In 1796, Louis Philippe supposedly fathered a child with Beata Caisa Wahlborn (1766–1830) named Erik Kolstrøm (1796–1879). In 1808, Louis Philippe proposed to Princess Elizabeth, daughter of King George III of the United Kingdom. His Catholicism and the opposition of her mother Queen Charlotte meant the Princess reluctantly declined the offer. In 1809, Louis Philippe married Princess Maria Amalia of Naples and Sicily, daughter of King Ferdinand IV of Naples and Maria Carolina of Austria. The ceremony was celebrated in Palermo 25 November 1809. The marriage was considered controversial, because she was the niece of Marie Antoinette, while he was the son of Louis Philippe II, Duke of Orléans who was considered to have played a part in the execution of her aunt. Her mother was skeptical to the match for the same reason. She had been very close to her younger sister and devastated by her execution, but she had given her consent after he had convinced her that he was determined to compensate for the mistakes of his father, and after having agreed to answer all her questions regarding his father. After the abdication of Napoleon, Louis Philippe, known as "Louis Philippe, Duke of Orléans", returned to France during the reign of his cousin Louis XVIII, at the time of the Bourbon Restoration. Louis Philippe had reconciled the Orléans family with Louis XVIII in exile, and was once more to be found in the elaborate royal court. However, his resentment at the treatment of his family, the cadet branch of the House of Bourbon under the "Ancien Régime", caused friction between him and Louis XVIII, and he openly sided with the liberal opposition. Louis Philippe was on far friendlier terms with Louis XVIII's brother and successor, Charles X, who acceded to the throne in 1824, and with whom he socialized. However, his opposition to the policies of Villèle and later of Jules de Polignac caused him to be viewed as a constant threat to the stability of Charles' government. This soon proved to be to his advantage. In 1830, the July Revolution overthrew Charles X, who abdicated in favour of his 10-year-old grandson, Henri, Duke of Bordeaux, and, naming Louis Philippe "Lieutenant général du royaume", charged him to announce to the popularly elected Chamber of Deputies his desire to have his grandson succeed him. Louis Philippe did not do this, in order to increase his own chances of succession.
