Period 17 of 20 · 1815–1878
Ultramontanism and Vatican I
Nineteenth-century Catholics faced nationalism, liberal constitutionalism, anti-clerical legislation and the end of papal temporal rule. Ultramontane unity around Rome culminated in Vatican I's definitions. The council's suspension left much of its program unfinished but did not weaken the authority of the constitutions actually promulgated.

Pastor aeternus and Papal Primacy
Pastor aeternus defined universal papal primacy and the conditions of ex cathedra infallibility. The definition did not make every papal act infallible; it carefully specified subject, act, object and obligation.
High documentary densityRome
Suspension of Vatican I
The Franco-Prussian War and Italian capture of Rome made continuation impracticable. Pius IX prorogued the council sine die rather than formally closing it; later popes did not reconvene it, and Vatican II was a distinct council.
