The Holy See of Rome, also called the Holy Roman Church, the Petrine See, the Apostolic See, and the Government of Vatican City, is the Pope's jurisdiction in his role as the Bishop of Rome, head of the worldwide Catholic Church, and head of state or sovereign of Vatican City. It includes the apostolic episcopal see of the Diocese of Rome, which has ecclesiastical jurisdiction over the Catholic Church, and sovereignty and governance over the city-state known as Vatican City.
The Roman Curia comprises the administrative institutions of the Holy See and the central body through which the affairs of the Roman Catholic Church are conducted. The Roman Curia is the institution which the Roman Pontiff ordinarily makes use of in the exercise of his supreme pastoral office and universal mission in the world. It is at the service of the Pope, successor of Peter, and of the Bishops, successors of the Apostles, according to the modalities that are proper to the nature of each one, fulfilling their function with an evangelical spirit, working for the good and at the service of communion, unity and edification of the Universal Church and attending to the demands of the world in which the Church is called to fulfill its mission.
Vatican City, officially the Vatican City State, is a landlocked independent country, city-state, microstate, and enclave within Rome, Italy. It became independent from Italy in 1929 with the Lateran Treaty, and it is a distinct territory under "full ownership, exclusive dominion, and sovereign authority and jurisdiction" of the Holy See, itself a sovereign entity under international law, which maintains the city-state's temporal power and governance, diplomatic, and spiritual independence. With an area of 49 hectares and as of 2023 a population of about 764, it is the smallest state in the world both by area and by population. As governed by the Holy See, Vatican City State is an ecclesiastical or sacerdotal-monarchical state ruled by the Pope, who is the bishop of Rome and head of the Catholic Church. The highest state functionaries are all Catholic clergy of various origins. After the Avignon Papacy (1309–1377) the popes have mainly resided at the Apostolic Palace within what is now Vatican City, although at times residing instead in the Quirinal Palace in Rome or elsewhere. The Vatican is also a metonym for the Holy See.
The politics of Vatican City take place in a framework of a theocratic absolute elective monarchy, in which the Pope, religiously speaking, the leader of the Catholic Church and Bishop of Rome, exercises ex officio supreme legislative, executive, and judicial power over the Vatican City as it is being governed by the Holy See, a rare case of non-hereditary monarchy.
The Lateran Treaty was one component of the Lateran Pacts of 1929, agreements between the Kingdom of Italy under King Victor Emmanuel III and the Holy See under Pope Pius XI to settle the long-standing Roman Question. The treaty and associated pacts were named after the Lateran Palace where they were signed on 11 February 1929, and the Italian parliament ratified them on 7 June 1929. The treaty recognized Vatican City as an independent state under the sovereignty of the Holy See. The Italian government also agreed to give the Roman Catholic Church financial compensation for the loss of the Papal States. In 1948, the Lateran Treaty was recognized in the Constitution of Italy as regulating the relations between the state and the Catholic Church. The treaty was significantly revised in 1984, ending the status of Catholicism as the sole state religion.
The Eastern Catholic Churches or Oriental Catholic Churches, also called the Eastern-Rite Catholic Churches, Eastern Rite Catholicism, or simply the Eastern Churches, are 23 Eastern Christian autonomous particular churches of the Catholic Church, in full communion with the Pope in Rome. Although they are distinct theologically, liturgically, and historically from the Latin Church, they are all in full communion with it and with each other. Eastern Catholics are a distinct minority within the Catholic Church; of the 1.3 billion Catholics in communion with the Pope, approximately 18 million are members of the eastern churches.
The Apostolic Palace is the official residence of the Pope, the head of the Catholic Church, located in Vatican City. It is also known as the Papal Palace, the Palace of the Vatican and the Vatican Palace.

The Diocese of Rome is the metropolitan diocese of the province of Rome, an ecclesiastical province in Italy. The first bishop of Rome was Saint Peter in the first century. The incumbent since 13 March 2013 is Pope Francis.

In 2023, Pope Francis returned it to its monastic purpose with an invitation to Benedictine nuns of the Abbey of St. Scholastica in Victoria, Argentina.
