Abstract
Arnold J. Toynbee was not only a controversial historian, but also a beguiling internationalist. This article analyses Toynbee as an observer of international politics. In particular, it examines both his understanding of contemporary foreign politics and his constant search of a stable world order. From the idealism of his youth to the utopianism of religious origin that marked his final years, passing through his partial and temporary disenchantment with regard to his youthful expectations, this essay will follow Toynbee’s path in the study of the international affairs of the Twentieth century.
