Upon returning to Norway in 1111, Sigurd came back to a flourishing and prosperous kingdom. King Eystein had created a strong and stable country and the church gained more wealth, power and prestige. During Sigurd's reign, the tithe (a 10% tax to support the church) was introduced in Norway, which greatly strengthened the church in the country. Sigurd also founded the diocese of Stavanger. He had been denied divorce by the bishop in Bergen, so he simply installed another bishop further south and had him perform the divorce.
