On the death of Ninoslav in 1250, vigorous efforts were made to exterminate the Bogomil heresy; and to this end, Bela IV., who appeared as the champion of Roman Catholicism, Hungarian' secured the election of his nominee Prijesda to the banate.
A rising of the native magnates in 1322 resulted in the election of the Bogomil, Stephen Kotromanic, last and greatest of the Bosnian bans.
His position was endangered by the growing power of his father-in-law, Stephen Vukcic, an ardent Bogomil, who had united Tribunia and Hlum into a single principality.
Similarly (in a iothcentury form of renunciation of Bogomil error preserved in a Vienna codex 1) we hear of Peter "the founder of the heresy of the Messalians or Lycopetrians or Fundaitae and Bogomils who called himself Christ and promised to rise again after death."
It is difficult to ascertain whether the name was taken from the reputed founder of that sect, a certain pope Bogumil or Bogomil, or whether he assumed that name after it had been given to the whole sect.
Though these writings are mostly the same in origin as are known from the older lists of apocryphal books, they underwent in this case a certain modification at the hands of their Bogomil editors, so as to be used for the propagation of their own specific doctrines.
The Bogomil propaganda follows the mountain chains of central Europe, starting from the Balkans and continuing along the Carpathian Mountains, the Alps and the Pyrenees, with' ramifications north and south (Germany, England and Spain).
