Joan II of Navarre (1312-1349) was the only surviving child of Louis I of Navarre and Margaret of Burgundy.
Joan's paternity was doubtful because her mother was involved in the Tower of Nesle affair scandal, but Louis declared her his legitimate daughter before he died in 1316.
However, due to Salic Law, females were excluded from the line of succession, and Louis's brother was declared king as Philip V.
After Charles IV died in 1328, the Navarrese expelled the French governor and declared Joan the rightful monarch of Navarre. In France, Philip of Valois was crowned king as Philip VI. He concluded an agreement with Joan and her husband, who renounced Joan's claims to Champagne and Brie in exchange for three counties, while Philip acknowledged their right to Navarre.
