This book is a collection of the diary letters of Austen Chamberlain from 1916 to 1937. These letters provide a valuable insight into the political life of one of the leading Conservative politicians of the inter-war period, and constitute a detailed record of Conservative and national politics at this time. They provide particularly valuable personal accounts of key events such as the negotiations of the Irish Treaty in 1921, the troubles leading to the Carlton Club revolt of October 1922, the Locarno agreements of 1925, the leadership crisis of 1930–1, and the backbench campaign against the German threat in the 1930s. Chamberlain felt free to express his most candid feelings and emotions in the privacy of these diary letters and, as a result, they throw much valuable light upon arguably one of the most misjudged politicians of the age, and one who has certainly been overshadowed by his more famous father and half-brother.
