<p>This dissertation consists of an examination of the Liberal Unionist party over the entire period of its existence, from 1886to1912, and demonstrates the importance of the party to a complete understanding of British political history in the late-Victorian and Edwardian periods. The Liberal Unionist party retained a significant degree of independence from other parties for far longer than historians have generally assumed. In particular, the relationship between the Liberal Unionist party and the Conservative party, with whom they co-operated in an electoral alliance from 1886 and participated in a coalition government from 1895 to 1905, continued to be fraught with tension and conflicts over parliamentary representation and ideology until the last years of the party's existence. Conversely, many Liberal Unionists retained ties of sentiment and ideology with the Liberal parties for many years after the Home Rule division of 1886. In the course of demonstrating the continued independence of the Liberal Unionist party, this dissertation examines the central and local party organization, the operation of the electoral alliance between the Liberal Unionists and Conservatives, and the construction and nature of Liberal Unionist identity. An important component of this dissertation is the identification of every Liberal Unionist candidate and M.P. based on a variety of primary sources (see Appendixes C and D), which allows for a more detailed and accurate discussion of the history of the party than previously had been possible.</p> / Thesis / Doctor of Philosophy (PhD)
