With the conquest of Vaud by Bern in 1536, Cully came under the administration of the Bailiwick of Lausanne. After the collapse of the Ancien régime, the village belonged from 1798 to 1803 during the Helvetic Republic to the Canton of Léman. In 1798 Cully Lavaux became the capital of the district, as it was in the central part of the district. It was not until 1824, that Cully attained the status of an independent political community. A project to merge the independent municipalities Cully, Epesses, Riex, Grandvaux, and Villette (Lavaux) failed in a vote on 27 February 2005 due to the resistance of the population of Grandvaux. The project is therefore not being pursued.
