The Archbishop of Canterbury is the senior bishop and principal leader of the Church of England, the symbolic head of the worldwide Anglican Communion and the diocesan bishop of the Diocese of Canterbury. The current archbishop is Justin Welby. His enthronement took place at Canterbury Cathedral on 21 March 2013. Welby is the 105th in a line which goes back more than 1400 years to Augustine of Canterbury, the "Apostle to the English", sent from Rome in the year 597. Welby succeeded Rowan Williams. 

From the time of St Augustine of Canterbury in the 6th century, until Archbishop Reginald Pole in the 16th century, the Archbishops of Canterbury were in full communion with the See of Rome and they usually received the pallium. During the English Reformation, based upon King Henry VIII's divorce from Catherine of Aragon, the Church of England broke away from the authority of the Pope and the Roman Catholic Church. 

In the Middle Ages there was considerable variation in the methods of nomination of the Archbishop of Canterbury and other bishops. At various times the choice was made by the canons of Canterbury Cathedral, the Pope, or the King of England. Since the English Reformation, the Church of England has been more explicitly a state church and the choice is legally that of the Crown; today it is made by the Queen on the advice of the Prime Minister, who receives a shortlist of two names from an "ad hoc" committee called the Crown Nominations Commission.
