After Italian Unification and the abrupt (and unofficial) end of the First Vatican Council in 1870 because of the outbreak of the Franco-Prussian War, the ultramontanist movement and the opposing conciliarism became obsolete to a large extent. However, some very extreme tendencies of a minority of adherents to ultramontanism – especially those attributing to the Roman pontiff, even in his private opinions, absolute infallibility even in matters beyond faith and morals, and impeccability – survived and were eagerly used by opponents of the Catholic Church and papacy before the Second Vatican Council (1962–1965) for use in their propaganda. These extreme tendencies, however, were never supported by the First Vatican Council's dogma of 1870 of papal infallibility and primacy, but were rather inspired by erroneous private opinions of some Roman Catholic laymen who tend to identify themselves completely with the Holy See.
