It is difficult to give a list of books illustrating foreign policy in general. The lists given in other chapters sufficiently illustrate the various problems with which foreign policy to-day has to deal.
The diplomacy of a century ago is well illustrated by the Diaries and Correspondence of the Earl of Malmesbury. 4 vols. 1844. (Out of print.) For the diplomacy of the middle of the nineteenth century, when the present national forces of Europe were being created, the following biographies are useful:
Life of Lord Stratford de Redcliffe, by Lane-Poole. 2 vols. 1888.
Life of Lord Granville, by Lord Fitzmaurice. 2 vols. 1905.
Life of Lord Clarendon, by Sir Herbert Maxwell. 2 vols. 1913.
Life of Lord Lyons, by Lord Newton. 2 vols. 1898.
Life of Cavour, by Roscoe Thayer. 2 vols. 1911.
There are many studies of the diplomatic problems of the present day, but as they deal with history in the making they are to be read for the general survey they give of forces at work rather than as authoritative statements. A very comprehensive survey of all the complexities of international politics will be found in Fullerton’s Problems of Power (1913). 7s. 6d. net.
The actual workings of diplomacy may best be seen in the “White Books” of diplomatic correspondence, periodically published by the Foreign Office, such, for instance, as the successive volumes of Correspondence Respecting the Affairs of Persia. Perhaps the best idea of the actual labour of foreign relations can be gained by consulting such compilations as Hertslet’s Commercial Treaties—23 vols. 1827-1905—which are a record of work actually completed.
