Conrad's son, Rudolph I of Burgundy, who had inherited the commendatory abbacy from him, succeeded Boson as king and was crowned in 888 in a ceremony at the abbey itself, which he then made the royal residence. The offspring of Conrad of Auxerre became the Kings of Burgundy, in a line running from Rudolf I to Rudolf III.
They directed the abbey until around the year 1000. The monastery remained the property of the Kingdom of Burgundy until 1033, when, through the defeat in battle of Eudes, a nephew of Rudolf III, it passed to the control of the House of Savoy.
