During the unification of Italy in the mid-19th century, the Papal States resisted incorporation into the new nation, even as all the other Italian countries, except for San Marino, joined it; Camillo Cavour's dream of proclaiming the Kingdom of Italy from the steps of St. Peter's Basilica did not come to pass. The nascent Kingdom of Italy invaded and occupied Romagna (the eastern portion of the Papal States) in 1860, leaving only Latium in the pope's domains. Latium, including Rome itself, was occupied and annexed in 1870. For the following sixty years, relations between the Papacy and the Italian government were hostile, and the status of the pope became known as the "Roman Question".
