Leeds handled one sixth of England's export trade in 1770. Growth, initially in textiles, was accelerated by the creation of the Aire and Calder Navigation in 1699 (with major additional works in the 18th century) and the Leeds and Liverpool Canal in 1816. In the late Georgian era, William Lupton was one of a number of central Leeds landowners, some of whom, like him, were also textile manufacturers. At the time of his death in 1828, Lupton occupied the enclosed fields of the manor of Leeds, his estate including a mill, reservoir, substantial house and outbuildings.
