Kingdom of Italy

In the 19th century, Rome again became the focus of a power struggle with the rise of the Kingdom of Italy, which wished to see a reunification of Italy. The Papal States remained in control of Rome under French protection, but with the outbreak of the Franco-Prussian War of 1870, French troops were forced to abandon Rome, leaving it clear for the Kingdom of Italy to capture. Rome became the capital of Italy, and has remained such ever since.
