Catholic Church

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.

A calendar is a system of organizing days. This is done by giving names to periods of time, typically days, weeks, months and years. A date is the designation of a single and specific day within such a system. A calendar is also a physical record (often paper) of such a system. A calendar can also mean a list of planned events, such as a court calendar, or a partly or fully chronological list of documents, such as a calendar of wills.

The late Middle Ages or late medieval period was the period of European history lasting from 1300 to 1500 AD. The late Middle Ages followed the High Middle Ages and preceded the onset of the early modern period (and in much of Europe, the Renaissance).

Around 1350, centuries of prosperity and growth in Europe came to a halt. A series of famines and plagues, including the Great Famine of 1315–1317 and the Black Death, reduced the population to around half of what it had been before the calamities. Along with depopulation came social unrest and endemic warfare. France and England experienced serious peasant uprisings, such as the Jacquerie and the Peasants' Revolt, as well as over a century of intermittent conflict, the Hundred Years' War. To add to the many problems of the period, the unity of the Catholic Church was temporarily shattered by the Western Schism. Collectively, those events are sometimes called the crisis of the late Middle Ages.

The Latin Church (Latin: Ecclesia Latina) is the largest autonomous (sui iuris) particular church within the Catholic Church, whose members constitute the vast majority of the 1.3 billion Catholics. The Latin Church is one of 24 sui iuris churches in full communion with the pope; the other 23 are collectively referred to as the Eastern Catholic Churches, and they have approximately 18 million members combined.

The Latin Church is directly headed by the pope in his role as the bishop of Rome, whose cathedra as a bishop is located in the Archbasilica of Saint John Lateran in Rome, Italy. The Latin Church both developed within and strongly influenced Western culture; as such, it is sometimes called the Western Church (Latin: Ecclesia Occidentalis), which is reflected in one of the pope's traditional titles in some eras and contexts, the Patriarch of the West. It is also known as the Roman Church (Latin: Ecclesia Romana), the Latin Catholic Church, and in some contexts as the Roman Catholic Church (though this name can also refer to the Catholic Church as a whole).

Western civilization traces its roots back to Europe and the Mediterranean. It began in ancient Greece, transformed in ancient Rome, and evolved into medieval Western Christendom before experiencing such seminal developmental episodes as the development of Scholasticism, the Renaissance, the Reformation, the Scientific Revolution, the Enlightenment, the Industrial Revolution, and the development of liberal democracy. The civilizations of classical Greece and Rome are considered seminal periods in Western history. Major cultural contributions also came from the Christianized Germanic peoples, such as the Longobards, the Franks, the Goths, and the Burgundians. Charlemagne founded the Carolingian Empire and he is referred to as the "Father of Europe". Contributions also emerged from pagan peoples of pre-Christian Europe, such as the Celts and Germanic pagans as well as some significant religious contributions derived from Judaism and Hellenistic Judaism stemming back to Second Temple Judea, Galilee, and the early Jewish diaspora; and some other Middle Eastern influences. Western Christianity has played a prominent role in the shaping of Western civilization, which throughout most of its history, has been nearly equivalent to Christian culture. (There were Christians outside of the West, such as China, India, Russia, Byzantium and the Middle East). Western civilization has spread to produce the dominant cultures of modern Americas and Oceania, and has had immense global influence in recent centuries in many ways.

Following the 5th century Fall of Rome, Europe entered the Middle Ages, during which period the Catholic Church filled the power vacuum left in the West by the fall of the Western Roman Empire, while the Eastern Roman Empire (or Byzantine Empire) endured in the East for centuries, becoming a Hellenic Eastern contrast to the Latin West. By the 12th century, Western Europe was experiencing a flowering of art and learning, propelled by the construction of cathedrals, the establishment of medieval universities, and greater contact with the medieval Islamic world via Al-Andalus and Sicily, from where Arabic texts on science and philosophy were translated into Latin. Christian unity was shattered by the Reformation from the 16th century. A merchant class grew out of city states, initially in the Italian peninsula (see Italian city-states), and Europe experienced the Renaissance from the 14th to the 17th century, heralding an age of technological and artistic advance and ushering in the Age of Discovery which saw the rise of such global European empires as those of Portugal and Spain.

