Islam is the dominant religion in Libya. Other than the vast majority of Sunni Muslims, there are also small Christian communities, composed exclusively of immigrants. Coptic Orthodox Christianity, which is the Christian Church of Egypt, is the largest and most historical Christian denomination in Libya. There are over 60,000 Egyptian Copts in Libya, as they comprise over 1% of the population alone. There are an estimated 40,000 Roman Catholics in Libya who are served by two Bishops, one in Tripoli (serving the Italian community) and one in Benghazi (serving the Maltese community). There is also a small Anglican community, made up mostly of African immigrant workers in Tripoli; it is part of the Anglican Diocese of Egypt. Libya was until recent times the home of one of the oldest Jewish communities in the world, dating back to at least 300 BC. A series of pogroms beginning in November 1945 lasted for almost three years, drastically reducing Libya's Jewish population. Religious freedom Religious liberties The Libyan constitution states that Islam is the state religion and that Sharia is the primary source of legislation. However, under sharia law, freedom of religion is guaranteed to Christians and Jews (including the right to govern familial matters such as divorce and inheritance) and discrimination on the basis of religion is prohibited. Religious minorities other than Christians and Jews are not granted the same religious freedom under Libyan law. Regarding conversion from one religion to another, there is no protection of the right to do so or explicit prohibition of conversion away from Islam or proselytizing, however missionary work and conversion are effectively prohibited. Libyan law prohibits insulting Islam and the Prophet Muhammad, as well as publications that aim to "change the fundamental principles of the constitution or the fundamental rules of the social structure." These laws are used to deter missionary work as well as the circulation of non-Islamic religious materials. Religiously motivated violence The rights of religious minorities provided by Libyan law are often violated and religiously motivated violence is common. Religious minorities can face intense pressure to convert or revert to Islam, especially in areas controlled by Salafist militant groups. Non-Muslims face heightened risk of violence (including sexual assault) in refugee detention centers and one Christian refugee reported that the guards treated refugees from Morocco, a Muslim-majority country, better.
