RomanRomaRome, Italy
The Bishops of Rome were also seen (and still are seen by Catholics) as the successors of Peter, who is considered the first Bishop of Rome. The city thus became of increasing importance as the centre of the Catholic Church. After the fall of the Western Roman Empire in 476 AD, Rome was first under the control of Odoacer and then became part of the Ostrogothic Kingdom before returning to East Roman control after the Gothic War, which devastated the city.

Theodosius I

TheodosiusTheodosius the GreatTheodosian
As his heir in the Eastern Roman Empire he left Arcadius, who was about eighteen years old, and in the Western Roman Empire Honorius, who was ten. Neither ever showed any sign of fitness to rule, and their reigns were marked by a series of disasters. As their guardians Theodosius left Stilicho, who ruled in the name of Honorius in the Western Empire, and Flavius Rufinus who was the actual power behind the throne in the East. Several historians mark the day of Theodosius' death as the beginning of the Middle Ages.

Justinian I

JustinianEmperor JustinianJustinian the Great
Having thus secured his eastern frontier, Justinian turned his attention to the West, where Germanic kingdoms had been established in the territories of the former Western Roman Empire. The first of the western kingdoms Justinian attacked was that of the Vandals in North Africa. King Hilderic, who had maintained good relations with Justinian and the North African Catholic clergy, had been overthrown by his cousin Gelimer in 530 A.D. Imprisoned, the deposed king appealed to Justinian. In 533, Belisarius sailed to Africa with a fleet of 92 dromons, escorting 500 transports carrying an army of about 15,000 men, as well as a number of barbarian troops.

Byzantine Empire

ByzantineByzantinesEastern Roman Empire
Urban saw Alexios's request as a dual opportunity to cement Western Europe and reunite the Eastern Orthodox Church with the Roman Catholic Church under his rule. On 27 November 1095, Pope Urban II called together the Council of Clermont, and urged all those present to take up arms under the sign of the Cross and launch an armed pilgrimage to recover Jerusalem and the East from the Muslims. The response in Western Europe was overwhelming. Alexios had anticipated help in the form of mercenary forces from the West, but he was totally unprepared for the immense and undisciplined force that soon arrived in Byzantine territory.

Edict of Nantes

Revocation of the Edict of NantesEdict of Nantes 1598
The Edict succeeded in restoring peace and internal unity to France, though it pleased neither party: Catholics rejected the apparent recognition of Protestantism as a permanent element in French society and still hoped to enforce religious uniformity, while Protestants aspired to parity with Catholics. "Toleration in France was a royal notion, and the religious settlement was dependent upon the continued support of the crown." Re-establishing royal authority in France required internal peace, based on limited toleration enforced by the crown. Since royal troops could not be everywhere, Huguenots needed to be granted strictly circumscribed possibilities of self-defense.

Same-sex marriage

Opponents of same-sex marriage, who want marriage to be restricted to heterosexuals, such as The Church of Jesus Christ of Latter-day Saints, the Catholic Church, and the Southern Baptist Convention, use the term traditional marriage to mean opposite-sex marriage.


Teresina, Fortaleza, and Florianópolis were the most Roman Catholic in the country. Greater Rio de Janeiro, not including the city proper, is the most irreligious and least Roman Catholic Brazilian periphery, while Greater Porto Alegre and Greater Fortaleza are on the opposite sides of the lists, respectively. According to IBGE (Brazilian Institute of Geography and Statistics) urban areas already concentrate 84.35% of the population, while the Southeast region remains the most populated one, with over 80 million inhabitants.

Papal States

It also included the small enclaves of Benevento and Pontecorvo in southern Italy and the larger Comtat Venaissin around Avignon in southern France. The French Revolution affected the temporal territories of the Papacy as well as the Roman Church in general. In 1791 Revolutionary France annexed the Comtat Venaissin and Avignon. Later, with the French invasion of Italy in 1796, the Legations (the Papal States' northern territories) were seized and became part of the Cisalpine Republic. Two years later, French forces invaded the remaining area of the Papal States and General Louis-Alexandre Berthier declared a Roman Republic (February 1798).


