Part of the process of Italian unification, the city's capture ended the millennial temporal rule of the popes over central Italy and allowed Rome to be designated the capital of the new nation . The appellation is also applied to Pius's successors through Pope Pius XI . </P> <P> As nationalism swept the Italian Peninsula in the 19th century, efforts to unify Italy were blocked in part by the Papal States, which ran through the middle of the peninsula and included the ancient capital of Rome . The Papal States were able to fend off efforts to conquer them largely through the pope's influence over the leaders of stronger European powers such as France and Austria . When Rome was eventually taken, the Italian government reportedly intended to let the pope keep the part of Rome west of the Tiber called the Leonine City as a small remaining Papal State, but Pius IX refused . One week after entering Rome, the Italian troops had taken the entire city save for the Apostolic Palace; the inhabitants of the city then voted to join Italy . </P>
