Hutton Webster, Early European History
“ The development of Roman law carried its principles of justice and equity to the remotest regions. The spread of the Latin language provided the western half of the empire with a speech as universal there as Greek was in the East. Trade and travel united the provinces with one another and with Rome. The worship of the Caesars dimmed the luster of all local worships and kept constantly before men's minds the idea of Rome and of her mighty emperors. Last, but not least important, was the fusion of alien peoples through intermarriage with Roman soldiers and colonists. ”
