Anselm of Canterbury (Aosta c. 1033 – Canterbury 21 April 1109), also called of Aosta for his birthplace, and of Bec for his home monastery, was a Benedictine monk, a philosopher, and a prelate of the Church who held the office of Archbishop of Canterbury from 1093 to 1109. Called the founder of scholasticism, he is famous as the originator of the ontological argument for the existence of God.

Born into the House of Candia, he entered the Benedictine order at the Abbey of Bec at the age of 27, where he became abbot in 1079. He became Archbishop of Canterbury under William II of England, and was exiled from England from 1097 to 1100, and again from 1105 to 1107 under Henry I of England as a result of the investiture controversy, the most significant conflict between Church and state in Medieval Europe.

Anselm was proclaimed a Doctor of the Church in 1720 by a Papal Bull of Pope Clement XI.

Anselm was born under the name "Anselmus Candiae Genavae" (Italian: Anselmo di Candia Ginevra, French: Anselme de Candie Genève) at or nearAosta in the Kingdom of Arles (currently the capital of the Aosta Valley region in Northern Italy) around 1033. His family was noble (they were related by blood to the ascendant House of Savoy) and owned considerable property. His parents were from a noble lineage and holders of fiefdoms within the Burgundian territories. His father, Gundulf de Candia, was by birth a Lombard of the House of Candia; he seems to have been harsh. His mother, Ermenberga of Geneva, was regarded as prudent and virtuous; she was related to Otto, Count of Savoy.

Canterbury (ⁱ/ˈkæntərbᵊri/ or /ˈkæntərbɛri/) is a historic English cathedral city, which lies at the heart of the City of Canterbury, a district of Kent in South East England. It lies on the River Stour.

Originally a Brythonic settlement, it was renamed Durovernum Cantiacorum by the Roman conquerors in the 1st century AD. After it became the chief Jutish settlement, it gained its English name Canterbury, itself derived from the Old English Cantwareburh ("Kent people's stronghold"). After the Kingdom of Kent's conversion to Christianity in 597, St Augustine founded an episcopal see in the city and became the first Archbishop of Canterbury, a position that now heads the Church of England and the worldwide Anglican Communion (though the modern-day Province of Canterbury covers the entire south of England). Thomas Becket's murder at Canterbury Cathedral in 1170 led to the cathedral becoming a place of pilgrimage for Christians worldwide. This pilgrimage provided the theme for Geoffrey Chaucer's 14th-century literary classic The Canterbury Tales. The literary heritage continued with the birth of the playwright Christopher Marlowe in the city in the 16th century.
