What are the “Papal States” I see often when reading Catholic history books? Especially in the 19th century.
After the fall of Rome, Italy, as well as the rest of Europe, fell apart into petty principalities. There were a number of reasons for that; not the least being the destruction of central authority and the coordination of societies. Fairly early on, the Pope became the de facto ruler of Rome and some outlying countryside, more or less by default. There was just no other authority extant other than various warlords and brigand bands. Lawlessness was incredibly rampant.
At a point, a convention arose that Pepin,the ruler of the Franks, donated a larger portion of the surrounding countryside to the Pope. That donation has been strongly questioned by modern historians. Pepin’s grandons, Charlemagne, who was far and away the most powerful ruler in Europe, including much of Italy, definitely did donate a substantial segment of central Italy to the Pope. That was the foundation of the “Papal States”.
For various reasons, Italy remained fragmented during the medieval and Renaissance periods; more so than the rest of Europe except, late on, in Germany, when the power of the Holy Roman Emperors (Germans) began to dissolve.
The Popes, then, were the temporal rulers of much of Central Italy right up to the late 19th Century, when Italy was united due to two Italian unificaiton movements that joined forces at that time. The Pope actually had a small army, which fought valiantly against the secular forces, but was overcome. That army was composed of Catholic men from all over the world, including the United States, but were, as I understand it, mostly Irish.
Ultimately, the Pope made an agreement with Italy during Mussolini’s reign. The Popes gave up all claim to the Papal States, and were given Vatican City as a separate “country” from Italy. I think Vatican City is about 100 acres. Also, I think a papal retreat in the Italian countryside was given to the Popes, absolutely. That remains the situation today.
The old Papal states were called “states” because Italy was traditionally divided into what had once been, and to a degree, still are, ethnic subdivisions of italy; the Romagna, Tuscany and others. The Papal States included more than one of those regions or “states”.
