Philippa of Champagne Royalty
Philippa of Champagne, Lady of Ramerupt and of Venizy (c. 1197 – 20 December 1250) was the third daughter of Queen Isabella I of Jerusalem and Henry II, Count of Champagne. She was the wife of Erard de Brienne-Ramerupt who encouraged her in 1216 to claim the county of Champagne which belonged to her cousin Theobald IV, who was still a minor. This provoked the conflict with Theobald's mother, the Regent, Blanche of Navarre, which erupted into open warfare, and came to be known as the Champagne War of Succession. Blanche's son Theobald, who had the support of King Philip II of France, Frederick II, Holy Roman Emperor, and Eudes III of Burgundy, eventually emerged the victor. Philippa renounced her claim in April 1222, but Theobald was constrained to pay Erard and Philippa a large monetary settlement for his rights to the county. Together, Erard and Philippa had seven daughters and two sons.
