"Between the 1832 Great Reform Act and the outbreak of World War One in 1914, over 2,600 by-elections took place in Britain. They were triggered by the death, retirement or resignation of sitting MPs or by the appointment of cabinet ministers and were a regular feature of Victorian and Edwardian politics. They furnished political parties and their leaders with a crucial tool for gauging and mobilising public opinion. Yet despite the prominence of by-election contests in the historical records of this period, scholars have paid relatively little attention to them. As this book shows, these elections deserve to be taken as seriously today as people took them at the time. They provided important linkages between local and national politics, between the four parts of the United Kingdom and Westminster, and between foreign and domestic affairs. They are vital to understanding the evolving electioneering machineries, the varying language of electoral contests, the traction that particular issues had with a growing and frequently volatile electorate, and the fluctuating fortunes of the political parties. This book, consisting of original work by leading political historians, provides the first synoptic study of this important subject. It will be required reading for historians and students of modern British political history, as well as specialists in electoral history and politics."--Publisher's website.
