The Inns of Chancery evolved in tandem with the Inns of Court. During the 12th and early 13th centuries the law was taught in the City of London, primarily by the clergy. But during the 13th century an event occurred which ended legal education by the Church. A papal bull in 1218 prohibited the clergy from practising in the secular, common law courts. As a result, law began to be practised and taught by laymen instead of by clerics. To protect their schools from competition, Henry II and Henry III issued proclamations prohibiting the teaching of the civil law within the City of London. These schools were based in hostels or "inns", which later took their name from the landlord of the inn in question.
