After prior consultation of the hierarchy in ''[[Ubi primum (Pius IX, 1849)|Ubi primum]]'' (see above), Pius decisively acted on the century-old disagreement between [[Dominican Order|Dominicans]] and [[Franciscans]] regarding the [[Immaculate Conception]] of Mary, deciding in favour of the Franciscan view.{{sfn|Franzen|Bäumer|1988|p=340}} However, his defining this infallible [[dogma]] raised a question: Can a pope make such decisions without the authority of the bishops? This doctrine of [[papal infallibility]], enhancing the role of the papacy and decreasing the role of the bishops, became a topic of the First Vatican Council convened in 1869.{{sfn|Franzen|Bäumer|1988|p=340}}
