Merton Priory was an English Augustinian priory founded in 1114 by Gilbert Norman, Sheriff of Surrey under King Henry I (1100–1135). It was situated within the manor of Merton in the county of Surrey, in what is today the Colliers Wood area in the London Borough of Merton.

Edmund of Abingdon was an English-born prelate who served as Archbishop of Canterbury. He became a respected lecturer in mathematics, dialectics and theology at the Universities of Paris and Oxford, promoting the study of Aristotle. Having already an unsought reputation as an ascetic, he was ordained a priest, took a doctorate in divinity and soon became known not only for his lectures on theology but as a popular preacher, spending long years travelling within England, and engaging in 1227 preaching the Sixth Crusade. Obliged to accept an appointment as Archbishop of Canterbury by Pope Gregory IX, he combined a gentle personal temperament with a strong public stature and severity towards King Henry III in defence of Magna Carta and in general of good civil and Church government and justice. He also worked for strict observance in monastic life and negotiated peace with Llywelyn the Great. His policies earned him hostility and jealousy from the king, and opposition from several monasteries and from the clergy of Canterbury Cathedral. He died in France at the beginning of a journey to Rome in 1240. He was canonised in 1246.
