The Kennedys and the Windsors: The Story of Two Dynasties, One Born, One Made (Pre-order June 2, 2026)

The Kennedys and the Windsors:  The Story of Two Dynasties, One Born, One Made by Caroline Hallemann Pre-Order June 2nd 2026

A sweeping, revelatory dual biography, The Kennedys and the Windsors by acclaimed journalist Caroline Hallemann tells the extraordinary story of two families who shaped the twentieth century — one born to rule, the other determined to claim its place in history.

For nearly a century, the British royal family and America’s most famous political dynasty have fascinated the world with their glamour, ambition, tragedy, and scandal. Yet until now, their intertwined histories have never been fully told.

Drawing on rich archival research and exclusive interviews, Hallemann traces how an upstart Irish Catholic family rose from outsider status in New England society to dine with kings, captivate queens, and ultimately reach the White House. Along the way, she reveals striking parallels between the two dynasties: Princess Diana and Carolyn Bessette-Kennedy as enduring style icons; Princess Margaret and Lee Radziwill as restless “second sisters”; the troubled next generation of Robert F. Kennedy Jr. and Prince Andrew; and the modern heirs struggling to define power, legacy, and relevance in the twenty-first century.

From Queen Elizabeth II’s coronation to JFK’s historic London visit, from JFK Jr.’s tragic death to Prince Harry’s break from the monarchy, The Kennedys and the Windsors follows the pivotal moments where these families’ paths crossed — and shows how their rival myths of royalty and democracy shaped not only their reputations, but history itself.

Elegant, insightful, and endlessly fascinating, this is a definitive portrait of fame, power, and legacy on both sides of the Atlantic.
