Léman (department)
Léman was a department of the French First Republic and French First Empire. Its name came from the French name of Lake Geneva, Lac Léman. It was formed in 1798, when the Republic of Geneva was annexed by the French Republic. Léman also included districts that were previously part of the departments of Mont-Blanc and Ain. Its territory corresponded with the present Swiss canton of Geneva and parts of the present French departments of Ain and Haute-Savoie.
The Chef-lieu of the department was Genève. The department was subdivided into the following three arrondissements and cantons:
- Genève: Carouge, Chêne-Thônex, Collonge, Frangy, Genève, Gex, Reignier and Saint-Julien.
- Bonneville: Bonneville, Chamonix, Cluses, Megève, La Roche, Sallanches, Samoëns, Taninges and Viuz-en-Sallaz.
- Thonon: Douvaine, Évian, Saint-Jean-d'Aulps and Thonon.
