Roman Catholic Diocese of Lausanne, Geneva and Fribourg in a papal brief of 20 September 1819, the city of Geneva and twenty parishes belonging to the old Diocese of Geneva (which in 1815 had become Swiss) to the See of Lausanne. The bishop (in 1815 Petrus Tohias Yenni) retained his residence at Fribourg, and since 1821 has borne the title and arms of the Bishops of Lausanne and Geneva. His vicar general resides at Geneva, and is always parish priest of that city. Bishop Yenni died on 8 December 1845 and was succeeded by Etienne Marilley. Deposed in 1848 by the Cantons of Berne, Geneva, Vaud and Neuchâtel,
Amadeus II of Geneva Amadeus II of Geneva Amadeus II (died 22 May 1308) was the Count of Geneva, which included the Genevois, but not the city of Geneva, from 1280. He was the second son of Count Rudolf and succeeded his heirless brother Aymon II. In June 1282 at Versoix, Amadeus and Béatrice “la Grande Dauphine”, the dowager Countess of Albon and regent for her son John I, came to an agreement whereby all the places that Amadeus' father and grandfather, William II, had been forced to cede to Peter “the Little Charlemagne” in 1250 and 1260—the so-called "gagerie"—would be returned to Geneva.
