As the Roman Catholic church gradually gained more power and control over these 10 nation-states of Europe, it became evident that all but three of these nations -- the Heruli, Vandals, and Ostrogoths -- were in favor of, or yielded to, the Catholic religion and authority.
Kadiri ambavyo Kanisa Katoliki la Kirumi kwa taratibu lilipata mamlaka zaidi na utawala juu ya mataifa haya 10 ya kiserikali ya Ulaya, ilidhihirika wazi kwamba yote isipokuwa mataifa haya matatu (Heruli, Vandals, na Ostrogoths) yalipendelea, au yalijitoa kwa, mamlaka ya dini ya Kikatoliki.
