Charlemagne increased the size of the Frankish kingdom to include most of the area of present France, Belgium, the Netherlands, Germany, and Switzerland, and parts of Austria, Italy, and Spain. It was the largest country in Western Europe since the Roman Empire, and much larger than any there today. On December 25, 800, Pope Leo III crowned him Emperor of the Romans, in an effort to reestablish the West Roman Empire. His country did not survive him for long, however, as it was divided among his grandsons. Nevertheless, the countries they began included France and the Holy Roman Empire.

The art of the eastern and western parts of the Roman Empire were similar because in both parts of this empire it was Greco-Roman art. This is a term which indicates the fact that Roman art became heavily influenced by Greek art. Greek art had already influenced the eastern Mediterranean before it was taken over by the Romans because the Greeks had ruled this area for three hundred years prior to this. The Romans spread Greco-Roman art in the western part of the empire. It has to be noted that, however, many of the local peoples in the empire retained their traditional art.
I would say religion was the ancient Romans' most significant contribution to Europe. Christianity developed from a religion among a small group of Jews (who lived in Judea, which was part of the Roman Empire) into a mass religion in the Roman days. It spread around the Roman Empire. It became state religion. Catholic Christianity and Orthodox Christianity developed during the Later Roman Empire. They were originally called Latin or Western Christianity and Greek or Eastern Christianity respectively. The former was the main form of Christianity in the western part of the Roman Empire and the latter was the main form of Christianity in the eastern part of the Roman Empire.
The most famous early historian on the subject is Edward Gibbon who lived in the 18th century and who wrote the still-famous History of the Decline and Fall of the Roman Empire.
