Coronations in Norway were held from 1164 to 1906, mostly in the Nidaros Cathedral in Trondheim. Although a crowning ceremony was formerly mandated by the nation's constitution, this requirement was eliminated in 1908. However, Norwegian kings have since chosen voluntarily to take part in a ritual of "benediction" to mark their accession to the throne, during which the crown is present, but not physically bestowed upon the sovereign. The new ceremony retains some of the religious elements of earlier rites, while eliminating other features now considered to be "undemocratic".
The first coronation in Norway—and in all of Scandinavia—took place in Bergen in 1163 or 1164. These rites continued in the Old Cathedral there until the capital was moved to Oslo under Haakon V of Norway. While some crownings were held in Oslo thereafter, most took place at Nidaros Cathedral, in Trondheim. Norwegian kings had historically been proclaimed (konungstekja in Old Norse) at the Øyrating in Trondheim, starting with Harald Fairhair or Haakon the Good in the 10th century; this continued even after the tradition of coronations began. Sometimes this led to competing claims: King Sverre, for example, was hailed as king at Øyrating in 1177, but not crowned until well after the death of King Magnus V in 1184. Ultimately, the coronation rite replaced the konungstekja ceremonies altogether until the resurrection of the latter in the modern benediction service.
In the late 14th century, Norway, Sweden and Denmark were united in the Kalmar Union. During this era, monarchs were crowned in all three countries consecutively. After the federation was dissolved, Norway remained unified with Denmark under the Danish king until 1814. After the introduction of autocracy in Denmark in 1660, no further coronations took place in Norway until after the advent of the Constitution of Norway in 1814 and the Swedish Union, which took place during that same year. Throughout the Danish Union, the king of Denmark-Norway only went through one ceremony, in Denmark, in which he placed the crown upon his own head and was anointed.
