Papal States

The Papal States were territories in central Italy under the direct sovereign rule of the Pope, formally established when the Frankish king Pepin III donated lands to the papacy in 756. For over a millennium the popes were not merely spiritual leaders but temporal rulers of a substantial Italian state, giving them the resources and independence to act as a major political force in European affairs. The papacy wielded enormous influence in medieval Europe, crowning emperors, launching crusades, and clashing with secular rulers in disputes like the Investiture Controversy. The papal court at Rome was a centre of Renaissance art and architecture under popes like Julius II and Leo X. Temporal power declined after Italian unification; the Papal States were progressively absorbed by the Kingdom of Italy between 1860 and 1870, leaving the Pope confined to the Vatican until the Lateran Treaty of 1929 established Vatican City.
