The House of Brittany was a noble family that played a significant role in the history of Brittany, a region in north-western France. It emerged in the 9th century and became influential through its dukes, who ruled Brittany and sought to maintain its independence from the French crown. The house is known for its unique culture and strong ties to both the French and English crowns. Throughout its history, the House of Brittany produced several notable figures, including Duke John IV and Duchess Anne of Brittany. The house's legacy includes the eventual union of Brittany with France in the 16th century, which marked the end of its ducal independence.
