During the Second Italian War of Independence, much of the Papal States had been conquered by the Piedmontese Army, and the new unified Kingdom of Italy was created in March 1861, when the first Italian Parliament met in Turin. On 27 March 1861, the Parliament declared Rome the Capital of the Kingdom of Italy. However, the Italian government could not take its seat in Rome because it did not control the territory. In addition, a French garrison was maintained in the city by Napoleon III of France in support of Pope Pius IX, who was determined not to hand over temporal power in the States of the Church.
