At that same referendum, a new constitution was approved. Formally enacted in January 1852, the new document made Louis-Napoléon president for 10 years, with no restrictions on re-election. It concentrated virtually all governing power in his hands. However, Louis-Napoléon was not content with merely being an authoritarian president. Almost as soon as he signed the new document into law, he set about restoring the empire. In response to officially inspired requests for the return of the empire, the Senate scheduled a second referendum in November, which passed with 97 percent support. As with the December 1851 referendum, most of the "yes" votes were manufactured out of thin air.
