Simply put: Islam was developed first.
Not so Simply: Technically Islam formed before Christianity dating back to Abraham(2050-2000 B.C.. One of the major splitting points for Islam is when Abraham gave the blessing to Isaac(younger Son from sarah) instead of Ishmael( First son of Hagar, Sarah's housemaid). Muslims see Ishmael as a Prophet. The Islamic people believe it was to Ishmael that God called upon sacrifice instead of Isaac. Ishmael had 12 sons that grew into 12 tribes. Many see Ishmael as the patriarch of the Arab People. Christianity is formed by Christ's teachings ( anywhere from 33 B.C.- 33 A.D. due to historical error) and his death and resurrection. Muslims see Christ as another prophet, yet not the Son of God. The Jewish Community do not accept Christ as the son of God and savior. Christians believe Christ is the Son of God and Savior.
The main religions are Buddhism, Hinduism, Judaism, Christianity and Islam. The first two are polytheistic and the last three are monotheistic. Judaism, Christianity and Islam all have major divisions and sects. I don't know if the same could be said about Buddhism and Hinduism as I have not studied them.

All the prophets in the Old Testament are revered and studied by both Christians and Hebrew people. Sometimes other religions will borrow from the prophets of the Old Testament but they do not deem the Bible as being authoritative like Judaism and Christianity does. Islamic and Jewish tradition view Jesus as a prophet. Christianity sees him as a part of the holy trinity.
Monasteries were places where monks studied christian works and they preserved and promoted the ideas and beliefs of Christianity.
There was only one Roman Empire. Moreover, the Roman Empire did not study Christianity. An empire cannot study. The Roman Empire was where Christianity spread from Judea (which was a part of the Roman province of Syria). Both Catholic and Orthodox Christianity developed in the Roman Empire. Originally the were called Latin or Western Christianity and Greek or Eastern Christianity respectively. The former was the dominant form of Christianity in the western part of the Roman Empire and the latter was the dominant form of Christianity in the eastern part of this empire. There were also dissident Christian doctrines and sects.
