Six lectures delivered to an audience at the University of Sussex, Brighton by Hugh Trevor-Roper, Regius Professor of Modern History in the University of Oxford.

Yet within a few years one obscure corner of Europe would revive the vitality of the whole continent-a revival that led to four hundred years of world domination.
