Pope Vitalian
Pope Vitalian (Latin: Vitalianus; died 27 January 672) was the bishop of Rome from 30 July 657 to his death. His pontificate was marked by the dispute between the papacy and the imperial government in Constantinople over Monothelitism, which Rome condemned. Vitalian tried to resolve the dispute and had a conciliatory relationship with Emperor Constans II, who visited him in Rome and gave him gifts. Vitalian's pontificate also saw the secession of the Archbishopric of Ravenna from the papal authority.
