Pavil Gavrilovich, later Sir Paul, Vinogradoff [1854-1925] is well known in Russia principally as a historian and abroad as a legal historian and comparative lawyer. Few in either Russia or abroad are aware that Vinogradoff also wrote on public international law. This volume collects four of his most important contributions to this field: The Legal and Political Aspects of the League of Nations (1918), The Reality of the League of Nations (c. 1919), The Covenant of the League: Great and Small Powers (1919) and History of the Law of Nations, a series of six lectures delivered at the University of Leiden in 1921.
