During the 10th and 11th centuries, the cathedral clergy became more definitely organised and were divided into two classes. One was that of a monastic establishment of some recognised order of monks, often the Benedictines, while the other class was that of a college of clergy, bound by no vows except those of their ordination, but governed by a code of statutes or canons: hence the name of "canon". In this way arose the distinction between the monastic and secular cathedral churches.
