Coptic Christians are members of the Coptic Orthodox Church, one of the oldest Christian denominations in the world. They primarily reside in Egypt, where they make up about 10% of the population. The Coptic Church traces its origins to the apostle Mark, who is believed to have brought Christianity to Alexandria in the first century. Copts have a rich cultural heritage, including unique traditions, art, and music. They celebrate their own religious holidays and follow a distinct liturgical calendar. The Coptic language, derived from ancient Egyptian, is still used in church services, preserving a link to their historical roots.
