URGA, MISSION OF. - It comprises all of Outer Mongolia, a region never before evangelized due to the extremely difficult conditions of travel across the Gobi Desert and the obstacles posed by the Russian government of the tsars. After their fall, greater religious freedom was hoped for.
Moreover, modern means of communication facilitated contact with that land. Therefore, on March 14, 1922, the "sui iuris" Mission of Outer Mongolia was erected, with territory detached from the Apostolic Vicariate of Central Mongolia (Diocese of Siwantze) and entrusted to the CICM Missionaries. By decree of December 3, 1924, it received the name "Mission of U." [Urga], the country's capital. However, as the region had fallen under Soviet Russian control, the missionaries were never able to enter II. A report from 1921 states that the number of Catholics reached about a hundred among merchants and emigrants.
