The evil effects of Tvrtko’s death were soon felt. His younger brother, or cousin[898], Stephen Dabisha, who succeeded him, felt himself too feeble to govern so large a kingdom, and in 1393 ceded the newly won lands of Dalmatia and Croatia to King Sigismund of Hungary. The two monarchs met at Djakovo, in Slavonia, and concluded an agreement by which Sigismund recognised Dabisha as King of Bosnia, while Dabisha bequeathed the Bosnian crown after his death to Sigismund. A combination of Bosnian magnates and Croatian rebels, however, refused to accept these terms, and Dabisha himself broke the treaty which he had made. An Hungarian invasion of his Kingdom and the capture of the strong fortress of Dobor, on the lower Bosna, at once reduced him to submission, and a battle before the walls of Knin, in Dalmatia, finally severed the brief connection between that country and the Bosnian throne. To complete Dabisha’s misfortunes, the Turks, who had been in no undue haste to make use of their victory at Kossovo, invaded Bosnia for the first time in 1392, and gave that country a foretaste of what was to come.
On Dabisha’s death in 1395 the all-powerful magnates, disregarding the treaty of Djakovo, made his widow, Helena Gruba, regent for his son. But they retained for themselves all real power, governing their domains as almost independent princes, maintaining their own courts and issuing charters, coining their own money and negotiating on their own account with foreign states, such as the Republics of Venice and Ragusa. One of their number, Hrvoje Vuktchich, towered above his fellows, and his career may be regarded as typical of his troublous times. For the next quarter of a century Bosnian history is little else than the story of his intrigues, and the neighbouring lands of Dalmatia and Croatia felt his heavy hand. Even Sigismund, King of Hungary, and his Neapolitan rival, Ladislaus, were bidding against one another for his support, and at the end of the fourteenth century he was “the most powerful man between the Save and the Adriatic, the pillar of two Kings and Kingdoms.” The shrewd Ragusans wrote to him that “whatsoever thou dost command in Bosnia is done”; the documents of the period style him regulus Bosnensis, or “Bosnian kinglet”; he called himself “the grand voivode of the Bosnian Kingdom and vicar-general of the most gracious sovereigns King Ladislaus and King Ostoja, the excellent lord, the Duke of Spalato.” The three great islands of Brazza, Curzola, and Lesina, and the city of Cattaro owned his overlordship, and his name will always be connected with the lovely town of Jajce, at the confluence of the Pliva and the Vrbas, the most beautiful spot in all Bosnia. Here, above the magnificent waterfall on the hill, for which in olden times the Bosnian bans and the Croatian Kings had striven, Hrvoje bade an Italian architect build him a castle. Whether the town of Jajce, “the egg,” derives its name from the shape of the hill or from the fact that the castle was modelled on the famous Castello dell’ Uovo at Naples, is doubtful. But he is now regarded as the founder of the catacombs, which still bear his arms and were intended to serve as his family vault[899]. For his capital of Spalato he even issued coins, which circulated in Bosnia as freely as the currency of the puppet kings whom he put on the throne. What Warwick the king-maker is in the history of England, what the mayors of the palace are in the history of France, that is Hrvoje in the annals of mediæval Bosnia. An ancient missal has preserved for us the features of this remarkable man, whose gruff voice and rough manners disgusted the courtly nobles of the Hungarian court. But the uncouth Bosniak took a terrible revenge on his gentle critics. When a wit made fun of his big head and deep voice by bellowing at him like an ox, the company laughed at Hrvoje’s discomfiture. But when, a little later, the fortune of war put the jester in his power, Hrvoje had him sewn into the skin of an ox and thrown into the river, with the words, “Thou hast once in human form imitated the bellowing of an ox, now therefore take an ox’s form as well.”
