Papal States in the context of "Pope Sixtus IV"

The Kingdom of the Two Sicilies (Italian: Regno delle Due Sicilie) was a kingdom in Southern Italy from 1816 to 1861 under the control of the House of Bourbon-Two Sicilies, a cadet branch of the Spanish Bourbons. The kingdom was the largest sovereign state by population and land area in Italy before the Italian unification, comprising Sicily and most of the area of today's Mezzogiorno (southern Italy) and covering all of the Italian peninsula south of the Papal States.

The kingdom was formed when the Kingdom of Sicily merged with the Kingdom of Naples, which was officially also known as the Kingdom of Sicily. Since both kingdoms were named Sicily, they were collectively known as the "Two Sicilies" (Utraque Sicilia, literally "both Sicilies"), and the unified kingdom adopted this name. The king of the Two Sicilies was overthrown by Giuseppe Garibaldi in 1860, after which the people voted in a plebiscite to join the Kingdom of Sardinia. The annexation of the Kingdom of the Two Sicilies completed the first phase of Italian unification, and the new Kingdom of Italy was proclaimed in 1861.

Vatican City, officially the Vatican City State (Italian: Stato della Città del Vaticano; Latin: Status Civitatis Vaticanae), often shortened as the Vatican, is a landlocked sovereign city-state. Ruled by the pope, it is an enclave within Rome and serves as the administrative centre of the Catholic Church. Vatican City is governed by the See of Rome, commonly known as the Holy See, itself a sovereign entity under international law, which maintains its temporal power, governance, diplomacy, and spiritual independence. Vatican is also used as a metonym for the Holy See, which is the central governing body of the Catholic Church and Vatican City, comprising the pope and the Roman Curia. The independent state of Vatican City came into existence in 1929 via the Lateran Treaty between the Holy See and the Kingdom of Italy, which spoke of it as a new creation, not as a vestige of the much larger Papal States (756–1870), which had previously encompassed much of Central Italy.

With an area of 48.99 hectares (121 acres) and a population of about 882 in 2024, it is the smallest sovereign state in the world both by area and by population. It is among the least populated capitals in the world. 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. The Holy See dates to early Christianity and is the principal episcopal see of the Catholic Church, which in 2018 had about 1.329 billion baptized Catholics in the world, in the Latin Church and 23 Eastern Catholic Churches. 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 pope is the bishop of Rome and the head of the worldwide Catholic Church. He is also known as the supreme pontiff, Roman pontiff, or sovereign pontiff. From the 8th century until 1870, the pope was the sovereign or head of state of the Papal States, and since 1929 of the much smaller Vatican City State. From a Catholic viewpoint, the primacy of the bishop of Rome is largely derived from his role as the apostolic successor to Saint Peter, to whom primacy was conferred by Jesus, who gave Peter the Keys of Heaven and the powers of "binding and loosing", naming him as the "rock" upon which the Church would be built. The current pope is Leo XIV, who was elected on 8 May 2025 on the second day of the 2025 papal conclave.

While his office is called the papacy, the jurisdiction of the episcopal see is called the Holy See. The word see comes from the Latin for 'seat' or 'chair' (sede, referring in particular to the one on which the newly elected pope sits during the enthronement ceremony). The Holy See is a sovereign entity under international law; it is headquartered in the distinctively independent Vatican City, a city-state which forms a geographical enclave within the conurbation of Rome. It was established by the Lateran Treaty in 1929 between Fascist Italy and the Holy See to ensure its political and spiritual independence. The Holy See is recognized by its adherence at various levels to international organizations and by means of its diplomatic relations and political accords with many independent states.

