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.