The great Turkish invasion, which took place in 1398 and almost entirely ruined Bosnia, convinced the great nobles that a woman was unfitted to rule. Headed by Hrvoje, they accordingly deposed Helena Gruba, and elected Stephen Ostoja, probably an illegitimate son of Tvrtko, as their King. So long as Ostoja obeyed the dictates of his all-powerful vassal he kept his throne. Under Hrvoje’s guidance he repulsed the attack of King Sigismund of Hungary, who had claimed the overlordship of Bosnia in accordance with the treaty of Djakovo, and endeavoured to recover Dalmatia and Croatia for the Bosnian crown under the pretext of supporting Sigismund’s rival, Ladislaus of Naples. But the latter showed by his coronation at Zara as King of both those lands that he had no intention of allowing them to become Bosnian possessions, as in the days of Tvrtko. Ostoja at this changed his policy, made his peace with Sigismund, and recognised him as his suzerain. But he had forgotten his maker. Hrvoje, aided by the Ragusans, laid siege to the royal castle of Bobovatz, where the crown was preserved, and when Sigismund intervened on behalf of his puppet summoned an “assembly” or “congregation of the Bosnian lords” in 1404 to choose a new King. This great council of nobles, at which the djed, or primate of the Bogomile church, and his suffragans were present, is frequently mentioned at this period, and contained in a rude form the germs of those representative institutions which in our own country sprang from a like origin. Hrvoje easily persuaded the council to depose Ostoja and elect Tvrtko II, the legitimate son of Tvrtko I, in his place. But Sigismund was not so lightly convinced. After a first futile attempt he sought the aid of the Pope in a crusade against “the renegade Arians and Manichæans” and marched into Bosnia in 1408 at the head of a large army. Tvrtko II met him beneath the walls of Dobor, on the same spot where, fourteen years before, another great battle had been fought. Once again the Bosnian forces were defeated. Sigismund took Tvrtko as his prisoner to Buda-Pesth, after beheading 126 captive Bosnian nobles and throwing their bodies into the yellow waters of the Bosna. The victory had decisive results. Hrvoje humbled himself before the King of Hungary, and Ladislaus of Naples sold all his rights to Dalmatia to the Venetians in despair. But the national party in Bosnia was not so easily dismayed. Nothing daunted by the defeat of Tvrtko and the desertion of Hrvoje, they restored Ostoja to the throne. Utter confusion followed. Sigismund dismembered the country, placing Usora and Soli again under Hungarian bans, bestowing the valuable mining district of Srebrenitza upon the Despot of Serbia to be an apple of discord between the two Serb states, and leaving Ostoja the Herzegovina and South Bosnia alone, while even there every one did what was right in his own eyes, and members of the royal family lived by highway robbery. Well might the Ragusans complain that “our people travel among the Turks and other heathen, yet nowhere have they met with so much harm as in Bosnia.” Yet one step lower was Ostoja to fall. Hard pressed by the Hungarians and his released rival Tvrtko, he summoned in 1415 the Turks to his aid, and thus set an example which was ultimately fatal to his country.
