Archbishop of Canterbury in the context of "Anglican Communion"

Magna Carta (Medieval Latin for "Great Charter"), sometimes spelled Magna Charta, is a royal charter of rights sealed by King John of England at Runnymede, near Windsor, on 15 June 1215. First drafted by the Archbishop of Canterbury, Cardinal Stephen Langton, to make peace between the unpopular king and a group of rebel barons who demanded that the King confirm the Charter of Liberties, it promised the protection of church rights, protection for the barons from illegal imprisonment, access to swift and impartial justice, and limitations on feudal payments to the Crown, to be implemented through a council of 25 barons. Neither side stood by their commitments, and the charter was annulled by Pope Innocent III, leading to the First Barons' War.

After John's death, the regency government of his young son, Henry III, reissued the document in 1216, stripped of some of its more radical content, in an unsuccessful bid to build political support for their cause. At the end of the war in 1217, it formed part of the peace treaty agreed at Lambeth, where the document acquired the name "Magna Carta", to distinguish it from the smaller Charter of the Forest, which was issued at the same time. Short of funds, Henry reissued the charter again in 1225 in exchange for a grant of new taxes. His son, Edward I, repeated the exercise in 1297, this time confirming it as part of England's statute law. However, Magna Carta was not unique; other legal documents of its time, both in England and beyond, made broadly similar statements of rights and limitations on the powers of the Crown. The charter became part of English political life and was typically renewed by each monarch in turn. As time went by and the fledgling Parliament of England passed new laws, it lost some of its practical significance.

Christian tradition is a collection of traditions consisting of practices or beliefs associated with Christianity. Many churches have traditional practices, such as particular patterns of worship or rites, that developed over time. Deviations from such patterns are sometimes considered unacceptable by followers, or are regarded as heretical. There are certain Christian traditions that are practiced throughout the liturgical year, such as praying a daily devotional during Advent, erecting a nativity scene during Christmastide, chalking the door on Epiphany Day, fasting during Lent, waving palms on Palm Sunday, eating easter eggs during Eastertide, and decorating the church in red on Pentecost.

Tradition also includes historic teaching of the recognized church authorities, such as Church Councils and ecclesiastical officials (e.g., the Pope, Patriarch of Constantinople, Archbishop of Canterbury, etc.), and includes the teaching of significant individuals like the Church Fathers, the Protestant Reformers, and the founders of denominations. Many creeds, confessions of faith, and catechisms generated by these bodies are also part of the traditions of various bodies.

Anglicanism, also known as Episcopalianism in some countries, is a Western Christian tradition which developed from the practices, liturgy, and identity of the Church of England following the English Reformation, in the context of the Protestant Reformation in Europe. It is one of the largest branches of Christianity, with around 110 million adherents within the Anglican Communion, and more than 400,000 outside of the Anglican Communion, worldwide as of 2025.

Adherents of Anglicanism are called Anglicans; they are also called Episcopalians in some countries. Most are members of national or regional ecclesiastical provinces of the international Anglican Communion, one of the largest Christian bodies in the world, and the world's third-largest Christian communion. The provinces within the Anglican Communion have historically been in full communion with the See of Canterbury and thus with the archbishop of Canterbury, whom the communion refers to as its primus inter pares (Latin, 'first among equals'). The archbishop calls the decennial Lambeth Conference, chairs the meeting of primates, and is the president of the Anglican Consultative Council. Some churches that are not part of the Anglican Communion or recognised by it also call themselves Anglican, including those that are within the Continuing Anglican movement and Anglican realignment.

Edward the Martyr (c. 962 – 18 March 978) was King of the English from 8 July 975 until he was killed in 978. He was the eldest son of King Edgar (r. 959–975). On Edgar's death, the succession to the throne was contested between Edward's supporters and those of his younger half-brother, the future King Æthelred the Unready. As they were both children, it is unlikely that they played an active role in the dispute, which was probably between rival family alliances. Edward's principal supporters were Dunstan, Archbishop of Canterbury, and Æthelwine, Ealdorman of East Anglia, while Æthelred was backed by his mother, Queen Ælfthryth and her friend Æthelwold, Bishop of Winchester. The dispute was quickly settled. Edward was chosen as king and Æthelred received the lands traditionally allocated to the king's eldest son in compensation.

Edgar had been a strong and overbearing king and a supporter of the monastic reform movement. He had forced the lay nobility and secular clergy to surrender land and sell it at low prices to the monasteries. Æthelwold had been the most active and ruthless in seizing land for his monasteries with Edgar's assistance. The nobles took advantage of Edgar's death to get their lands back, mainly by legal actions but sometimes by force. The leading magnates were split into two factions, the supporters of Ælfhere, Ealdorman of Mercia, and Æthelwine, who both seized some monastic lands which they believed belonged to them, but also estates claimed by their rivals. The disputes never led to warfare.

Anselm of Canterbury OSB (/ˈænsɛlm/; 1033/4–1109), also known as Anselm of Aosta (French: Anselme d'Aoste, Italian: Anselmo d'Aosta) after his birthplace and Anselm of Bec (French: Anselme du Bec) after his monastery, was an Italian Benedictine monk, abbot, philosopher, and theologian of the Catholic Church, who served as Archbishop of Canterbury from 1093 to 1109.

As Archbishop of Canterbury, he defended the church's interests in England amid the Investiture Controversy. For his resistance to the English kings William II and Henry I, he was exiled twice: once from 1097 to 1100 and then from 1105 to 1107. While in exile, he helped guide the Greek Catholic bishops of southern Italy to adopt Roman Rites at the Council of Bari. He worked for the primacy of Canterbury over the Archbishop of York and over the bishops of Wales, and at his death he appeared to have been successful; however, Pope Paschal II later reversed the papal decisions on the matter and restored York's earlier status.

Rowan Douglas Williams, Baron Williams of Oystermouth (born 14 June 1950), is a Welsh Anglican bishop, theologian and poet, who served as the 104th Archbishop of Canterbury from 2002 to 2012. Previously the Bishop of Monmouth and Archbishop of Wales, Williams was the first Archbishop of Canterbury in modern times not to be appointed from within the Church of England.

Williams's primacy was marked by speculation that the Anglican Communion (in which the Archbishop of Canterbury is the leading figure) was fragmenting over disagreements on contemporary issues such as homosexuality and the ordination of women. Williams worked to keep all sides in dialogue. Notable events during his time as Archbishop of Canterbury include the rejection by a majority of dioceses of his proposed Anglican Covenant and, in the final general synod of his tenure, his unsuccessful attempt to secure a sufficient majority for a measure to allow the appointment of women as bishops in the Church of England.
