"The Byzantine Empire, a blend of Roman polity, Greek culture and the Christian faith, succeeded in its 1000-year lifespan in creating a culture that is still interesting to numerous people to this very day. The first university in Byzantium was founded by Theodosius II in 425, while the first higher education institution in the Latin West was founded much later, in Bologna in 1118, and today it is the oldest university in Europe."