Since their great invasion in 1398 the Turks had not molested Bosnia. Their struggle with Timour the Tartar in Asia and the confusion which followed his great victory at Angora had temporarily checked their advance in Europe, and it was not till their reorganisation under Mohammed I that they resumed their plans. They were accordingly free to accept the invitation of Ostoja and Hrvoje, who was now in opposition to the Hungarian court, and aided them to drive out the Hungarian army. The decisive battle was fought near the fortress of Doboj, the picturesque ruins of which command the junction of the rivers Bosna and Spretcha. A stratagem of the Bosniaks, who cried out at a critical moment, “The Magyars are fleeing,” won the day. But they could not rid themselves of their Turkish allies so easily. In the very next year Mohammed appointed his general Isaac governor of the castle of Vrhbosna (“the source of the Bosna”), which stood in the heart of the country, on the site of the present capital of Sarajevo, and even great Bosnian nobles were not ashamed to hold their lands by grace of the Sultan and his governor. Under Ostoja’s son, Stephen Ostojich, who succeeded as King in 1418, the country obtained a brief respite from the Turkish garrison, which quitted Vrhbosna. But three years later the restoration of Tvrtko II, after further years of exile, gave the Sultan another opportunity for intervention. For Tvrtko’s title was disputed by Ostoja’s bastard son, Radivoj, who called in the Turks to his aid, and was seen by the traveller, De la Brocquière[900] as a suppliant of the Sultan at Adrianople in 1433. Tvrtko purchased a temporary peace by the surrender of several towns to them; but the fatal secret had been divulged that the Sultan was the arbiter of Bosnia, and to him two other enemies of the King turned, the Despot of Serbia and Sandalj Hranich, a great Bosnian magnate of the house of Kosatcha, who was all-powerful in the Herzegovina, so that Chalkokondyles calls it “Sandalj’s country[901].” The two partners bought the Bosnian Kingdom from the Sultan for hard cash, and Tvrtko was once more an exile. In 1436 the Turks again occupied Vrhbosna, which from that time became a place of arms, from which they could sally forth and ravage the land, and when Tvrtko returned in the same year it was as a mere tributary of the Sultan Murad II, who received an annual sum of 25,000 ducats from his vassal, and issued charters as the sovereign of the country. Soon Murad overran Serbia, and occupied the former Bosnian towns of Zvornik and Srebrenitza, which the Serbian Despot still held, so that it seemed as if the independence of Bosnia was over. Tvrtko knew not which way to turn. He implored the Venetians, who twenty years before had taken the former Bosnian haven of Cattaro under their protection, and were now masters of nearly all Dalmatia, to take over the government of his Kingdom too. But the crafty Republic declined the dangerous honour with many complimentary phrases. With Ladislaus IV of Hungary he was more fortunate. He did not, indeed, survive to see the fulfilment of the Hungarian King’s promise, for he was murdered by his subjects in 1443. But the help of John Hunyady, the great champion of Christendom, enabled his successor to stave off for another twenty years the final blow which was to annihilate the Bosnian Kingdom.
With Tvrtko II the royal house of Kotromanich was extinct, and the magnates elected Stephen Thomas Ostojich, another bastard son of Ostoja, as their King. Ostojich, whose birth and humble marriage diminished his influence over his proud nobles, came to the conclusion that it would enhance his personal prestige, and at the same time strengthen his Kingdom against the Turks, if he embraced the Roman Catholic faith. His father and all his family had been Bogomiles, like most Bosnian magnates of that time, but Tvrtko II was a Catholic and a great patron of the Franciscans, who had suffered severely from the Turkish inroads. The conversion of Ostojich was full of momentous consequences for his Kingdom; for, although he was personally disinclined to persecute the sect to which he had belonged, and which had practically become the established church of the land, the pressure of his protector Hunyady, the Franciscans, and the Pope soon compelled him to take steps against it. He was convinced that by so doing he would drive the Bogomiles, who formed the vast majority of the people, into the arms of the Turks, and the event justified his fears. But he had little choice, for the erection of Catholic churches did not satisfy the zeal of the Franciscans. Accordingly in 1446 an assembly of prelates and barons met at Konjitza, the beautiful town on the borders of the Herzegovina, through which the traveller now passes on the railway from Sarajevo to Mostar. The document embodying the resolutions of this grand council has been preserved, and bears the name and seal of the King[902]. It provided that the Bogomiles “shall neither build new churches nor restore those that are falling into decay,” and that “the goods of the Catholic Church shall never be taken from it.” No less than 40,000 of the persecuted sect emigrated to the Herzegovina in consequence of this decree, and found there a refuge beneath the sway of the great magnate Stephen Vuktchich, of the house of Kosatcha, who had succeeded his uncle Sandalj in 1435, made himself practically independent of his liege lord of Bosnia and was at the same moment on good terms with the Turks and a strong Bogomile. Thus the old Bosnian realm was practically divided in two; Stephen Vuktchich, by posing as a defender of the national faith, received a considerable accession of subjects, and the Emperor Frederick III bestowed upon him in 1448 the title of Herzog, or Duke, of St Sava, from which his land gradually derived its present name of Herzegovina[903]. But both Bosnia and the sister land were soon to feel the hand of the Turk.
