One of the major factors that contributed to Italy not being unified after the congress of Vienna was the impact of foreign influence. Before the restoration of the old regime in Italy state boundaries were rearranged a number of times, ending up with a division of the peninsula into only three parts instead of eleven states. One third, including Piedmont, was annexed to France, one third became the Kingdom of Italy, and Napoleon's brother, Joseph, as the Kingdom of Naples, ruled the remainder.

But when the Pope returned he was intent on restoring temporal, as well as spiritual, control. The Papal States were divided into seventeen provinces, five of which were under the authority of Papal Legates, or Cardinals, who acted as provincial governors. The remainder, which were nearer Rome,
