Europe didn't exist as a cultural concept at that time. There was Rome, but that was a Mediterranean empire with hugely significant southern European, east Asian, and north African components. Citizens and elites came from all parts.
Eventually, we get a Europe united under Christianity, but I wouldn't call that fully developed until the end of the Viking age.
