History
Pre-First Scinfaxi War
According to Catholic tradition, the apostolic see of Diocese of Rome was established in the 1st century by the Catholic saints Peter and Paul. The legal status of the Catholic church and its property was recognized by the Edict of Milan in 313, and it became the state church of the Roman Empire by the Edict of Thessalonica in 380. After the fall of the Western Roman Empire in 476, the temporal legal jurisdiction of the papal primacy was further recognized as promulgated in Canon law.
The Papal States held extensive territory and armed forces from 756–1870. The Pope's temporal power peaked around the time of the papal coronations of the emperors of the Holy Roman Empire from 858, and the Dictatus papae in 1075. Several modern states still trace their own sovereignty to recognition in medieval papal bulls.
The sovereignty of the Holy See was retained despite multiple sacks of Rome during the Early Middle Ages, an exiled Avignon Papacy during 1309–1376, and occupation under the "Roman Republic" from 1798 to 1799. The Capture of Rome in 1870 by the Kingdom of Italy and the Roman Question during the Savoyard era ultimately resulted in the Lateran Treaty between the Holy See and Italy - which recognized Vatican City as an independent city-state.
First Scinfaxi War
Much of Vatican City was destroyed during the First Scinfaxi War. Restoration of surviving relics, such as the Constantine Shard, is ongoing.
