With the archbishop absent, Sverre tightened his grip on the bishops, and on Nikolas Arnesson in particular. Nikolas was the half-brother of Inge Krokrygg and had become bishop of Oslo in 1190 against Sverre's wish. After the destruction of the Øyskjeggs at Florvåg, Sverre arranged a meeting with Nikolas where he claimed to have proof that the bishop had colluded with the Øyskjeggs. The king accused Nikolas of treason and threatened severe punishment. Nikolas submitted, and on 29 June, together with the other bishops, he crowned Sverre as King of Norway. Sverre's domestic priest was elected bishop of Bergen.
