A referendum on re-establishing the Empire was held in France on 21 and 22 November 1852. Voters were asked whether they approved of the re-establishment of the Empire in the person of Louis Napoléon Bonaparte and his family. It was approved by 97% of voters with an 80% turnout. After the plebiscite, Louis Napoléon assumed the style "Napoleon III, Emperor of the French." As with all other plebiscites under Napoleon III (and Napoleon I before him), the results were blatantly rigged and only served to use the façade of democracy to legitimize their rule.
