Latin Sources on the Religious Situation in the Western Mongol Uluses in the late 13 <sup>th</sup> - early 14 <sup>th</sup> centuries
The present study considers the development of Catholic apostolate in the Mongol Empire in the 13 th and 14 th centuries as integrated harmoniously into the generic competition of world religions on the nomads’ conversion. This paper reflects the actual state of present research including a description of its two central points that concern both information on the extent of the Catholic apostolate in the East and the methods of Gospel preaching among the nomads.
