The House of Bernadotte (UK: /ˌbɜːrnəˈdɒt/ BUR-nə-DOT, US: /-ˈdɔːt, ˈbɜːrnədɒt/ -DAWT, BUR-nə-dot) is the royal house of Sweden, which has reigned since 1818. Between 1818 and 1905, it was also the royal house of Norway. Its founder Charles XIV John of Sweden, born a Frenchman as Jean Bernadotte, was adopted by the elderly King Charles XIII of Sweden, who had no other heir and whose Holstein-Gottorp branch of the House of Oldenburg thus was soon to be extinct.
