Foundations of British Foreign Policy [PDF ebook] 
1792 – 1902

First published in 1938, this volume represents a selection of unpublished and published documents dealing with foreign affairs, from the rise of the Younger Pitt to the death of Salisbury. It contains both official papers and private letters; speeches and other public statements of policy. The Editors have had access to a large number of unpublished materials, public and private, so that many of the documents that they have chosen are new and reveal a striking continuity of ideas in British diplomacy, despite opposed parties and even opposing policies.
