Louis Philippe I (6 October 1773 – 26 August 1850) was King of the French from 1830 to 1848. Like his father, Louis Philippe II, Duke of Orléans, he initially supported the French Revolution. However following the deposition and execution of his cousin, King Louis XVI, Louis Philippe fled the country. His father, despite having denounced his son's actions and voted for the death of the King, was imprisoned and executed that same year. Louis Philippe spent the next 21 years in exile before returning during the Bourbon Restoration. He was proclaimed king in 1830 after his cousin Charles X was forced to abdicate by the July Revolution. The reign of Louis Philippe, known as the July Monarchy, was dominated by wealthy industrialists and bankers. He followed conservative policies, especially under the influence of the French statesman François Guizot during the period 1840–48. He also promoted friendship with Britain and sponsored colonial expansion, notably the French conquest of Algeria. His popularity faded as economic conditions in France deteriorated in 1847, and he was forced to abdicate after the outbreak of the French Revolution of 1848. He lived out his life in exile in the United Kingdom. His supporters were known as Orléanists, as opposed to Legitimists who supported the main line of the House of Bourbon.
