historical flag of the city of Geneva, showing the Imperial Eagle and a Key of St. Peter (symbolizing the status of Geneva as Reichsstadt and as episcopal seat, respectively), in use since the 15th century. The flag of the medieval bishopric of Geneva showed two golden Keys of Peter in the red field of the imperial Blutbanner since 1293. The full heraldic achievement of Geneva includes a crest in the form of half a sun inscribed with JHS (for Jesus Hominum Salvator), and a scroll below the shield with the motto Post Tenebras Lux. The coat of arms of the city of Geneva was adopted as the cantonal coat of arms upon the accession of Geneva as a city-canton to the restored Swiss Confederacy in 1815. Jura The separatist movement which eventually led to the canton's creation emerged in the 1940s, and the flag is a design by Paul Boesch, dated to 1943. The crozier symbolizes the former Prince-Bishopric of Basel, the seven stripes represent the seven districts of the Bernese Jura. It was officially recognized as a regional flag by Bern from the early 1950s. The canton of Jura was created in 1979 after a referendum, but only three of the seven districts opted to join. The seven stripes were retained in the cantonal flag regardless, and there remains some irredentism calling for a restored unity of all seven districts.
