It was established on 2 December 1852 by Louis-Napoléon Bonaparte, president of France under the French Second Republic, who proclaimed himself Emperor of the French as Napoleon III. The period was one of significant achievements in infrastructure and economy, while France reasserted itself as a dominant power in Europe.

Second French Empire in Depth

History

On 2 December 1851, Louis-Napoléon Bonaparte, who had been elected President of the Republic in 1848, staged a coup d'état by dissolving the National Assembly without having the constitutional right to do so. He thus became sole ruler of France, and re-established universal male suffrage, previously abolished by the Assembly. His decisions were popularly endorsed by a referendum later that month that attracted 92 percent support.

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.

Structure of government

The structure of the French government during the Second Empire was little changed from the First. Emperor Napoleon III stressed his own imperial role as the foundation of the government; if government was to guide the people toward domestic justice and external peace, it was his role as emperor, holding his power by universal male suffrage and representing all of the people, to function as supreme leader and safeguard the achievements of the revolution.

He had so often, while in prison or in exile, chastised previous oligarchical governments for neglecting social questions that it was imperative France now prioritise their solutions. His answer was to organise a system of government based on the principles of the "Napoleonic Idea".
