A grant of the common land to the freeholders and other tenants, made by deed in 1360 by John de Mowbray, Lord of the Manor, gave privileges and freedoms over the use of common land, reed gathering, rights over fish and fowl and such wildlife as could be taken by the commoners for food. The deed caused repercussions in the reign of King Charles I (1625-1649) when Vermuyden was granted the task of draining the Isle and he and his Dutch partners came under regular attack in their stockade at Sandtoft. The draining of the land saw the ancient rights of the commoners encroached upon: as the land dried up they lost their supply of wildfowl for food, foraging rights and employment as mere men, swanniers, and ferry operators in addition to their grazing rights. A whole way of life that had seen annual otter hunts on the Trent, not to mention abundant salmon, was lost along with many livelihoods. The resentment felt by the Isle of Axholme towards the king doubtless explains their siding with Parliament in the English Civil War (1642-1651). Nevertheless, Vermuyden’s work, an outstanding piece of irrigation engineering, turned thousands of acres of marsh and bog, which had been impassable except in high summer or hard frost, into the rich arable farmland that the Isle benefits from today. Extensive drainage continued, which, together with periodic warping (intentional flooding to deposit silt and enrich the land), has made this an exceptionally fertile area. The Isle of Axholme was originally the eight parishes of Althorpe, Belton, Crowle, Epworth, Haxey, Luddington, Owston and Wroot.
