Clash of Crowns: William the Conqueror, Richard Lionheart, and Eleanor of Aquitaine--A Story of Bloodshed, Betrayal, and RevengeHardcover, 16 March 2012

Conflict between England and France was a fact of life for centuries, but few realize that this conflict originated with the Vikings and their settlement of what would become Normandy. In this compelling and entertaining history, Mary McAuliffe takes the reader back to those dark and turbulent times when Viking descendant William the Conqueror became king of England, yet as duke of Normandy remained an unwilling subject to the French crown. This led to ongoing hostility between his descendants and generations of French monarchs, culminating in the clash between young Philip Augustus of France and his royal English rivals, most notably Richard Lionheart. Mary McAuliffe colorfully provides the background and context for this "clash of crowns," whose outcome would shape the course of English and French history throughout the centuries that followed.
