The Author analyses the itinerary which brought the Italian Bishops away from the fragmented situation characterising them the outset of the Italian Unity, towards a new, Unitarian national profile. The process which made Bishops converge to Rome and distance themselves from the former pre-Unity capitals, took place un-der the guidance of the Holy See, along with the process of ecclesiastic centralisa-tion stressing the role of the pontiff as leader of the Italian Church, at least until 1978. Such a process reached its apex with Pius XII. Albeit not linearly, the church structure seemed to follow the same process undergoing within the State. Staffing Southern Dioceses with priests coming from Northern Italy is an example. During the Twentieth Century, thrice the Pope was from Lombardy (Pius XI, John XXIII and Paul VI), while the top hierarchy of the Italian Bishop’s Conference never en-listed a Southerner as President or Secretary-General. With the pontificate of John Paul II, we begin to see a Unitarian national episcopate, with proper structures, in-stitutions, resources and financing means.
