She was born in 1193, younger sister of Countess Joanna I of Burgundy. From the time of her father's assassination at Besançon in 1200, she was next-in-line to the county, eventually succeeding Joanna after her death in 1205. Her uncle Philip of Swabia, German king since 1198, had ensured her Burgundian heritage.
