In regard to religion, some of the Altai remain Shamanists and others (in a trend beginning in the mid-19th century) have converted to the Russian Orthodox Church. The Altai mission was developed under Saint Makarii Glukharev († 1847), known as the 'Apostle to the Altai'.[citation needed] In 1904, a religious movement called Ak Jang or Burkhanism arose among these people.[18]
