A learned, definitive history of international law, from the time of the early Greeks to the outbreak of World War II. The author correlates legal history with political developments, which broadens its scope of interest. He traces the seeds of the law of nations in the Greek and Roman civilizations and the great strides made in legal history through the Middle Ages up to the Congress of Vienna which opened the modern era of international law. Prof. Nussbaum devotes a chapter to each century and his method is to precede each section with a review of political developments of the era and then to go on with the doctrinal and literary progress and short biographies of the great legal men of the times:- Thomas Aquinas, Francisco Vitoria, Francisco Suarez, Gentili, Grotius, Hobbs, Bynkershock, Wolff, DeVattel, Moser. Inclusive, concise bibliography for the student.
