In France in 1852, voters were asked whether they approved of the re-establishment of the Empire in the person of Louis Napoléon Bonaparte,  the only president of what republic?
Napoleon III Louis-Napoléon Bonaparte (born Charles-Louis Napoléon Bonaparte; 20 April 1808 – 9 January 1873) was the President of France from 1848 to 1852 and, as Napoleon III, the Emperor of the French from 1852 to 1870. He was the only president of the French Second Republic and the head of the Second French Empire.
Orléanist The Orléanists were a French right-wing (except for 1814–1830) faction which arose out of the French Revolution, as opposed to Legitimists. It governed France 1830–1848 in the "July Monarchy" of king Louis Philippe I. It is generally seen as a transitional period dominated by the conservative Orleanist doctrine in economic and foreign policies. The chief leaders included Prime Minister François Guizot. It went into exile during the reign of Emperor Napoleon III and collapsed with the establishment of the Third Republic in 1870.
