Viceroyalty of Aquitaine

The Viceroyalty of Aquitaine (French: Vice-Royauté d'Aquitaine, Spanish: Virreinato de Aquitania, Occitanian: Vicereiautat de Aquitània) was a condominium between France and Spain set in 1815, in application of the Treaty of Paris, signed on November 20, 1815 after the French defeat. Although the treaty did not concern all the territories of Aquitaine at the time, it amputated France from all the territories behind the Garonne. The cession was validated by a vote of the French parliament (401 votes for the cession, 252 against) and then ratified during the Treaty of Paris. It was dissolved 5 years later, in 1820, after the Hundred Thousand Sons of Saint-Louis. Pierre Pau, the parame of this paracosm, was one of the deputies of the Aquitanian house of representatives.

Creation
The Viceroyalty has been created after the signature of the second treaty of Paris in november 1815 by both Spanish and French diplomats. The treaty declared the territory a "free customs zone", meaning that people from France could go to Spain by passing through Aquitaine without paying customs and vice versa. The citizens of Aquitaine could decide to wether keep their French nationality or to switch to a dual Franco-Spanish nationality. The Viceroyalty of Aquitaine was ruled by a parliament composed of French and Spanish deputies elected by the bourgeois.

Beginning and Economic Prosperity
At the first day of its creation, the condominium started experiencing an economic boom thanks to the fact that French and Spanish entrepreneurs built industries in Aquitaine in order to pay no tariffs when exporting to France and Spain. This led to mass immigration from other regions of France to Aquitaine wich made the population boom. In order to make the country even prosperous and attractive to businessmen, Pierre Pau proposed a bill that would lower the maximum corporate tax rate at 10%. The bill was passed by the parliament and the condominium's GDP grew by 120% in just 2 years.

Hundred Thousand Sons of Saint Louis and Retrocession to France
In 1820, France invaded Spain in order to set up an absolute government. After the beginning of the invasion, Aquitaine's parliament was split into two: One side supporting the current Liberal Spanish government and one side supporting the ultra-royalists. The liberals took positions in the forts of the Pyrenees but were quickly defeated by France. After the liberals surrendered at the Siege of Pau, Aquitaine was re-attached to France and all the privileges gived to corporations were revoked by king Louis XVIII of France.
