In this universal confusion the Turks first make good a footing in Bosnia. Already in the reign of Stephen Dabiscia, Bajazet had advanced into the county of Chelm and established stationary quarters at a spot become memorable in the most recent times as the scene of the first outbreak of a revolt which has shaken Turkish dominion in Bosnia to its foundations—Nevešinje.[92] But in the factious contests which distracted the reign of the third Tvartko, each of the competitors for dominion outbade the other for Turkish help, and it was by the direct invitation and under the actual leadership of a turbulent noble that the Turks first gained sufficient footing in Bosnia to establish there a Sandjakate. The whole story is worth repeating, as it singularly illustrates the state into which this unhappy country had fallen. At the time there were two kings in Bosnia; Tvartko, who had now made his peace with Sigismund and ruled over the parts of Bosnia along the Drina and the Serbian frontier, and Ostoja, who owed his elevation to the Neapolitan faction of Ladislaus, and whose territory embraced the maritime parts and a tract roughly answering to the later Herzegovina. Between the Eastern and the Western kingdom lay a more or less neutral wedge of country which had been carved out by King Sigismund and formed into a Hungarian Banat under the great Croatian noble Hervoja Horvatić, whose dominion included the city of Jaycze, and anticipated in its extent that Banat of lower Bosnia which, at a later time, Mathias Corvinus recovered from the Turkish conqueror. Hervoja, who assumed the title of Chief Voivode, and even Prince, of Bosnia,[93] and who shifted his allegiance, as the whim seized him, from Tvartko and Sigismund to Ostoja and Ladislaus, happened on one occasion to have honoured King Sigismund with his presence at his court. Hervoja, who added a bullying manner to a body of bovine dimensions, was haranguing the assembled magnates, Hungarian and Bosnian, in his usual tones, when a certain Paul Chupor, Ban of Slavonia, broke in upon his lordship by bellowing like a bull. This was too much for the gravity of court ceremonial, and King Sigismund himself could not help joining in the general laugh. But Hervoja, in a frantic rage, left the court, and hurried back to his Banat, vowing vengeance against the Hungarian King, his Bosnian liegeman King Tvartko, and every baron who followed their banners. Seizing the opportunity when both of them were away in Germany, he called in the Turks and took the command of the invading horde in person. In the absence of the two Kings, the magnates of the country, with his mortal enemy, Paul Chupor, at their head, united their retainers to oppose him. Hervoja defeated their army, and having the luck to take his old insulter prisoner, had him sewn up alive in a bull’s hide and thrown into the river, with the characteristic jest, ‘When thou wert a man thou didst speak with a bull’s voice; take now thy bull’s hide as well!’
