Augustine of Canterbury in the context of "Prior (ecclesiastical)"

The Romano-British culture arose in Britain under the Roman Empire following the Roman conquest in AD 43 and the creation of the province of Britannia. It arose as a fusion of the imported Roman culture with that of the indigenous Britons, a people of Celtic language and custom.

Scholars such as Christopher Snyder believe that during the 5th and 6th centuries – approximately from 410 when the Roman legions withdrew, to 597 when St Augustine of Canterbury arrived – southern Britain preserved an active sub-Roman culture that survived the attacks from the Anglo-Saxons and even used a vernacular Latin when writing.

The architecture of the United Kingdom, or British architecture, consists of a combination of architectural styles, dating as far back to Roman architecture, to the present day 21st century contemporary. England has seen the most influential developments, though Ireland, Scotland, and Wales have each fostered unique styles and played leading roles in the international history of architecture. Although there are prehistoric and classical structures in the United Kingdom, British architectural history effectively begins with the first Anglo-Saxon Christian churches, built soon after Augustine of Canterbury arrived in Great Britain in 597. Norman architecture was built on a vast scale throughout Great Britain and Ireland from the 11th century onwards in the form of castles and churches to help impose Norman authority upon their dominions. English Gothic architecture, which flourished between 1180 until around 1520, was initially imported from France, but quickly developed its own unique qualities.

Throughout the United Kingdom, secular medieval architecture has left a legacy of large stone castles, with a concentration being found lining both sides of the Anglo-Scottish border, dating from the Wars of Scottish Independence of the 14th century. The invention of gunpowder and cannons made castles redundant, and the English Renaissance that followed facilitated development of new artistic styles for domestic architecture: Tudor style, English Baroque, Queen Anne Style, and Palladian. Georgian, Scots Baronial and Neoclassical architecture advanced after the Scottish Enlightenment, and since the 1930s various modernist forms appeared, though traditionalist resistance movements continue with support from Charles, Prince of Wales.

The Church of England (C of E) is the established Christian church in England and the Crown Dependencies. It was the initial church of the Anglican tradition. The Church traces its history to the Christian hierarchy recorded as existing in the Roman province of Britain by the 3rd century and to the 6th-century Gregorian mission to Kent led by Augustine of Canterbury. Its members are called Anglicans.

In 1534, the Church of England renounced the authority of the Papacy under the direction of King Henry VIII pursuant to laws passed by the Parliament, beginning the English Reformation. The guiding theologian that shaped Anglican doctrine was the reforming Archbishop Thomas Cranmer, who developed the Church of England's liturgical text, the Book of Common Prayer. Papal authority was briefly restored under Mary I, before her successor Elizabeth I renewed the breach. The Elizabethan Settlement (implemented 1559–1563) concluded the English Reformation, charting a course for the English church to describe itself as a via media between two branches of Protestantism—Lutheranism and Calvinism—and later, a denomination that is both Reformed and Catholic.

The Catholic Church in England and Wales (Latin: Ecclesia Catholica in Anglia et Cambria; Welsh: Yr Eglwys Gatholig yng Nghymru a Lloegr) is part of the worldwide Catholic Church in full communion with the Holy See. Its origins date from the 6th century, when Pope Gregory I through a Roman missionary and Benedictine monk, Augustine, later Augustine of Canterbury, intensified the evangelization of the Kingdom of Kent, linking it to the Holy See in 597 AD.

This unbroken communion with the Holy See lasted until King Henry VIII ended it in 1534. Communion with Rome was restored by Queen Mary I in 1555 following the Second Statute of Repeal and eventually finally broken by Elizabeth I's 1559 Religious Settlement, which made "no significant concessions to Catholic opinion represented by the church hierarchy and much of the nobility."

The archbishop of Canterbury is the senior bishop and a principal leader of the Church of England, the ceremonial head of the worldwide Anglican Communion, the bishop of the diocese of Canterbury and metropolitan of the Province of Canterbury. By virtue of their office the archbishop is also a Lord Spiritual, one of the 26 Church of England bishops who sit in the House of Lords of the Parliament of the United Kingdom. The office has been vacant since 7 January 2025 following the resignation of Justin Welby, the 105th archbishop. Dame Sarah Mullally, currently the bishop of London, will become archbishop on 28 January 2026; she will be the first woman to hold the office.

The first archbishop was Augustine of Canterbury, the "Apostle to the English", who was sent to England by Pope Gregory the Great and arrived in 597. From Augustine until William Warham the archbishops of Canterbury were in full communion with the Catholic Church. During the English Reformation, King Henry VIII broke communion with Rome and proclaimed himself the head of the Church of England. Thomas Cranmer, appointed in 1533, became the first Protestant archbishop of Canterbury and would become one of the most important figures in the development of Anglicanism.

Pope Gregory I (Latin: Gregorius I; Gregorio I; c. 540 – 12 March 604), commonly known as Saint Gregory the Great (Latin: Sanctus Gregorius Magnus; Italian: San Gregorio Magno), was the 64th Bishop of Rome from 3 September 590 until his death on 12 March 604. He is known for instituting the first recorded large-scale mission from Rome, the Gregorian mission, to convert the then largely pagan Anglo-Saxons to Christianity. Gregory is also well known for his writings, which were more prolific than those of any of the previous popes. The epithet Saint Gregory the Dialogist has been attached to him in Eastern Christianity because of his Dialogues. English translations of Eastern texts sometimes list him as Gregory "Dialogos" from the Greek διάλογος (dialogos, conversation), or the Anglo-Latinate equivalent "Dialogus". He is the second of the three Popes listed in the Annuario Pontificio with the title "the Great", alongside Popes Leo I and Nicholas I.

A Roman senator's son, and himself the prefect of Rome at 30, Gregory lived in a monastery that he established on his family estate before becoming a papal ambassador and then pope. Before becoming Pope, he challenged the theological views of Patriarch Eutychius of Constantinople before the emperor Tiberius II. Although he was the first pope from a monastic background, his prior political experiences may have helped him to be a talented administrator. During his papacy, his administration greatly surpassed that of the emperors Maurice and Theodosius in improving the welfare of the people of Rome. Gregory regained papal authority in Spain and France and sent missionaries to England, including Augustine of Canterbury and Paulinus of York. The realignment of barbarian allegiance to Rome from their Arian Christian alliances shaped medieval Europe. Gregory saw Franks, Lombards, and Visigoths align with Rome in religion. He also combated the Donatist heresy, popular particularly in North Africa at the time.
