.

Although he styled himself 'His Highness', adopted the court ritual of his royal predecessors, and lived in the former royal palaces of Whitehall and Hampton Court, Oliver Cromwell was not a king - in spite of the best efforts of his supporters to crown him. Yet, as David Horspool shows in this illuminating new portrait of England's Lord Protector, Cromwell, the Puritan son of Cambridgeshire gentry, wielded such influence that it would be a pretence to say that power really lay with the collective. The years of Cromwell's rise to power, shaped by a decade-long civil war, saw a sustained attempt at the collective government of England; the first attempts at a real Union of Britain; the beginnings of empire; a radically new solution to the idea of a national religion; atrocities in Ireland; and the readmission to England of the Jews, a people officially banned for over three and a half centuries. At the end of it, Oliver Cromwell had emerged as the country's sole ruler: to his enemies, and probably to most of his countrymen, his legacy looked as likely to last as that of the Stuart dynasty he had replaced.

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?

Charles II has always been one of the most instantly recognisable British kings - both in his physical appearance, disseminated through endless portraits, prints and pub signs, and in his complicated mix of lasciviousness, cynicism and luxury. His father's execution and his own many years of exile made him a guarded, curious, unusually self-conscious ruler. He lived through some of the most striking events in the national history - from the Civil Wars to the Great Plague, from the Fire of London to the wars with the Dutch. Clare Jackson's marvellous book takes full advantage of its irrepressible subject.

The formation of England occurred against the odds: an island divided into rival kingdoms, under savage assault from Viking hordes. But, after King Alfred ensured the survival of Wessex and his son Edward expanded it, his grandson Athelstan inherited the rule of both Mercia and Wessex, conquered Northumbria and was hailed as Rex totius Britanniae: 'King of the whole of Britain'. Tom Holland recounts this extraordinary story with relish and drama, transporting us back to a time of omens, raven harbingers and blood-red battlefields. As well as giving form to the figure of Athelstan - devout, shrewd, all too aware of the precarious nature of his power, especially in the north - he introduces the great figures of the age, including Alfred and his daughter Aethelflaed, 'Lady of the Mercians', who brought Athelstan up at the Mercian court. Making sense of the family rivalries and fractious conflicts of the Anglo-Saxon rulers, Holland shows us how a royal dynasty rescued their kingdom from near-oblivion and fashioned a nation that endures to this day.

Charles II is restored to the English throne, and his court is lively and even scandalous. The country is eager for succession to be clear and certain: The next king will be the son of Charles II and his queen, Catherine of Braganza. Yet Catherine, daughter of the king of Portugal and a Catholic, has never been popular with the English people. She is also having great difficulty conceiving an heir, even as many of Charles’s well-known mistresses are bearing his children with ease. Catherine is aware that courtiers close to Charles are asking him to divorce her and take another wife—yet she is determined to hold her title in the face of all odds. The ninth novel in the beloved Queens of England series, The Merry Monarch’s Wife brings Catherine of Braganza to life and plunges readers into the tumultuous world of Restoration England.

James's reign marked one of the very rare major breaks in England's monarchy. Already James VI of Scotland and a highly experienced ruler who had established his authority over the Scottish Kirk, he marched south on Elizabeth I's death to become James I of England and Ireland, uniting the British Isles for the first time and founding the Stuart dynasty which would, with several lurches, reign for over a century. Indeed his descendant still occupies the throne. A complex, curious man and great survivor, James drastically changed court life in London and presided over such major projects as the Authorized Version of the Bible and the establishment of English settlements in Virginia, Massachusetts, Gujarat and the Caribbean. Although he failed to unite England and Scotland, he insisted that ambassadors acknowledge him as King of Great Britain and that vessels from both countries display a version of the current Union Flag. He was often accused of being too informal and insufficiently regal - but when his son, Charles I, decided to redress these criticisms in his own reign he was destroyed. How much of the roots of this disaster were to be found in James's reign is one of the many problems dramatized in Thomas Cogswell's brilliant and highly entertaining new book.

Part of the Penguin Monarchs series: short, fresh, expert accounts of England's rulers in a collectible format Henry VII was one of England's unlikeliest monarchs. An exile and outsider with barely a claim to the throne, his victory over Richard III at Bosworth Field seemed to many in 1485 only the latest in the sequence of violent convulsions among England's nobility that would come to be known as the Wars of the Roses - with little to suggest that the obscure Henry would last any longer than his predecessor. To break the cycle of division, usurpation, deposition and murder, he had both to maintain a grip on power and to convince England that his rule was both rightful and effective. Here, Sean Cunningham explores how, in his ruthless and controlling kingship, Henry VII did so, in the process founding the Tudor dynasty.

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.

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?
