After the unification of Italy, the new state annexed the Papal States after Germany defeated France, which had protected the pope's interests, in the Franco-Prussian War (1870–1871). The popes refused to leave, declaring themselves "Prisoners of the Vatican," until Benito Mussolini signed agreements in 1929 granting the Church special privileges in Italy and a cash settlement. The Vatican was given independence under papal rule. Since that time, the Vatican has been an independent state that sends and receives ambassadors.
