Rome throughout history is often thought of as rather homogeneous—ancient artifacts timeless, always the same emphases. But, while there were continuities, there were also changes of different sorts in various time periods. Specifically, cultural and political changes in the Roman civilization between 100-600 CE, the late classical era, included the rise of Christianity and the division of the empire into two halves, while a continuity was the use of Latin and Greek as common languages. The first change, Christianity spreading throughout the civilization, is shown in the development and spread of Greek Orthodox and Roman Catholic lifestyles. Constantine legalized Christianity in the fourth century AD, and soon after, Theodosius made it the empire’s official religion.

After this, as a result, a new controversy arose: the classic one of the separation of church and state. The unified Christian lifestyle was very different from the previously religiously-tolerant classical Roman Empire. The next change is that the empire soon split in half. Rome became simply too large to govern under one governmental body, and so split into the Eastern and Western halves in 284. These two had separate governments and separate religions (Greek Orthodox and Roman Catholicism respectively). Also, the halves were relatively independent from each other, fighting their own battles and having different levels of advancement in science, technology, and more.
