The war between the fertile Stewarts and the barren Tudors was crucial to the history of the British Isles in the sixteenth century. The legendary struggle, most famously embodied by the relationship between Elizabeth I and her cousin, Mary Queen of Scots, was fuelled by three generations of powerful Tudor and Stewart monarchs. It was the marriage of Margaret Tudor, elder sister of Henry VIII, to James IV of Scotland in 1503 that gave the Tudors a claim to the English throne—a claim which became the acknowledged ambition of Mary Queen of Scots and a major factor in her downfall.

Here is the story of divided families, of flamboyant kings and queens, cultured courts and tribal hatreds, blood feuds, rape and sexual license, of battles and violent deaths. It brings alive a neglected aspect of British history—the blood-spattered steps of two small countries on the northern fringes of Europe towards the union of their crowns. Beginning with the dramatic victories of two usurpers, Henry VII in England and James IV in Scotland, in the late fifteenth century, Linda Porter's Tudors Versus Stewarts sheds new light on Henry VIII, his daughter Elizabeth I and on his great-niece, Mary Queen of Scots, still seductive more than 400 years after her death.
