Editing Carniola (section)

===Ecclesiastical history===
In early Christian times the duchy was under the jurisdiction of the [[metropolitans of Aquileia]] (who became Patriarchs), Syrmium, and Salona. In consequence of the immigration of the pagan Slovenes, this arrangement was not a lasting one. After they had embraced Christianity in the seventh and eighth centuries Charlemagne conferred the major part of Carniola on the Patriarchate of Aquileia, and the remainder on the [[Diocese of Trieste]]. In 1100 that patriarchate was divided into five archdeaconries, of which Krain was one.<ref name=CE/>

The diocese of Ljubljana or Laibach was established by Emperor Frederick III on 6 December 1461. It was directly subject to the pope. This was confirmed by a Bull of Pope Pius II, 10 September 1462. The new diocese consisted of part of Upper Carniola, two parishes in Lower Carniola, and a portion of Lower Styria and Carinthia; the remaining portion of Carniola was attached to Aquileia, later on to [[Gorizia]] and [[Trieste]]. At the redistribution of dioceses (1787 to 1791) not all the parishes in Carniola were included in the Diocese of Ljubljana, but this was accomplished in 1833, by taking two deaneries from the Diocese of Trieste, one from Gorizia, and one parish from the Diocese of Lavant, so as to include all the territory within the political boundaries of the crownland.<ref name=CE/>
