A requirement for banns of marriage was introduced to England and Wales by the Church in 1215. This required a public announcement of a forthcoming marriage, in the couple's parish church, for three Sundays prior to the wedding and gave an opportunity for any objections to the marriage to be voiced (for example, that one of the parties was already married or that the couple was related within a prohibited degree), but a failure to call banns did not affect the validity of the marriage.