The Holy See (Latin: Sancta Sedes, lit. 'Holy Chair', Ecclesiastical Latin pronunciation: [ˈsaŋkta ˈsedes]; Italian: Santa Sede [ˈsanta ˈsɛːde]), also called the See of Rome, the Petrine See or the Apostolic See, is the central governing body of the Catholic Church and Vatican City. It encompasses the office of the pope as the bishop of the apostolic episcopal see of Rome, and serves as the spiritual and administrative authority of the worldwide Catholic Church and Vatican City. Under international law, the Holy See holds the status of a sovereign juridical entity.

According to Catholic tradition and historical records, the Holy See was founded in the first century by Saint Peter and Saint Paul. By virtue of the doctrines of Petrine and papal primacy, it is the focal point of full communion for Catholics around the world. The Holy See is headquartered in, operates from, and exercises "exclusive dominion" over Vatican City, an independent city-state enclaved in Rome, and of which the pope is the head of state.

Caput Mundi is a Latin phrase which literally means "Head of the world" whereas Roma Caput Mundi means "Rome capital of the world" and is one of the many nicknames given to the city of Rome throughout its history. The phrase is related to the enduring power of the city first as the capital of the Republic and the Empire, and later as the centre of the Catholic Church.

Although it is not known for sure when it was first used, Rome was already named in this way by the poet Ovid in 1st century BC. Along with "Eternal City" and the "City of Seven Hills", Caput Mundi remains as one of the most commonly used names to refer to the city of Rome.

The Papal Basilica of Saint Peter in the Vatican (Italian: Basilica Papale di San Pietro in Vaticano), or simply St. Peter's Basilica (Latin: Basilica Sancti Petri; Italian: Basilica di San Pietro [baˈziːlika di sam ˈpjɛːtro]), is a church of the Italian High Renaissance located in Vatican City, an independent microstate enclaved within the city of Rome, Italy. It was initially planned in the 15th century by Pope Nicholas V and then Pope Julius II to replace the ageing Old St. Peter's Basilica, which was built in the fourth century by Roman emperor Constantine the Great. Construction of the present basilica began on 18 April 1506 and was completed on 18 November 1626.

Designed principally by Donato Bramante, Michelangelo, and Carlo Maderno, with piazza and fittings by Gian Lorenzo Bernini, Saint Peter's is one of the most renowned works of Italian Renaissance architecture and is the largest church in the world by interior measure. While it is neither the mother church of the Catholic Church nor the cathedral of the Diocese of Rome (these equivalent titles being held by the Archbasilica of Saint John Lateran in Rome), Saint Peter's is regarded as one of the holiest Catholic shrines. It has been described as "holding a unique position in the Christian world", and as "the greatest of all churches of Christendom".

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 Spanish colonization of the Americas began in 1493 on the Caribbean island of Hispaniola (now Haiti and the Dominican Republic) after the initial 1492 voyage of Genoese mariner Christopher Columbus under license from Queen Isabella I of Castile. These overseas territories of the Spanish Empire were under the jurisdiction of Crown of Castile until the last territory was lost in 1898. Spaniards saw the dense populations of Indigenous peoples as an important economic resource and the territory claimed as potentially producing great wealth for individual Spaniards and the crown. Religion played an important role in the Spanish conquest and incorporation of indigenous peoples, bringing them into the Catholic Church peacefully or by force. The crown created civil and religious structures to administer the vast territory. Spanish men and women settled in greatest numbers where there were dense indigenous populations and the existence of valuable resources for extraction.

The Spanish Empire claimed jurisdiction over the New World in the Caribbean and North and South America, with the exception of Brazil, ceded to Portugal by the Treaty of Tordesillas. Other European powers, including England, France, and the Dutch Republic, took possession of territories initially claimed by Spain. Although the overseas territories under the jurisdiction of the Spanish crown are now commonly called "colonies" the term was not used until the second half of 18th century. The process of Spanish settlement, now called "colonization" and the "colonial era" are terms contested by scholars of Latin America and more generally.
