Pada periode modern awal, dalam menghadapi meningkatnya kekuatan sekuler di Eropa, Gereja Katolik berjuang untuk mempertahankan peran politis dan religius tradisionalnya di negara-negara mayoritas Katolik. Sebagai akibat dari perjuangan ini, di beberapa negara mayoritas Katolik (terutama di antara individu-individu dengan pandangan politis sekuler tertentu) timbul sikap bermusuhan terhadap kekuatan politis, sosial, spiritual, dan religius yang cukup besar dari Paus maupun kaum klerus dalam bentuk anti-klerikalisme.
