All Diplomatic Correspondence and Secret Agreements of the Long Nineteenth Century, 1815 to 1913

This group gathers the diplomatic correspondence and secret agreements of the long nineteenth century, 1815 to 1913. These are the diplomatic letters, telegrams, notes, memoranda and secret agreements through which governments dealt with one another, often unseen by the public at the time. A document belongs here when its cited article gives a date inside this span for the document's own signing, adoption, issue or composition. It excludes documents dated earlier or later, which sit in the neighboring period groups of the same kind. The long nineteenth century from 1815 to 1913 covers the settlement after Napoleon, industrial growth, liberal revolutions and the rise of European and American empires.
