The Byzantines broadly grouped the numerous Slav tribes living in proximity with the Eastern Roman Empire into two groups: the Sklavenoi and the Antes. The Late Roman historians, Jordanes and Procopius both locate the Sklavenoi in the lower Danube (modern Wallachia and Moldavia), although Sklavi subsequently in Latin sources in connection to events in Lombard Italy. Whilst there were many Sklaveni, the Antes were a specific ethicon who had a foedus with the Byzantine Empire, and were probably located in Scythia Minor.
