Papal States

The Papal States, officially the State of the Church, were a series of territories in the Italian Peninsula under the direct sovereign rule of the pope from 756 until 1870. They were among the major states of Italy from the 8th century until the unification of Italy, between 1859 and 1870. The state had its origins in the rise of Christianity throughout Italy, and with it the rising influence of the Christian Church. By the mid-8th century, with the decline of the Byzantine Empire in Italy, the Papacy became effectively sovereign. Several Christian rulers, including the Frankish kings Charlemagne and Pepin the Short, further donated lands to be governed by the Church. During the Renaissance, the papal territory expanded greatly and the pope became one of Italy's most important secular rulers as well as the head of the Church. At their zenith, the Papal States covered most of the modern Italian regions of Lazio (which includes Rome), Marche, Umbria and Romagna, and portions of Emilia. These holdings were considered to be a manifestation of the temporal power of the pope, as opposed to his ecclesiastical primacy. By 1861, much of the Papal States' territory had been conquered by the Kingdom of Italy. Only Lazio, including Rome, remained under the pope's temporal control. In 1870, the pope lost Lazio and Rome and had no physical territory at all, except the Leonine City of Rome, which the new Italian state did not occupy militarily, despite annexation of Lazio. In 1929, the Italian fascist leader Benito Mussolini, the head of the Italian government, ended the "Prisoner in the Vatican" problem involving a unified Italy and the Holy See by negotiating the Lateran Treaty, signed by the two parties. This treaty recognized the sovereignty of the Holy See over a newly created international territorial entity, a city-state within Rome limited to a token territory which became the Vatican City. Name The Papal States were also known as the Papal State (although the plural is usually preferred, the singular is equally correct as the polity was more than a mere personal union). The territories were also referred to variously as the State(s) of the Church, the Pontifical States, the Ecclesiastical States, the Patrimony of St Peter or the Roman States (, also , , , and ; , also "papal rule"). To some extent the name used varied with the preferences and habits of the European languages in which it was expressed.
