Joan II was Queen of Navarre from 1328 until her death. She was the only surviving child of Louis X of France, King of France and Navarre, and Margaret of Burgundy. Joan's paternity was dubious because her mother was involved in a scandal, but Louis X declared her his legitimate daughter before he died in 1316. However, the French lords were opposed to the idea of a female monarch and elected Louis X's brother, Philip V, king. The Navarrese noblemen also paid homage to Philip. Joan's maternal grandmother, Agnes of France, and uncle, Odo IV of Burgundy, made attempts to secure the counties of Champagne and Brie to Joan, but the French royal troops defeated her supporters. After Philip V married his daughter to Odo and granted him two counties as her dowry, Odo renounced Joan's claim to Champagne and Brie in exchange for a compensation in March 1318. Joan married Philip of Évreux, who was also a member of the French royal family.

Philippa of Champagne 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.
The Treaty of Orléans was a marriage treaty signed in 1275, that led to a short-lived personal union between the kingdoms of Navarre and France. It was signed by Philip III of France and his cousin Blanche of Artois, mother and regent to the two-year-old Joan I of Navarre. The original intent of the treaty was to not create a personal union, however, but to enable Philip to administer Navarre in Joan's name. Joan was also to marry either Philip's firstborn and heir apparent, Louis, or his second son, Philip. Pope Gregory X explicitly stated that he preferred a match with the younger son, as he probably wished to avoid merging Navarre with France. Louis died in 1276, however, leaving Philip as the only choice per the terms of the treaty.
