There is a history of persecution of Muslims in Myanmar that continues to the present day. Myanmar is a Buddhist majority country, with significant Christian and Muslim minorities. While Muslims served in the government of Prime Minister U Nu (1948–63), the situation changed with the 1962 Burmese coup d'état. While a few continued to serve, most Christians and Muslims were excluded from positions in the government and army. In 1982, the government introduced regulations that denied citizenship to anyone who could not prove Burmese ancestry from before 1823. This disenfranchised many Muslims in Myanmar, even though they had lived in Myanmar for several generations.
