Oscar I (born Joseph François Oscar Bernadotte; 4 July 1799 – 8 July 1859) was King of Sweden and Norway from 8 March 1844 until his death. He was the second monarch of the House of Bernadotte. The only child of King Charles XIV John, Oscar inherited the thrones upon the death of his father. Throughout his reign he would pursue a liberal course in politics in contrast to Charles XIV John, instituting reforms and improving ties between Sweden and Norway. In an address to him in 1857, the Riksdag declared that he had promoted the material prosperity of the kingdom more than any of his predecessors. Early life and family Oscar was born at 291 Rue Cisalpine in Paris (today: 32 Rue Monceau) to Jean-Baptiste Jules Bernadotte, then-French Minister of War and later Marshal of the Empire and Sovereign Prince of Pontecorvo, and Désirée Clary, Napoleon Bonaparte's former fiancée. He was named Joseph after his godfather Joseph Bonaparte, who was married to his mother's elder sister Julie, but was also given the names François Oscar. The latter name was chosen by Napoleon after one of the heroes in the Ossian cycle of poems, and was the name that came to be used in the family, mainly by the mother and the aunt. Désirée is said to have chosen Napoleon to be Oscar's godfather. He spent his first years in France, living with his mother and aunt, partly in Paris, partly at Joseph Bonaparte's country residence, the Château de Mortefontaine north of Paris. In 1807, he received his first tutor, Le Moine. Prince of Sweden As the Swedish king Charles XIII was without legitimate heirs, and Sweden therefore was without an heir to the throne, Oscar's father was proposed as a possible candidate to the Swedish throne in 1810. As one of the arguments for his election, it was argued that he already had a son and the future succession to the throne was secured. A portrait of the young Oscar was handed out at the Riksdag, the Diet of the Four Estates assembled in Örebro to elect an heir to the throne, serving as a lever for the election of Bernadotte. On 21 August 1810, the Riksdag elected Oscar's father as heir-presumptive to the Swedish throne. Two months later, on 5 November, he was formally adopted by the king under the name of "Charles John"; Oscar was then created
