Christianity is a small minority in Mauritania. All of the roughly 4,500 Roman Catholics in Mauritania are within the country's only diocese, the Roman Catholic Diocese of Nouakchott. There are several expatriate African churches in Mauritania, though there are no more than 200 Protestants in the country, including foreigners.
The distribution of Christian literature and the evangelizing of Muslims are prohibited by law. Bibles are rarely printed or distributed. State oppression has included the arrest of Mauritanian Christians due to their religious beliefs and the closure of churches. Conversion from Islam is punishable by death and other religions are not recognized by the state.
