Papal States

Italian state from 756 to 1870

The Papal States, officially the State of the Church, were a conglomeration of territories on the Italian Peninsula under the direct sovereign rule of the pope from 756 to 1870. They were among the major Italian states from the 8th century until the unification of Italy, which took place between 1859 and 1870, culminating in their incorporation into the Kingdom of Italy.
