In 1906 Krabbe published in German his seminal book Die Lehre der Rechtssouveränität ("The theory of the sovereignty of law"), which has been one of the most controversial works in Dutch jurisprudence together with his following book De moderne staatsidee ("The Modern Idea of the State"), published in 1915 and soon translated into German, French and English. The English translation of the latter book was undertaken by two renowned American academics, the political philosopher Georg H. Sabine and the professor of political science ; their eighty-page translators' introduction attests to Krabbe's international standing, his topicality at the time and the salience of his contribution to the international liberal values during the interwar period often associated with Wilsonianism.
