In 1870, Prussia went to war with France, igniting the Franco-Prussian War. To keep the large Prussian Army at bay, France abandoned its positions in Rome – which protected the remnants of the Papal States and Pius IX – in order to fight the Prussians. Italy benefited from Prussia's victory against France by being able to take over the Papal States from French authority. Rome was captured by the Kingdom of Italy after several battles and guerrilla-like warfare by Papal Zouaves and official troops of the Holy See against the Italian invaders. Italian unification was completed and shortly afterward Italy's capital was moved to Rome. Economic conditions in the united Italy were poor. There were no industry or transportation facilities, extreme poverty (especially in the ""Mezzogiorno""), high illiteracy and only a small percent of wealthy Italians had the right to vote. The unification movement had largely been dependent on the support of foreign powers and remained so afterwards.
