What Roydosan points out is elementary to anyone who has even read just one basic scholarly work on The Roman Empire, that is, the Universalism (even before the Constitutio Antoniana), which existed primarily between Hellenistic East and some areas of the Latin West.

However, Wikipedia is not for Byzantologists or Roman Historians, it's for the everyman. The everyman DOES immediately associate Latin and Roman, it's just something that's embedded largely because of the fact Byzantium has always been ignored as far as education goes.
