The Roma had probably already been living in the Byzantine Empire, in the area of today’s Greece, before 1200. Thanks to a rising number of accounts about Roma by the settled population from 1400 onwards, their routes within Europe can today be traced quite precisely. In 1450, the Roma had travelled almost the whole of Europe. In Central Europe, the first deportations and expulsions were already taking place at that time. Soon this would lead to organised persecution.
