モンゴルの国教は何？
Religion in Mongolia has been traditionally dominated by the schools of Mongolian Buddhism and by Mongolian shamanism, the ethnic religion of the Mongols. Historically, through their Mongol Empire the Mongols were exposed to the influences of Christianity (Nestorianism and Catholicism) and Islam, although these religions never came to dominate. During the socialist period of the Mongolian People's Republic (1924-1992) all religions were suppressed, but with the transition to the parliamentary republic in the 1990s there has been a general revival of faiths.
