to the former political union consisting of the kingdoms of Denmark and Norway, including the Norwegian dependencies of Iceland, Greenland and the Faroe Islands. The corresponding adjective and demonym is Dano-Norwegian. During Danish rule, Norway kept its separate laws, coinage and army as well as some institutions such as a royal chancellor. Norway's old royal line had died out with the death of Olav IV in 1387, but Norway's remaining a hereditary kingdom became an important factor for the Oldenburg dynasty of Denmark–Norway in its struggles to win elections as kings of Denmark. The Treaty of Kiel (14 January 1814) formally dissolved the Dano-Norwegian union and ceded the territory of Norway proper to the King of Sweden, but Denmark retained Norway's overseas possessions. However, widespread Norwegian resistance to the prospect of a union with Sweden induced the governor of Norway, crown prince Christian Frederick (later Christian VIII of Denmark), to call a constituent assembly at Eidsvoll in April 1814. The assembly drew up a liberal constitution and elected Christian Frederick to the throne of Norway. Following a Swedish invasion during the summer, the peace conditions of the Convention of Moss (14 August 1814) specified that king Christian Frederik had to resign, but Norway would keep its independence and its constitution within a personal union with Sweden. Christian Frederik formally abdicated on 10 August 1814 and returned to Denmark. The Norwegian parliament Storting elected king Charles XIII of Sweden as king of Norway on 4 November. The Storting dissolved the union between Sweden and Norway in 1905, after which the Norwegians elected Prince Charles of Denmark as king of Norway: he reigned as Haakon VII.