The history of Rome includes the history of the city of Rome as well as the civilisation of ancient Rome. Roman history has been influential on the modern world, especially in the history of the Catholic Church, and Roman law has influenced many modern legal systems. Roman history can be divided into the following periods:

• Pre-historical and early Rome, covering Rome's earliest inhabitants and the legend of its founding by Romulus
• The period of Etruscan dominance and the regal period, in which, according to tradition, Romulus was the first of seven kings
• The Roman Republic, which commenced in 509 BC when kings were replaced with rule by elected magistrates. The period was marked by vast expansion of Roman territory. During the 5th century BC, Rome gained regional dominance in Latium. With the Punic Wars from 264 to 146 BC, ancient Rome gained dominance over the Western Mediterranean, displacing Carthage as the dominant regional power.
• The Roman Empire followed the Republic, which waned with the rise of Julius Caesar, and by all measures concluded after a period of civil war and the victory of Caesar's adopted son, Octavian, in 27 BC over Mark Antony.
• The Western Roman Empire collapsed in 476 after the city was conquered by the Ostrogothic Kingdom. Consequently, Rome's power declined, and it eventually became part of the Eastern Roman Empire, as the Duchy of Rome, from the 6th to 8th centuries. At this time, the city was reduced to a fraction of its former size, being sacked several times in the 5th to 6th centuries, even temporarily depopulated entirely.
• Medieval Rome is characterised by a break with Constantinople and the formation of the Papal States. The Papacy struggled to retain influence in the emerging Holy Roman Empire, and during the saeculum obscurum, the population of Rome fell to as low as 30,000 inhabitants. Following the East–West Schism and the limited success in the Investiture Controversy, the Papacy did gain considerable influence in the High Middle Ages, but with the Avignon Papacy and the Western Schism, the city of Rome was reduced to irrelevance, its population falling below 20,000. Rome's decline into complete irrelevance during the medieval period, with the associated lack of construction activity, assured the survival of very significant ancient Roman material remains in the centre of the city, some abandoned and others continuing in use.
• The Roman Renaissance occurred in the 15th century, when Rome replaced Florence as the centre of artistic and cultural influence. The Roman Renaissance was cut short abruptly with the devastation of the city in 1527, but the Papacy reasserted itself in the Counter-Reformation, and the city continued to flourish during the early modern period. Rome was annexed by Napoleon and was part of the First French Empire from 1809 to 1814.
• Modern history, the period from the 19th century to the present. Rome came under siege again after the Allied invasion of Italy and was bombed several times. It was declared an open city on 14 August 1943. Rome became the capital of the Italian Republic (established in 1946). With a population of 4.4 million (as of 2015; 2.9 million within city limits), it is the largest city in Italy. It is among the largest urban areas of the European Union and classified as a global city.

Pope Julius II (Latin: Iulius II; Italian: Giulio II; born Giuliano della Rovere; 5 December 1443 – 21 February 1513) was head of the Catholic Church and ruler of the Papal States from 1503 to his death, in February 1513. Nicknamed the Warrior Pope, the Battle Pope or the Fearsome Pope, it is often speculated that he had chosen his papal name not in honor of Pope Julius I but in emulation of Julius Caesar. One of the most powerful and influential popes, Julius II was a central figure of the High Renaissance and left a significant cultural and political legacy. As a result of his policies during the Italian Wars, the Papal States increased their power and centralization, and the office of the papacy continued to be crucial, diplomatically and politically, during the entirety of the 16th century in Italy and Europe.

In 1506, Julius II established the Vatican Museums and initiated the rebuilding of the St. Peter's Basilica. The same year he organized the famous Swiss Guard for his personal protection and commanded a successful campaign in Romagna against local lords. The interests of Julius II lay also in the New World, as he ratified the Treaty of Tordesillas, establishing the first bishoprics in the Americas and beginning the Catholicization of Latin America. In 1508, he commissioned the Raphael Rooms and Michelangelo's paintings in the Sistine Chapel.

The history of Italy in the Middle Ages can be roughly defined as the time between the collapse of the Western Roman Empire and the Italian Renaissance. Late antiquity in Italy lingered on into the 7th century under the Ostrogothic Kingdom and the Byzantine Empire under the Justinian dynasty, the Byzantine Papacy until the mid 8th century. The "Middle Ages" proper begin as the Byzantine Empire was weakening under the pressure of the Muslim conquests, and most of the Exarchate of Ravenna finally fell under Lombard rule in 751. From this period, former states that were part of the Exarchate and were not conquered by the Lombard Kingdom, such as the Duchy of Naples, became de facto independent states, having less and less interference from the Eastern Roman Empire.

Lombard rule ended with the invasion of Charlemagne in 773, who established the Kingdom of Italy and the Papal States in large parts of Northern and Central Italy. This set the precedent for the main political conflict in Italy over the following centuries, between the Pope and the Holy Roman Emperor, culminating with conflict between Pope Gregory VII and Henry IV and the latter's "Walk to Canossa" in 1077.

