The first three bishops of Linköping were Herbert, Richard and Gisle (c. 1138–48). Then came Stenar, who apparently resigned in 1160 and subsequently became Bishop of Vexiö. Notable bishops after him were Kol (c. 1160–96), who died on a pilgrimage in Jerusalem, Bengt Magnusson, who was killed at the Battle of Lihula in Estonia on 8 August 1220, and Benedict (1220–37). The last Catholic bishop of Linköping was Hans Brask (born 1464; bishop, 1513–27; died 30 July 1539). He was compelled to leave his diocese in 1527 owing to the adoption of Lutheranism in Sweden at the Diet of Västerås.
Council of Skenninge
Of the numerous provincial and diocesan synods held in the Diocese of Linköping, the Council of Skenninge (1248) was the most important. The papal legate, Cardinal William of Sabina, presided and the celibacy of the clergy was strongly enforced. The following religious institutions were set up in the diocese between the twelfth and the sixteenth centuries: the cathedral chapter, which consisted at the time of the Reformation of a dean, an archdeacon, a subdean, nine canons and fifteen other prebendaries; the Cistercians had three houses for men, the abbeys of Alvastra, the mother-house of the Cistercian Order in Sweden, in Östergötland and Nydala in Småland, both founded in 1143, and Gutvalla (Roma) in Gotland; also four nunneries, Vreta Abbey (1160), Askaby, Byarum, dissolved about 1250 and the nuns transferred to Sko (in Upland) and Solberga Abbey (Gotland); the Brigittines, who had the great Abbey of Vadstena; the Dominicans, who possessed priories at Skenninge (1220?), Visby (1240) and Kalmar, as well as nunneries at Skenninge (1260) and Kalmar (1286). There were hospitals at Linköping, Visby (2), Söderköping (2) Skenninge (2), Kalmar (2), Norrabygd (Uknabäck) and on the Island of Öland. Most of these institutions were suppressed at the Reformation.
