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 <sup>th</sup> and 14 <sup>th</sup> 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.
