Eritrea Religion is centred round two main religions, Christianity and Islam. In Christian community also, there is a division between Lutheran Protestants, Orthodox Church and Roman Catholic. In the capital city of Asmara and the high lands, majority of the population is predominantly Christian, whereas in the lowlands and the coastal area, most of the residents are Muslims. Apart from this, there is also a small community of Kunamas practicing their own traditional religion. They are mainly seen to worship Anna, who is considered to be the creator and idolatry of ancestral heroes. However, this diversity of religion in Eritrea never created obstacles to disturb the peace and harmony of the nation. Other religions are Seventh-day Adventists, Jehovah's Witnesses, Baha'is, and some there.
Since the forth century A.D., Axum has converted to Christianity. On the other hand, Islam spread to Eritrea about 615 AD as soon as Osman Bin Afan arrived there.
On the other hand, in 1600, Catholicism was first introduced in Eritrea by the Jesuit Fathers. Again, in the nineteenth century, the Italians started bringing Eritrea under their protection and brought Roman Catholicism to the country with them. The protestant presence in Eritrea is small. Missionaries appeared in the 19th century and established the Lutheran and Evangelical church. These organizations have been allowed to continue to practice. New groups however, have been discouraged from establishing a base in Eritrea. In Eritrea, mainly four religious groups are officially sanctioned. Those include: Orthodox church, Muslims, Evangelical Church and Catholics
In Eritrea, any one belonging to the Muslim, Catholic, Orthodox or Evangelical church, is given the opportunity to breathe in fresh air. This is probably the reason that Eritrea n people never underwent severe problem related to religion.
