British documents on the origins of the War (1898-1914)
This series, in eleven volumes edited by G. P. Gooch and Harold Temperley, presents the key documents in British diplomatic history from the abandonment of the policy of 'splendid isolation' in 1898 to the declaration of war against Germany on 4 August 1914.
The decision to publish the British Documents on the Origins of the War was announced in a letter of the 28th November, 1924 by Foreign Secretary Austen Chamberlain. A collection of the documents between the assassination of Archduke Franz Ferdinand and the declaration of war had already been made by J. W. Headlam-Morley, the Historical Adviser of the Foreign Office, and this became the first volume to be published, in 1926, as Volume XI of the series. Volumes I-X were subsequently published between 1927-1938.
In addition to the official records of the Foreign Office, selected minutes and private letters were also included. Documents which had previously been published elsewhere were usually excluded.
