While siblings can provide companionship and protection, rivalries among siblings are bound to occur. Sibling Rivalry: Clashes Between English Royals Throughout History explores sibling rivalries at a much grander scale, demonstrating how feuds can impact the fate of an entire country. This book analyses England’s fiery past and development through viewing the feuds of several English royal families in chronological order. These royal siblings include King Henry I and Robert Curthouse (the House of Normandy), Richard the Lionheart and Prince John (House of Anjou), Queen Mary I and Queen Elizabeth I (House of Tudor), and others. Through viewing these different conflicts in history, Ruggiero offers a new perspective on the history of England and the impact these rivalries have had on the Royal family and the nation.
