research has shown that Christianity existed after the Muslim conquests, though the Catholic church gradually declined along with local Latin dialect. Many causes have been seen as to leading to the decline of Christianity in Maghreb. One of them is the constant wars and conquests as well as persecutions. In addition many Christians also migrated to Europe. The Church at that time lacked the backbone of a monastic tradition and was still suffering from the aftermath of heresies including the so-called Donatist heresy, and that this contributed to the early obliteration of the Church in the present day Maghreb. Some historians contrast this with the strong monastic tradition in Coptic Egypt, which is credited as a factor that allowed the Coptic Church to remain the majority faith in that country until around after the 14th century despite numerous persecutions. In addition, the Romans and the Byzantines were unable to completely assimilate the indigenous people like the Berbers. Another view is that Christianity in North Africa ended soon after conquest of North Africa by the Islamic Umayyad Caliphate between AD 647–709 effectively. However, new scholarship has appeared that disputes this. There are reports that Christianity persisted in the region from Tripolitania (present-day western Libya) to present-day Morocco for several centuries after the completion of the Arab conquest by 700. A Christian community is recorded in 1114 in Qal'a in central Algeria. There is also evidence of religious pilgrimages after 850 to tombs of Christian saints outside of the city of Carthage, and evidence of religious contacts with Christians of Arab Spain. In addition, calendrical reforms adopted in Europe at this time were disseminated amongst the indigenous Christians of Tunis, which would have not been possible had there been an absence of contact with Rome. Local Catholicism came under pressure when the Muslim fundamentalist regimes of the Almoravids and especially the Almohads came into power, and the record shows persecutions and demands made that the local Christians of Tunis to convert to Islam. We still have reports of Christian inhabitants and a bishop in the city of Kairouan around 1150 – a significant report, since this city was founded by Arab Muslims around 680 as their administrative center after their conquest. A letter from the 14th century shows that there were then still four bishoprics left in North Africa, albeit a sharp decline from the over four hundred bishoprics in existence at
