After Sverre's death his only son, Haakon, who was then twenty-eight or thirty years old, was proclaimed king of Norway. In the letter which Sverre wrote to his son on his death-bed, he advised him to make peace with the Church, and Haakon lost no time in calling the archbishop back to the country and in reconciling himself with the bishops. The clergy seemed to be very eager for peace, and each bishop returned to his bishopric, while the archbishop revoked the ban and the interdict without even taking time to obtain the consent of the pope. For this haste in making peace with the king the archbishop was afterward sharply reprimanded by the pope; but in the meanwhile the good relations between king and clergy had strengthened Haakon's position, and the people in general readily acknowledged him. The Bagler party gradually lost most of its support, and after their so-called king, Inge Magnusson, had been killed by one of his own men on an island in Lake Miosen (1202), the party was, for the time being, broken up. Some went to King Haakon and begged for mercy, the remainder fled either to Sweden or Denmark, and there was again peace in the country. The peace, however, did not last very long, this time probably on account of strained relations between the king and his stepmother, the queen-dowager Margreta. During the festivities in Bergen at Christmas, 1203, King Haakon was taken suddenly ill, and on January 1, 1204, he died, with all the symptoms of having been poisoned. It was the general opinion that Queen Margreta was the cause of his death. She was obliged to leave the country, and returned to her old home in Sweden. The death of King Haakon caused great sorrow, for he had been very popular; besides, it was generally supposed that he left no issue.
