Kenneth O. Morgan 
Age of Lloyd George [PDF ebook] 
The Liberal Party and British Politics, 1890-1929

Originally published in 1971, this book traces the revival, triumph, division and decline of the British Liberal Party in the late 19th & 20th centuries. It does so by focusing on the career of David Lloyd George, itself the decisive agent for change in this period. The first part of the book is an extended critical essay; the second part consists of primary documentary material which is intimately linked to the commentary in the first section. The major phases of the period are covered: The tension between the Old Liberalism and the New; the challenges confronting the Liberal government of 1905-15; the impact of world war and Lloyd George’s wartime premiership; the Lloyd George coalition in 1918-22 and the reasons for its downfall; and the slow decline of the Liberals between 1922 and 1929.
