North west England has largely been neglected in studies of medieval landscapes in favour of the Midlands and East Anglia although it has much to offer. Described here as a `frontier landscape' encompassing the modern regions of Lancashire, Cheshire, Merseyside and Greater Manchester, the author discusses changes to the medieval landscape and why these occurred. He outlines and characterises the major period of expansion and economic boom that took place in the north west from 1086 to 1349 and asks why political and military matters seen to have had such an important role in landscape change. Issues of perceived marginality are also discussed as Higham looks in turn at the local population and their environment, land use and agrarian practices, woodland, forest and pasture, buildings, farms and estates, markets and fairs and the Church and the landscape. A great addition to the series.
