This is unique because this is the only way to rediscover a lost culture aside from custom nations and console commands. Ironically the Roman Empire can reform into the Holy Roman Empire by becoming emperor of the HRE and revoking the privilegia and centralising the Empire.Īdditionally, the Roman Empire has a very special effect upon formation, as it will convert all provinces of the nation's primary culture group to Roman Culture and set that as the primary culture. The other way to play the Roman Empire is to restore the Roman Empire as Byzantium in Crusader Kings II and converting the save to EU4 using the Europa Universalis 4 Save Converter. Any Christian or Pagan nation other than the Holy Roman Empire or the Papal States can restore the Roman Empire by decision after re-conquering most of the historical Empire. While the Western Roman Empire ceased to exist long before the era covered by Europa Universalis IV, the Eastern Roman Empire continued to survive as Byzantium. Historically, the Roman Empire was the dominant great power in Europe in the first few centuries AD and the first major empire of its kind and left behind a legacy that would form the very foundation for European civilisation of subsequent ages.
