Theodore was the bishop of Marseille from at least 566 until 591/594. In the 580s, Theodore was at the centre of a dispute over the city of Marseille between King Guntram and his nephew, King Childebert II. He was arrested several times. His troubles are recorded by the contemporary historian Gregory of Tours, who depicts him as a saintly albeit powerless figure who was supported by the laity, but opposed by his own clergy.
