Previous to this, the Turks had frequently menaced the Bosnian kingdom, but it was not until June 14, 1463, that they actually invaded the country, to reduce Stephen to obedience. In vain did Mathias, King of Hungary, endeavour to stem the advancing torrent. The Turks carried all before them, until they besieged and took Yanitza, the then capital of the province, and with it the King and the entire garrison. Nor was this effected in fair fight, but through the treachery of Stephen's first minister, who opened the gates of the fortress by night, and so admitted the Turkish soldiers. With more generosity than was usually shown by these Eastern barbarians, Mahomet agreed to leave the King in possession of his throne on condition of his paying an annual tax to the Porte. The payment of this, as I have said, was evaded by his successor, although the old national manuscripts do not even allow this apology for the barbarous treatment which he experienced at the hands of the Turks. These affirm that the King and all his troops, as well as the townspeople, were invited by Mahomet to hear the official ratification of the agreement. But, at a given signal, the Turkish soldiers, who had been in concealment, fell upon the helpless assemblage, and massacred them in cold blood, shutting up the King Stephen in a cage, where he subsequently died of despair; and thus ended the Bosnian kingdom. That his position was sufficiently hopeless to bring about this calamitous result, can scarcely be doubted; but unfortunately the tomb of Stephen still exists, which proves tolerably conclusively that his death was of a more speedy, if not of a more cruel, nature. An inscription is upon it to the effect, 'Here lies Stephen, King of Bosnia, without his kingdom, throne, and sceptre, and without his skin.' Of all the family of the unfortunate monarch, the only one who escaped was his Queen, Cattarina, who fled to Rome, where she lies buried in the Chapel of Santa Helena. After the death of Stephen Thomasovich the Turks destroyed Michiaz. The nobles, driven from their estates, fled to Ragusa; and Stephen, 'Herzog' or Duke of Santo Saba, seeing that Turkish garrisons had occupied Popovo, Rogatiza, Triburio, Tzeruitza, and Kerka, became so alarmed, that he offered to pay increased tribute; when, his ministers refusing to consent to this arrangement, he was obliged to send to Ragusa for his eldest son Stephen, and give him up as a hostage to the Porte: he having afterwards abjured Christianity, received the name of Ahmet, married a daughter of Bajazet II., and was made a Vizier. The Kingdom of Bosnia and the Duchy of Santo Saba from that time became provinces of Turkey, the latter under the name of Herzegovina, which it still retains, and which it had received from the title of 'Herzog' or Duke, given by Tuartko to its first Governor.