The accession of Mohammed II to the Turkish throne in 1451 was the beginning of a new era for the Balkan peoples. Since the battle of Kossovo the Sultans had been content to allow the Serbs the shadow of independence under Despots of their own, while Bosnia had bought off invasion by a tribute, more or less regularly paid, according to the vicissitudes of the Ottoman power. But the new Sultan resolved to bring the whole peninsula under his immediate sway, and lost no time in putting his plans into execution. The capture of Constantinople startled the whole of Christendom, and the great victory of Hunyady before the walls of Belgrade was small compensation for that hero’s death. There was no one left to champion the cause of the Balkan Christians, who were still occupied with their own miserable jealousies. Bosniaks and Serbs were disputing the possession of the frontier towns, which the Kings of Hungary had long ago made an apple of discord between them, and Duke Stephen of the Herzegovina was invoking the aid of the Turks at the very moment when all religious and racial enmities should have been silenced in the presence of the common foe. But it has been the misfortune of the Balkan peoples to have, like the Bourbons, learnt nothing and forgotten nothing in their centuries of suffering. They have never, save during the Balkan war of 1912-13, learnt the lesson of their mutual jealousies, and have never forgotten their historic aspirations from which those jealousies spring.
The King of Bosnia in this extremity sought aid from the west of Europe. As an obedient son of the Roman Church, he had a right to expect the help of the Pope; as a friend of the Venetians, he felt entitled to the support of the Doge. But he met with little response to his appeals. Venice, selfish as ever, was not anxious to embroil herself in Bosnian affairs, and the Pope contented himself with proclaiming a new crusade, addressing the King as the “warrior of Christ,” and promising him “a glorious victory,” in which no one else seemed desirous to share. Under these circumstances Ostojich had no alternative but to pay the tribute, which he had refused in the first flush of Hunyady’s victory at Belgrade. The one bright speck on the dark horizon was the possibility of the union of Bosnia and Serbia under one ruler by the marriage of Stephen Tomashevich, eldest son of Ostojich, with the eldest daughter of the Serbian Despot[904]. On the latter’s death in 1458, the King of Hungary acknowledged Stephen Tomashevich as Despot of all Serbia as far as the river Morava, and it seemed for the moment as if the ancient jealousies of the two neighbouring States had been finally settled and a new bulwark erected against the Turks. But the aggrandisement of the Bosnian royal family only increased its responsibilities. The important town of Semendria, which the Despot George Brankovich had founded on the Danube years before as a refuge from his enemies, and the two-and-twenty square towers of which still stand out defiant of all the ravages of Turks or Time, was strongly fortified, but its inhabitants regarded their new master, a zealous Catholic and a Hungarian nominee, as a worse foe than the Sultan himself. It is not, therefore, necessary to assume, with Pope Pius II and the King of Hungary, that Bosnian treachery betrayed them. When Mohammed II arrived at their gates they surrendered without a blow. The other Serbian towns followed the example of Semendria, and in 1459 Serbia had ceased to exist as a State and became a Pashalik of the Turkish Empire. It was the turn of Bosnia next. But Ostojich was spared the spectacle of his country’s fall. Two years later he fell in an obscure quarrel in Croatia by the hands of his brother Radivoj and his own son, Stephen Tomashevich, who succeeded to the sorry heritage of the Bosnian throne, of which he was to be the last occupant.
