سقوط الإمبراطورية الرومانية الغربية
The Archbishopric of Spalathon or Spalatum (also "Salona", ) was a Christian archbishopric with seat in Salona, Dalmatia (modern Split, Croatia) in the early Middle Ages. After the Fall of the Western Roman Empire it recognised the supremacy of the Patriarch of Constantinople. During this period, the Salona archdiocese, in year 590, gained territory from the suppressed Roman Church of Makarska.
