When Napoleon returned to Paris the city was decorated with large arches, with banners proclaiming "To Napoleon III, emperor". In response to officially inspired requests for the return of the empire, the Senate scheduled another referendum for 21–22 November 1852 on whether to make Napoleon emperor. After an implausible 97 percent voted in favour (7,824,129 votes for and 253,159 against, with two million abstentions), on 2 December 1852—exactly one year after the coup—the Second Republic was officially ended, replaced by the Second French Empire. Prince-President Louis Napoleon Bonaparte became Napoleon III, Emperor of the French. His regnal name treats Napoleon II, who never actually ruled, as a true Emperor (he had been briefly recognized as emperor from 22 June to 7 July 1815). The 1852 constitution was retained; it concentrated so much power in Napoleon's hands that the only substantive change was to replace the word "president" with the word "emperor".
