text: # Roman Catholic Diocese of Tuscanella
  
  The Diocese of Tuscanella (Latin: Tuscaniensis) was a Latin Church residential bishopric of the Catholic Church, in existence by the 7th century. Even at the time of the Lombard invasions, it belonged to the Duchy of Rome and was immediately subject to the Pope. The seat of the bishop was originally in the church of S. Maria, then in the church of S. Pietro, and after 1592 in the church of S. Giacomo.
  
  On 22 February 852 Pope Leo IV, in the bull Convenit apostolico, addressed to Bishop Virbono, confirmed the jurisdiction of the bishop over the churches and possessions of his diocese. This document is revealing, because it not only describes the towns and parishes dependent on the bishop (including Montalto, Tarquinia and Viterbo), but also details the boundaries of the diocese.
  
  From 1192 the diocese of Tuscanella and the diocese of Viterbo were in personal union (aeque principaliter).
  
  The diocese was suppressed in 1986.
  
  The name, though not the diocesan structure, was revived as the Latin Catholic titular see of Tuscania in 1991.
