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.
Habang unti-unting natatamo ng iglesya ng Romano Katolika ang higit na kapangyarihan at pamamahala sa 10 bansa-estado na ito ng Europa, malinaw na lahat maliban sa tatlo sa mga bansa nito (ang Heruli, Vandals, at Ostrogoths) ay sang-ayon, o sumuko sa relihiyon at kapamahalaan ng Katoliko.
