Edward III brought over Flemish weavers to develop the Wealden cloth industry using wool from Romney Marsh; Cranbrook became the centre of this as it had local supplies of fuller's earth and plenty of streams that could be dammed to drive the fulling mills. Iron-making was carried on at Bedgebury on the River Teise, an industry which dates back to Roman times. The tributaries of the River Beult around Cranbrook powered 17 watermills at one time. In 1290 the town received a charter from Archbishop Peckham, allowing it to hold a market in the High Street.
