the lower nobility and the peasantry, however, were far less well-disposed to reforms. the croatian priesthood was aligned towards byzantine orientalism, including having long beards and marrying. more so, the ecclesiastical service was likely practiced in the native slavonic (glagolitic), whereas the pope demanded practice in latin. this caused a rebellion of the clergy led by a certain priest named vuk ("ulfus"), who was referenced as newcomer to the kingdom in sources. vuk had presented the demands and gifts of the croats to the pope during his stay in rome, but was told nothing could be accomplished without the consent of the split see and the king. they protested against celibacy and the roman rite in 1063, but they were proclaimed heretical at a synod of 1064 and excommunicated, a decision which krešimir supported. krešimir harshly quelled all opposition and sustained a firm alignment towards western romanism, with the intent of more fully integrating the dalmatian populace into his realm. in turn, he could then use them to balance the power caused by the growing feudal class. by the end of krešimir's reign, feudalism had made permanent inroads into croatian society and dalmatia had been permanently associated with the croatian state.
