Chlothar II
Also in 587, Gontrand compelled obedience from Waroch II, the Breton ruler of the Vannetais. He forced the renewal of the oath of 578 in writing and demanded 1,000 "solidi" in compensation for raiding the Nantais. In 588, the compensation was not yet paid, as Waroch promised it to both Gontrand and Chlothar II, who probably had suzerainty over Vannes.
