Geneva

The bishop is the lord of the city of Geneva.

By the accord of Seyssel (1124) the count of Geneva recognised Bishop Humbert of Grammont as sole lord of the whole city, and on 17 January 1154 at Speyer Frederick Barbarossa invested Bishop Ardutius as a prince of the Empire, confirmed again in 1162. The bishops have struck coin since 1020-1030. The counts of Geneva, who hold the country round about (the Genevois), are their constant rivals; the counts of Savoy will be the greater danger later in the century.

medium

Bishop 1185-1205 (en.wikipedia list), followed by Bernard Chabert. In September 1198 he and his namesake of Sion issued a joint act for Saint-Maurice (Marburg charter repository, title only). His family and his quarrels with the count are not pinned: the HLS article on him could not be read (the fetch proxy refused it).

What it holds

  • Geneva: lordship of the city, high justice, mint (since 1020-1030), tolls and market
  • Episcopal lands outside the city, later organised as the mandements of Jussy, Peney and Thiez (their castles are thirteenth-century; tenure of the land in 1200 is likely but not pinned)

How it was acquired

Rights of the see from the Burgundian kings; the Seyssel accord of 1124 with the count; imperial investiture of 1154 (and 1162) making the bishop a direct prince of the Empire.

How things stand that morning

The bishop holds the city; the count holds the country round it and contests the bishop's rights when he can. The bishop's neighbour at Lausanne, Roger, has just ended (1195) a war with the counts of Geneva.

Wealth

The bridge over the Rhone at the lake's outlet and its tolls; the city market; the mint.

Threats

  • The counts of Geneva
  • The rise of Savoy north and south of the lake

Advocates and rivals

The counts of Geneva, rivals for the city and lords of the Genevois; the Zaehringen, whose claim to stand between the Burgundian sees and the crown Barbarossa set aside for Geneva; the counts of Savoy beyond.

Places of note

  • Cathedral of Saint-Pierre: Seat of the bishop, rebuilt from about 1160

Where the sources disagree

Evidence: The constitutional basis (1124, 1154, 1162) is in the HLS and en.wikipedia; the bishop and the state of the quarrel with the count in 1200 are thin.

On the map: The city is drawn as the modern municipality of Geneva. The outlying mandements are drawn as later held; Thiez, the third mandement, in the Faucigny, is left out.
