Cine s-a căsătorit cu Philippa of Champagne?

Philippa of Champagne (French: Philippe de Champagne) (c. 1197 – 20 December 1250) was the third daughter of Queen Isabella I of Jerusalem and Count Henry II 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.

Érard de Brienne (c. 1170 † 1246) was a French nobleman. He was lord of Ramerupt and of Venizy, and also a pretender to the county of Champagne as an instigator of the Champagne War of Succession. He was a son of André of Brienne and of Alix of Vénizy.
