The fifty years from the last decade of the eighteenth century saw great changes in Britain. Significant technological and economic change, not to mention wars, affected great swathes of the population and profoundly changed many aspects of life. In this book Fabian Hiscock considers this dramatic upheaval as it played out in western Hertfordshire, focusing in particular on just one of the many innovations of the time: the Grand Junction Canal, created to connect the Midlands with London. Having described the complex process of creating the Canal itself, the author turns to how western Hertfordshire experienced, and responded to, the new trade route that now traversed its fields and settlements. In the area's towns and villages - particularly Rickmansworth, Watford, Hemel Hempstead, Berkhamsted and Tring - the Canal made an impact, but to what extent did it live up to the promises made by its promoters? And what were the impacts on trade and transport, on work and home life? Did it create jobs and wealth for local people? Or did it simply pass through, leaving those living on either side relatively unaffected? Whether and in what way western Hertfordshire changed as a result of the Grand Junction Canal is the focus of this work. 1841 is the chosen end date for the study period because of the coincidence of the Census undertaken that year, which sheds some light on the industrial make-up of the area, the tithe awards made between 1838 and 1844, allowing study of the Canal's effect on land ownership and usage across the area, and the start of the London and Birmingham Railway's real economic effect. In combining canal history with a detailed social and economic study of a part of the county that is not much written about, Fabian Hiscock has written a superbly researched and wide-reaching book that will be of interest to a broad range of readers.
