During the Middle Ages sheep farming for the wool trade came to dominate the economy of Exmoor. The wool was spun into thread on isolated farms and collected by merchants to be woven, fulled, dyed and finished in thriving towns such as Dunster. The land started to be enclosed and from the 17th century onwards larger estates developed, leading to establishment of areas of large regular shaped fields. During this period a Royal Forest and hunting ground was established, administered by the Warden. The Royal Forest was sold off in 1818.
