"The twenty years' crisis, 1919-1939: an introduction to the study of International Relations" (2001). Brasília: Publisher Brasília University: 305 pp. ISBN: 85-230-0635-4

Abstract

The science of International Relations originated in the nineteenth century, before the two great world wars. The main object of this new science was to prevent ills in the international body politic and to avoid the causes and pressures leading to a new war. The fervent desire to prevent war determined the first observations of the discipline’s study, as well as its direction.
