Dabisa, his young son, under the regency of his widow, Helena, and then Stephen Ostoja. The most powerful man in Bosnia was the Vojvode Hrvoje Vukcić, who ruled the north, and next to him was his kinsman Sandalj Hranić who dominated the south. Both of these men were Cathari, and so was the king, Stephen, Ostoja, and all his family. Catholicism almost disappeared, and Catharism was the religion of the State. It was organized under a Djed (grandfather), or chief, with twelve Ucitelji, or teachers, of whom the first was the Gost, or visitor, the deputy and successor of the Djed, and the second was known as the Starac, or elder.[340] These were state officials, and we see them occasionally acting in an official capacity. Thus, when, in 1404, the Vojvode Paul Klesić, who had been exiled, was recalled, it was the Djed Radomjer who sent Catharan envoys to Ragusa to bring him home, and who wrote to the Doge of Ragusa on the subject. Klesić was a Catharan, and his residence in Ragusa, as well as that of many similar Catharan exiles, shows that persecution had grown obsolete even on the coast of the Adriatic. In spite of his Catharism, Hrvoje Vukcić was made by Ladislas of Naples, Duke of Spalatro and lord of some of the Dalmatian islands, thus making Catharism dominant along the shore. In the troubles which ended in the deposition of Stephen Ostoja and the election of Stephen Tvrtko II. a “Congregation of the Bosnian Lords” was held in 1404, in which, among those present, are enumerated the Djed and several of his Ucitelji, but no mention is made of any Catholic bishop. Toleration seemed to have established itself. The Great Schism gave the Holy See abundant preoccupation, and missionary efforts are no longer heard of, until the Emperor Sigismund, as King of Hungary, bethought himself of re-establishing his claim over Bosnia. Two armies sent in 1405 were unsuccessful, but in 1407 Gregory XII. aided him with a bull summoning Christendom to a crusade against the Turks, the apostate Allans, and the Manichæans. Under these auspices, in 1408, he led a force of sixty thousand Hungarians and Poles into Bosnia, defeated and captured Tvrtko II., and recovered Croatia and Dalmatia, but the Bosnians were obstinate, and replaced Ostoja on the throne. Another expedition, in 1410-1411, drove Ostoja to the south, and Sigismund, for a while, retained possession of Bosnia, but when, in 1415, he released Tvrtko II. and sent him to Bosnia as king, a civil war immediately ensued. Tvrtko at first was successful, supported with a large Hungarian army, but Ostoja called the Turks to his assistance, and in a decisive battle the Hungarians were defeated. The Turks penetrated to Cillei in the Steyermark, devastating and plundering everywhere, and on their return carried with them thousands of Christian captives.[341]