After the barbarians overran the Western Roman Empire, Constantinople became the indisputable capital city of the Roman Empire. Emperors were no longer peripatetic between various court capitals and palaces. They remained in their palace in the Great City and sent generals to command their armies. The wealth of the eastern Mediterranean and western Asia flowed into Constantinople. The emperor Justinian I (527–565) was known for his successes in war, for his legal reforms and for his public works. It was from Constantinople that his expedition for the reconquest of the former Diocese of Africa set sail on or about 21 June 533.


Gaul (Gallia; Γαλατία, Galatía) was a region of Western Europe during the Iron Age that was inhabited by Celtic tribes, encompassing present day France, Luxembourg, Belgium, most of Switzerland, parts of Northern Italy, as well as the parts of the Netherlands and Germany on the west bank of the Rhine. It covered an area of 494,000 km2. According to the testimony of Julius Caesar, Gaul was divided into three parts: Gallia Celtica, Belgica, and Aquitania.


LyonLugdunum (Lyon)Lyons
Though the Western Empire persisted another century and a half, the border regions extending along the Rhine River in Germany to the Danube River in Dacia became far more important from a military and strategic standpoint. Cities like Augusta Treverorum (Trier) eclipsed Lugdunum in importance. The status of the western provinces declined further when Constantine made Byzantium (later named Constantinople after his death), the capital of the Eastern part of the Empire. As the Western Empire disintegrated in the 5th century, Lugdunum became the principal city of the Burgundian kingdom. History of Lyon. Abascantus. Dio Cassius. Roman History. XLVI, 50.

Switzerland has no official state religion, though most of the cantons (except Geneva and Neuchâtel) recognise official churches, which are either the Roman Catholic Church or the Swiss Reformed Church. These churches, and in some cantons also the Old Catholic Church and Jewish congregations, are financed by official taxation of adherents. Christianity is the predominant religion of Switzerland (about 68% of resident population in 2016 and 75% of Swiss citizens ), divided between the Roman Catholic Church (37.2% of the population), the Swiss Reformed Church (25.0%), further Protestant churches (2.2%) and other Christian denominations (1.3%).

Vatican City

Vatican🇻🇦the Vatican
The Holy See dates back to early Christianity, and is the primate episcopal see of the Catholic Church, with 1.3 billion Catholics around the world distributed in the Latin Church and 23 Eastern Catholic Churches. The independent Vatican City-state, on the other hand, came into existence in 11 February 1929 by the Lateran Treaty between the Holy See and 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. Within the Vatican City are religious and cultural sites such as St. Peter's Basilica, the Sistine Chapel and the Vatican Museums.

East–West Schism

Great SchismschismGreat Schism of 1054
There have been periodic conflicts between the Orthodox and Eastern Catholics in Ukraine and Belarus, then under Polish rule, and later also in Transylvania (see the Romanian Greek Catholic Church United with Rome). Pressure and government-sponsored reprisals were used against Eastern Catholic Churches such as the Ukrainian Greek Catholic Church in the Russian Empire and later in the USSR. Since the late 1980s, the Moscow Patriarchate (the Russian Orthodox Church) has criticised the methods of restoration of the ″uniate″ church structures in Ukraine as well as what it called Catholic proselytism in Russia.

Napoleonic Wars

Napoleonicwar with FranceNapoleonic War
The Napoleonic Wars brought radical changes to Europe, but the reactionary forces returned to power and tried to reverse some of them by restoring the Bourbon house on the French throne. Napoleon had succeeded in bringing most of Western Europe under one rule. In most European countries, subjugation in the French Empire brought with it many liberal features of the French Revolution including democracy, due process in courts, abolition of serfdom, reduction of the power of the Catholic Church, and a demand for constitutional limits on monarchs.


cathedralscathedral churchproto-cathedral
Prior to the Reformation all cathedrals of Western Europe were of the Roman Catholic Church. In England, much of the structure of the monastic and cathedral system was reconstituted during the English Reformation. Although the cathedrals were retained by the now independent and established Church of England, the monastic cathedral chapters were dissolved by King Henry VIII and, with the exceptions of Bath and Coventry, were refounded by him as chapters of canons with a dean as the head and other clergy as minor canons.
