The East Roman Age covers the period of time where Greco-Roman culture was dominant in the East Mediterranean. The East Roman age started after the fall of the East Roman Empire in 840 AD and it ended in 1410 AD, when the last East Roman successor kingdom fell. During this time Greek culture was spread all through out the Mediterranean and most areas in the east became greek speaking if they were not already. This led what ever successor kingdom or empire have to take up Greek traditions and language as they effectively spread Greek culture all across the east. Progress in many different fields took place, such as the advancing arts, science, civil reform, religions, public works and theatre to name a few.
