In Norway, the kings who introduced Christianity which first became known to the people during their martial expeditions. The work of Christianization begun by
Haakon the Good (d. 961 in the
Battle of Fitjar) was carried on by
Olaf Tryggvason (d. 1000 in the
Battle of Svolder) and
Olaf Haraldsson (St. Olaf, d. 1030 in the
Battle of Stiklestad). Both were converted Vikings, the former having been baptized at
Andover, England, by
Aelfeah,
Bishop of Winchester, and the latter at
Rouen by Archbishop Robert. In 997, Olaf Tryggvason founded at the mouth of the river
Nidelva the city of Nidaros (now Trondheim) where he built a
Kongsgård estate and a church; he laboured to spread Christianity in Norway, the
Orkney and
Shetland Islands, the
Faroe Islands,
Iceland, and
Greenland. King Olaf Haraldsson created an episcopal see at Nidaros, installing the monk
Grimkill as bishop. Moreover, many English and German bishops and priests came to Norway. The Norwegian bishops were at first dependent on the
Archbishop of Hamburg-Bremen, and afterwards on the
Archbishop of Lund, Primate of Scandinavia. As the Norwegians wanted an archbishop of their own,
Pope Eugene III, resolving to create a metropolitan see at Nidaros, sent thither as legate (1151) Cardinal
Nicholas of Albano (Nicholas Breakspeare), afterwards Adrian IV. The legate installed Jon Birgerson, previously
Bishop of Stavanger, as Archbishop of Nidaros. The bishops of
Bergen (bishop about 1068),
Faroe Diocese (1047),
Garðar, Greenland (1126),
Hamar (1151),
Hólar, Iceland (1105),
Orkney (1070; suffragan till 1472),
Oslo (1073),
Skálholt, Iceland (1056), and
Stavanger (1130) became suffragans. , the second Archbishop of Nidaros holding a model of the
Nidaros Cathedral Archbishop Birgerson was succeeded by
Eysteinn Erlendsson (Beatus Augustinus, 1158–88), previously royal secretary and treasurer, a man of intellect, strong will, and piety. King
Sverre wished to make the Church a tool of the temporal power, and the archbishop was compelled to flee from Norway to England. He was able to return, and a reconciliation took place later between him and the king, but on Eystein's death King Sverre renewed his attacks, and Archbishop Eric had to leave the country and take refuge with
Absalon, Archbishop of Lund. At last, when King Sverre attacked the papal legate,
Pope Innocent III laid the king and his partisans under interdict. King
Haakon III (1202), son and successor of King Sverre, hastened to make peace with the Church. Pope Innocent III gave Thorer, Archbishop of Drontheim, authority over all Scandinavian territory, including Greenland and Vinland, the Norse name for North America. To regulate ecclesiastical affairs, which had suffered during the struggles with Sverre,
Pope Innocent IV in 1247 sent Cardinal
William of Sabina as legate to Norway. He intervened against encroachments on the part of the bishops, reformed various abuses, and abolished the
ordeal by hot iron. Owing in great measure to the papal legates, Norway became more closely linked with the supreme head of Christendom at Rome. Secular priests,
Benedictines,
Cistercians,
Augustinians,
Dominicans and
Franciscans worked together for the prosperity of the Church. Archbishops Eilif Kortin (d. 1332), Paul Baardson (d. 1346), and Arne Vade (d. 1349) were zealous churchmen. Provincial councils were held, at which serious efforts were made to eliminate abuses and to encourage Christian education and morality. In 1277, the Tønsberg Concord (
Sættargjerden in Tønsberg) was signed between King
Magnus VI of Norway and
Jon Raude, the Archbishop of Nidaros confirming certain privileges of the clergy, the freedom of episcopal elections and similar matters. Nidaros (Trondheim), the metropolis of the ecclesiastical province, was also the capital of Norway. The residence of the kings until 1217, it remained until the
Reformation the heart and centre of the spiritual life of the country. There was situated the tomb of St. Olaf, and around the patron of Norway, "Rex perpetuus Norvegiae", the national and ecclesiastical life of the country was centred. The feast of St. Olaf on 29 July was a day or reunion for "all the nations of the Northern seas, Norwegians, Swedes, Goths,
Cimbrians, Danes and Slavs", to quote an old chronicler, in the cathedral of Nidaros, where the
reliquary of St. Olaf rested near the altar. Built in Roman style by King
Olaf Kyrre (d. 1093), the cathedral had been enlarged by Archbishop Eystein in
Gothic style. It was finished only in 1248 by Archbishop Sigurd Sim. Although several times destroyed by fire, the ancient cathedral was restored each time until the
Reformation in Norway. Then Archbishop Eric Walkendorf was exiled (1521), and his successor,
Olaf Engelbertsen, who had been the instrument of the royal will in the introduction of
Lutheranism, had also, as a partisan of
Christian II, to fly from
Christian III (1537). The reliquaries of St. Olaf and St. Augustine (Eystein) were taken away, sent to
Copenhagen and melted. The bones of St. Olaf were buried in the cathedral, and the place forgotten. == Ecclesiastical province of Nidaros ==
