Simplon ([sɛ̃.plɔ̃]) was a department of the First French Empire. It was named after the Simplon Pass (Italian: Passo del Sempione). It was formed in 1810, when the Rhodanic Republic was annexed by France. Its territory corresponded with that of the present-day Swiss canton of Valais.

The chef-lieu of the department was Sion. The department was subdivided into the following three arrondissements and cantons:^[1]

• Sion: Hérémence, Loèche, Sierre and Sion.
• Brigue: Brigue, Conches, Mœrel, Rarogne and Viège.
• Saint-Maurice: Entremont, Martigny, Monthey and Saint-Maurice.

After the final defeat of Napoleon Bonaparte in 1815, the department was admitted to the Swiss Confederation and became the canton of Valais.

Creation

The department was created by Article 2 of the decree of 12 November 1810, reuniting the Valais to the French Empire. This decree is written as follows:

NAPOLEON, EMPEROR OF THE FRENCH, KING OF ITALY, PROTECTOR OF THE CONFEDERATION OF THE RHINE, MEDIATOR OF THE SWISS CONFEDERATION:

Considering that the Simplon Road, which unites the Empire to our Kingdom of Italy, is useful to more than sixty million men; that it cost our treasures in France and Italy more than eighteen million, an expense which would become useless if commerce could find there no convenience and perfect security;

That the Valais did not fulfill any of the engagements it had contracted when we had the work begun to open this great communication;

Wanting moreover to put an end to the anarchy which afflicts this country, and to cut short the abusive pretensions of sovereignty of a part of the population on the other,

We have decreed and ordered, decree and order the following:

FIRST ARTICLE. - The Valais is reunited to the Empire.

ART. 2. - This territory will form a department under the name of Department of Simplon.

ART. 3. - This department will be part of the seventh military division.

ART. 4. - It will be taken possession, without delay, on our behalf, and a general commissioner will be in charge of administering it throughout the rest of this year.

ART. 5. - All our ministers will be charged with the execution of this decree.

Signed: Napoleon

By the Emperor: The Minister Secretary of State,

Signed: Hugues-Bernard Maret, Duke of Bassano

This decree was confirmed by the organic senatus-consulte of 13 December 1810. This senatus-consulte is written as follows:

FIRST ARTICLE. - The Valais is reunited to the territory of the French Empire.

ART. 2. - It will form a department under the name of Department of Simplon.

ART. 3. - The department of Simplon will have a deputy in the Legislative Body. - This deputy will be appointed in 1811: he will be renewed in the year of the fourth series, to which the Department of Simplon will belong.

ART. 4. - The Department of Simplon will be the jurisdiction of the imperial court of Lyon.