The Italian Renaissance (Italian: Rinascimento [rinaʃʃiˈmento]) was a period in Italian history during the 15th and 16th centuries. The period and place are known for the initial development of the broader Renaissance culture that spread from Italy to the rest of Europe (and also to extra-European territories ruled by colonial powers or where Christian missionaries and/or traders were active). The period was one of transition: it sits between the Middle Ages and the modern era. Proponents of a "long Renaissance" argue that it started around the year 1300 and lasted until about 1600. In some fields, a Proto-Renaissance, beginning around 1250, is typically accepted. The French word renaissance (corresponding to rinascimento in Italian) means 'rebirth', and defines the period as one of cultural revival and renewed interest in classical antiquity after the centuries during what Renaissance humanists labelled as the "Dark Ages". The Italian Renaissance historian Giorgio Vasari used the term rinascita ('rebirth') in his Lives of the Most Excellent Painters, Sculptors, and Architects in 1550, but the concept became widespread only in the 19th century, after the work of scholars such as Jules Michelet and Jacob Burckhardt.

The Renaissance began in Tuscany in Central Italy and centered in the city of Florence. The Florentine Republic, one of the several city-states of the peninsula, rose to economic and political prominence by providing credit to European monarchs and by laying the groundwork for developments in capitalism and banking. Renaissance culture later spread to Venice, the heart of a Mediterranean empire controlling trade routes with the east since its participation in the Crusades and following the journeys of Marco Polo between 1271 and 1295. Thus Italy renewed contact with the remains of ancient Greek culture, which provided humanist scholars with new texts. Finally the Renaissance had a significant effect on the Papal States and on Rome, largely rebuilt by humanist and Renaissance popes, such as Julius II and Leo X, who frequently became involved in Italian politics, in arbitrating disputes between competing colonial powers and in opposing the Protestant Reformation, which started c. 1517.

Lazio (UK: /ˈlætsioʊ/ LAT-see-oh, US: /ˈlɑːt-/ LAHT-; Italian: [ˈlattsjo]) or Latium (/ˈleɪʃiəm/ LAY-shee-əm, US also /-ʃəm/ -⁠shəm; from the original Latin name, pronounced [ˈɫati.ũː]) is one of the 20 administrative regions of Italy. Situated in the central peninsular section of the country, it has 5,714,882 inhabitants and a GDP of more than €212 billion per year, making it the country's second most populated region and second largest regional economy after Lombardy. The capital of Lazio is Rome, which is the capital city of Italy.

Lazio was the home of the Etruscan civilization, then stood at the center of the Roman Republic, of the Roman Empire, of the Papal States, of the Kingdom of Italy and of the Italian Republic. Lazio boasts a rich cultural heritage. Great artists and historical figures lived and worked in Rome, particularly during the Italian Renaissance period.

Italy has been inhabited by humans since the Paleolithic. During antiquity, there were many peoples in the Italian peninsula, including Etruscans, Latins, Samnites, Umbri, Cisalpine Gauls, Greeks in Magna Graecia and others. Most significantly, Italy was the cradle of the Roman civilization. Rome was founded as a kingdom in 753 BC and became a republic in 509 BC. The Roman Republic then unified Italy forming a confederation of the Italic peoples and rose to dominate Western Europe, Northern Africa, and the Near East. The Roman Empire, established in 27 BC, ruled the Mediterranean region for centuries, contributing to the development of Western culture, philosophy, science and art.

During the early Middle Ages, Italy experienced the succession in power of Ostrogoths, Byzantines, Longobards and the Holy Roman Empire and fragmented into numerous city-states and regional polities, a situation that would remain until the unification of the country. These polities and the maritime republics, in particular Venice and Genoa, rose to prosperity. Eventually, the Italian Renaissance emerged and spread to the rest of Europe, bringing a renewed interest in humanism, science, exploration, and art with the start of the modern era. In the medieval and early modern era, Southern Italy was ruled by the Norman, Swabian and Angevin dynasties and the Aragonese, French and Spanish crowns. Central Italy was largely part of the Papal States.
