Son of Theobald III of Champagne and Blanche of Navarre, the youngest daughter of Sancho VI of Navarre. His father died before he was born, and Blanche ruled the county as regent until Theobald turned twenty-one in 1222.
He was a notable trouvère, and many of his songs have survived, including some with music.
Also called Theobald I of Navarre, the Troubadour, the Chansonnier, and the Posthumous, was Count of Champagne (as Theobald IV) from birth and King of Navarre from 1234. He was the first Frenchman to rule Navarre.
