'James was a king tragically trapped by principle. Yet was it wise to attempt to change the national religion?' The short reign of James II is generally seen as one of the most catastrophic in British history, ending in his exile after he unsuccessfully tried to convert England to Catholicism, a crisis that would haunt the monarchy for generations. Ultimately, David Womersley's biography shows, James was a man whose blindness to subtlety and political reality brought about his ruinous downfall.

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.

In September 2015 Queen Elizabeth II becomes Britain's longest-reigning monarch. During her long lifetime Britain and the world have changed beyond recognition, yet throughout she has stood steadfast as a lasting emblem of stability, continuity and public service. Historian and senior politician Douglas Hurd has seen the Queen at close quarters, as Home Secretary and then on overseas expeditions as Foreign Secretary. Here he considers the life and role of Britain's most greatly admired monarch, who, inheriting a deep sense of duty from her father George VI, has weathered national and family crises, seen the end of an Empire and heard voices raised in favour of the break-up of the United Kingdom. Hurd creates an arresting portrait of a woman deeply conservative by nature yet possessing a ready acceptance of modern life and the awareness that, for things to stay the same, they must change. With a preface by HRH Prince William, Duke of Cambridge

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.

Richard II (1377-99) came to the throne as a child, following the long, domineering, martial reign of his grandfather Edward III. He suffered from the disastrous combination of a most exalted sense of his own power and an inability to impress that power on those closest to the throne. Neither trusted nor feared, Richard battled with a whole series of failures and emergencies before finally succumbing to a coup, imprisonment and murder. Laura Ashe's brilliant account of his reign emphasizes the strange gap between Richard's personal incapacity and the amazing cultural legacy of his reign - from the Wilton Diptych to Sir Gawain and the Green Knight, Piers Plowman and The Canterbury Tales.

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.

'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.
