After the Turkish conquest of Bosnia the history of the Bogomiles in those parts becomes obscure. That they still existed in the revived Banat of lower Bosnia we may gather from a passage in the ‘Annals of the Minorites,’[75] to the effect that in 1478 the city of Jaycze was ‘polluted by heretics and schismatics.’ Many who had resisted the propaganda of Rome appear to have found in the iconoclastic puritanism of Islâm a belief less incompatible with their own. We have direct evidence that it was the Bogomiles who chiefly swelled the ranks of the renegades.[76] Many, doubtless, when they found how hard were the masters they had called in, were provoked to their old attitude of resistance, and perished for their obstinacy. They are generally said to have died out, and the Bosnian monks of the order of St. Francis, who, in 1769, supplied the author of ‘Illyricum Sacrum’ with an account of the present state of that country, declare that there are no traces left of them. This, however, is not the case. During the recent insurrection, over 2,000 Bogomiles from Popovo, a single district of the Herzegovina, took refuge in the hospitable territory of what was once the Republic of Ragusa.[77] To return to the more secular aspects of Bosnian history. Much still remains to be elucidated by Sclavonic historians with regard to the inner government of the country, the rise of the semi-feudal nobility, and the complicated relations of parties. Here it would be hopeless to attempt anything more than the merest outline, giving prominence only to a few episodes of general interest. The Hungarian overlordship is occasionally broken by a Serbian, and Stephen Dūshan, who, in the middle of the fourteenth century, revived the Czardom among the Balkan Sclaves, seized the pretext of a claim on the Principality of Chelm to overrun Bosnia, and add its dominion to his titles. For an interesting monument of this period I may refer the reader to the account of the Book of Arms of Bosnian Nobility, drawn up in the year 1340 by order of the Serbian Czar, which we saw in the Franciscan Monastery of Foinica.[78]
