The French Second Republic (French: Deuxième république française or La II République), officially the French Republic (République française), was the second republican formation of the government of France. The republic existed from 1848, when the monarchy fell, until its dissolution only four years later in 1852 upon the proclamation of the second French Empire.
Following the final defeat of Napoleon Bonaparte at the Battle of Waterloo, in June 1815, France had been reconstituted into a monarchy known as the Bourbon Restoration. After a brief period of revolutionary turmoil in 1830, royal power was again secured in the "July Monarchy", governed under principles of moderate conservatism and improved relations with the United Kingdom.
