In 700, fighting broke out over the succession of the just disappeared king, Cunipert (to which was faithful), Rotarit stood in favor of his son, Liutpert, who was still underage, and his tutor Ansprand.
Raginpert, supported by the Lombards of Neustria (the Northwest region of the kingdom) ascended to the throne and immediately associated his son, the future Aripert II.
With the death of Raginpert, which occurred a few months after the battle of Novara, Rotarit and Ansprand imprisoned Aripert II and restored Liutpert to the throne.
Aripert II, however, managed to escape and the following year (702) defeated the protectors of Liutpert at Pavia, deposed and imprisoned the young king, and crowned himself in his place.
After forcing Rotarit to shave his beard and his head as a sign of great dishonor, Aripert moved him to Turin where he killed him in 702.
