## Body

### Early Life and Succession
Joan I was born on January 14, 1273, to Henry I of Navarre and Blanche of Artois. Upon her father’s death in 1274, she inherited Navarre and Champagne-Brie, becoming queen regnant at age one. Her mother acted as regent until Joan’s marriage to Philip IV of France in 1284, which transferred effective control of her territories to the French crown.

### Reign and Marriage
Joan’s marriage to Philip IV (1284) united Navarre and France under a single monarch, though both kingdoms maintained distinct legal and administrative systems. As queen consort, she supported Philip’s centralization policies, leveraging her inheritance to strengthen French power. Her coat of arms (Arms of Jeanne de Champagne.svg) symbolized this union, combining Navarrese and French heraldry.

### Administrative and Dynastic Impact
Joan governed Champagne and Brie directly, overseeing trade hubs like Troyes. Her territories enriched the French monarchy, funding military campaigns and reinforcing Capetian authority. She bore Philip IV seven children, including three future kings of France (Louis X, Philip V, Charles IV) and Isabella of France, whose marriage to Edward II of England later fueled Anglo-French tensions.

### Death and Legacy
Joan died on April 2, 1305, at the age of 32. Her death led to succession disputes, as her sons’ claims to Navarre and France were challenged by nobles. The union between Navarre and France dissolved in 1328, but her legacy endured through the Capetian dynasty’s expansionist policies and the integration of Champagne into the French realm. Her rule exemplified medieval queens’ dual roles as sovereigns and diplomatic pawns, shaping the fate of two kingdoms through inheritance and marriage.
