King Rudolphe I of Burgundy granted the Church of Lausanne the privilege of electing its own bishop on 28 January 895.
[2][3] It is claimed that the bishops of Lausanne[4] were granted the title of Prince of the Holy Roman Empire in 1270.
[5] The deed of grant is published by Jean Joseph Hisely in his work on the comtes de Genevois, but it bears the date 28 September 1273, not 1270.
It states that the grant was requested by Pope Gregory X in person, on the very day on which he presided at the consecration of the cathedral of Lausanne.
[11] Bishop Sébastien de Montfalcon fled into exile, first in Évian-les-Bains, and then in Burgundy.
