Charles XV succeeds Oscar I in Sweden–Norway

Background. Oscar I, born Joseph François Oscar Bernadotte, was King of Sweden and Norway from 8 March 1844 until his death in 1859. His health deteriorated rapidly in the 1850s, leading to paralysis in 1857. He died on 8 July 1859, four days after his 60th birthday, at the Royal Palace in Stockholm. The succession occurred within the framework of the personal union established in 1814.

Succession. Charles XV, born Carl Ludvig Eugen, was the son of Oscar I. He served as Regent from 25 September 1857, following his father's paralysis. Upon Oscar I's death on 8 July 1859, Charles became King of Sweden as Charles XV and King of Norway as Charles IV. The transition maintained the personal union, with the kings residing in Stockholm where diplomatic representations were located.

Union Context. The personal union between Sweden and Norway lasted from 1814 until 1905. The two states maintained separate constitutions, laws, and administrations, but shared a common monarch and foreign policy. The kings mostly resided in Stockholm. Charles XV's accession continued this arrangement, which had been established through the Convention of Moss and the election of Charles XIII as King of Norway in 1814.
