Collegium Pontificum

The Collegium Pontificum was a group of high-ranking priests and diplomats established by the Vatican in the 16th century to advise the Pope and handle diplomatic affairs. Its purpose was to strengthen the Church’s influence and manage relations with other states and religious entities. Over time, it became an essential part of the Papal diplomatic service, coordinating efforts such as negotiations, treaties, and appointments. The institution helped professionalize the Vatican’s diplomacy, making it a more organized and effective tool for the Church’s international relations.
