From Bosnia, their influence extended into Italy (Piedmont). The Hungarians undertook many crusades against the heretics in Bosnia, but towards the close of the 15th century, the conquest of that country by the Turks put an end to their persecution. Few or no remnants of Bogomilism have survived in Bosnia. The Ritual in Slavonic written by the Bosnian Radoslav, and published in vol. xv. of the "Starine of the South Slavonic Academy at Agram", shows great resemblance to the Cathar ritual published by Cunitz, 1853.
