That would be the Roman province of Judea, though people were first called Christians in Antioch (which might have been in a different province).
Christianity
The term Byzantine Empire is used to indicate the eastern part of the empire after the fall of the western part.
Of course, the most fundamental effect today, of the rise of Christianity in the Roman Empire, is that most Westerners are Christians. The political map of Europe has been drawn and redrawn as pagans were conquered in the name of Christianity and political changes resulted from long-ago alliances and emnities of religious origin. While the conquest of South America was primarily driven by greed, its division into a Spanish west and a Portuguese east was mediated by the Christian Pope. A more subtle effect, not so much of the mere fact of the rise of Christianity, but of the manner of its rise and the culture of intolerance and persecution that arose with it in the fourth-century empire, is that even today we have an underlying culture of intolerance when compared to pagan times or to the Orient.

During his reign as emperor, Augustus did not do too much to expand the empire. Egypt, in 30 BC, was his addition. He concentrated upon consolidating the empire, and even pulled back the frontier after the Varus disaster. During his reign trouble arose in Panonia, Gaul, Spain, the mid east and Germany.

Western Europe (Eastern part of the Roman Empire did not collapse and became known as the Byzantine Empire) went into a period of chaos, then arose in the feudal society (Middle Ages)

Pagan Rome
Islam did not contribute to the fall of Rome and the western part of the Roman Empire. This part of the empire fell more than a century before the rise of Islam. This religion contributed to the fall of the eastern part of the Roman Empire (which historians all Byzantine Empire) which existed for nearly 1,000 years after the fall of the western part. It united the Arabs, who went on to take over the Roman territories in Jordan, Palestine, Lebanon, Syria and North Africa. The Ottoman Turks took over Turkey and the European territories and conquered the Capital, Constantinople, bringing down this empire. They were Muslims. However, power, rather than religion was their motivation. Christianity did not play a part in the fall of the Roman Empire, be it the western part or the eastern part. It became the state religion and part of the fabrics of state and society. Some pagan Roman thought that Christianity had weakened the fighting spirit of the Romans, but this was not the case.
The three religions that arose in the Middle East are Judaism, Christianity, and Islam.

The Roman Republic was followed by 503 years of rule by emperors.
Constantinople was the capital of the Byzantine Empire, which arose from the eastern part of the Roman Empire after its division. Founded by Emperor Constantine the Great in 330 AD, the city became a major cultural and economic center, reflecting the empire’s blend of Roman and Greek influences. The Byzantine Empire, known for its Christian orientation, governance, and art, thrived in Constantinople until its fall in 1453. Thus, Constantinople served as the heart of Byzantine power and culture.
