Italy became caught up in the nationalistic turmoils of the 19th century and twice gained and lost a short-lived independence. Rome became the focus of hopes of Italian reunification when the rest of Italy was reunited under the Kingdom of Italy with a temporary capital at Florence. In 1861 Rome was declared the capital of Italy even though it was still under the control of the Pope. During the 1860s the last vestiges of the Papal states were under French protection. And it was only when this was lifted in 1870, owing to the outbreak of the Franco-Prussian War, that Italian troops were able to capture Rome.
