The "Canons and institutions drawn up and agreed upon by the General Assembly or Meeting of the heads of the Quakers from all parts of the kingdom" was produced following a meeting of leading Quakers in London in 1669. This had been drafted by George Fox, the name "Canons and Institutions" had been given to the publication by his opponents. It contained general advices and regulations, and was the basis of future books of discipline, although the name was formally disclaimed by Friends in 1675.
