The guernsey is the mainstay of Guernsey's knitting industry which can be dated back to the late 15th century when a royal grant was obtained to import wool from England and re-export knitted goods to Normandy and Spain. Peter Heylin described the manufacture and export of "waste-cotes" during the reign of Charles I. The first use of the name "guernsey" outside of the island is in the 1851 "Oxford Dictionary", but the garment was in use in the bailiwick before that.
