List of heads of government of Norway

This is a list of heads of government of Norway. In the modern era, the head of government has the title prime minister (Norwegian: Statsminister). At various times in the past, the highest governmental title has included steward (Norwegian: Rigsstatholder), viceroy (Norwegian: Vicekonge) and first minister (Norwegian: Førstestatsraad)
Until 1873, the King of the personal union between Sweden and Norway governed Norway through two cabinets: one in Stockholm and another in Christiania (now Oslo). The newly created Stockholm cabinet consisted of a prime minister and two ministers, whose role was to convey the attitudes of the Christiania cabinet to the Swedish King. The cabinet in Christiania was led by a steward (Norwegian: Rigsstatholder). For brief periods, the incumbent crown prince was appointed Viceroy of Norway by the King, in which case the viceroy became the highest authority in Christiania. Whenever the King was present in Christiania, however, he assumed the highest authority, thus putting the governor or viceroy temporarily out of charge. Likewise, when there was no governor, viceroy, or king present in Christiania (which was not unusual), the cabinet was led by the first minister, who was the most prominent member of the cabinet.
In July 1873, the position of governor was abolished after being vacant since 1856. Simultaneously, the post of First Minister in Christiania was upgraded to Prime Minister of Norway. Although the office of Norwegian prime minister in Stockholm still existed, the real power and influence over state affairs was moved to the prime minister in Christiania, while prime minister in Stockholm became the second highest cabinet position, responsible for conveying the government's views to the King. When the union was dissolved in 1905, the position of prime minister in Stockholm was abolished.
The Steward of Norway, styled Rigsstatholder in Danish (riksstattholder in modern Norwegian spelling), meaning Royal steward of the realm (see Steward), was the appointed head of the Norwegian Government in the absence of the Monarch during the Dano-Norwegian union. As Norway was a separate kingdom, with its own laws and institutions, the position of Steward of Norway was arguably the most influential position for a Danish-Norwegian nobleman or royal to hold, second to the King.
