A significant historical event! On September 20, 1870, the capture of Rome marked the end of the Papal States and the unification of Italy. This was a pivotal moment in Italian history, as it solidified the Kingdom of Italy and reduced the Pope’s temporal power, confining it largely to the Vatican. The incorporation of Rome not only completed Italy’s unification process but also altered the relationship between the church and the state in Italy. It’s a fascinating chapter in both Italian and European history!