Stephen, son of Thomas, lost no time in seeking the aid of the Pope against the impending storm. “I was baptized as a child,” he said through the mouths of his envoys, “and have learnt to read out of Latin books. I wish, therefore, that thou wouldst send me a crown and holy bishops as a sign that thou wilt not forsake me. I pray thee also to bid the King of Hungary to go with me to the wars, for so alone can Bosnia be saved. For the Turks have built several fortresses in my kingdom and are very friendly to the peasants, to whom they promise freedom; and the limited understanding of the peasant observes not their deceit, for he believes that this freedom will last for ever. And Mohammed’s ambition knows no bounds; after me, he will attack Hungary and the Dalmatian possessions of Venice, and then march by way of Carniola and Istria into Italy, which he means to subdue; even of Rome he ofttimes speaks, and yearns to have it. But I shall be his first victim. My father foretold to thy predecessor and the Venetians the fall of Constantinople, and now I prophesy that if ye help me I shall be saved; but if not, I shall fall, and others with me.” To this eloquent appeal, which so exactly depicted the position of affairs, the Pope replied by sending his legates to the coronation—the first and last instance of a Bosnian King receiving his crown from Rome. The ceremony took place in the lovely citadel of Jajce, Hrvoje’s ancient seat, whither the new King had transferred his residence from Bobovatz for greater security. The splendour of that day and the absolute unanimity of the great nobles in support of their lord cast a final ray of light over the last page of Bosnia’s history as a Kingdom. Tomashevich made peace with all his own and his father’s enemies—with the King of Hungary, with his stepmother, Queen Catherine, and with her father, the proud Duke Stephen Vuktchich of the Herzegovina, now seriously alarmed at the advance of the Turks, who had placed a governor at Fotcha and had carved what was called the “Bosnian province” out of the district round it. The King assumed all the pompous titles of his predecessors—the sovereignty of Serbia, Dalmatia and Croatia—at a time when he could not defend his own land, and made liberal grants of privileges to Ragusa at the moment when he was imploring the Venetians to grant him a castle on the coast as a place of refuge.
The storm was not long in breaking. Mohammed II, learning that Tomashevich had promised the King of Hungary to refuse the customary tribute to the Turk, sent an envoy to demand payment. The Bosnian monarch took the envoy into his treasury and showed him the money collected for the tribute. “I do not intend,” he said, “to send the Sultan so much treasure and so rob myself of it. For should he attack me, I shall get rid of him the easier if I have money; and, if I must flee to another land, I shall live more pleasantly by means thereof[905].” So the envoy returned and told his master, and his master vowed vengeance upon the King. In the spring of 1463 he assembled a great army in Adrianople for the conquest of Bosnia. Alarmed at the result of his own defiant refusal Tomashevich sent an embassy at the eleventh hour to ask for a fifteen years’ truce. Konstantinovich, a Serbian renegade, who was an eye-witness of these events, has fortunately preserved the striking scene of Mohammed’s deceit. Concealed behind a money-chest in the Turkish treasury, he heard the Sultan’s two chief advisers decide upon the plan of campaign. “We will grant the truce,” said one of them, “and forthwith march against Bosnia, else we shall never take it, for it is mountainous, and besides, the King of Hungary and the Croats and other princes will come to its aid.” So Mohammed granted the envoys the truce which they desired, and they prepared to return and tell the good news to the King. But early next day the eavesdropper went and warned them that in the middle of the next week the Turkish army would follow on their heels. But they laughed at his tale, for they believed the word of the Sultan. Yet, sure enough, four days after their departure, Mohammed set out. One detachment of his army he sent to the Save to prevent the King of Hungary from effecting a junction with the Bosniaks, while the rest he led in person to Sjenitza, on the Bosnian frontier. His march had been so rapid and so secret that he encountered little or no resistance, until he reached the ancient castle of Bobovatz, which had stood so many a siege in Bosnia’s stormy history. The fate of this old royal residence was typical of that of the land. Its governor, Prince Radak, had been converted by force from the Bogomile faith to Catholicism. He could have defended the fortress for years even against the great Turkish army, if his heart had been in the cause. But he was, like so many of his countrymen, a Bogomile first and a Bosniak afterwards. On the third day of the siege he opened the gates to Mohammed, who found among the inmates the two envoys, whom he had so lately duped. Radak met with the fitting reward of his treachery. When he claimed from Mohammed the price for which he had stipulated, the conqueror asked him how he could keep faith with a Turk when he had betrayed his Christian master, and had him beheaded. The giant cliff of Radakovitza served as the scaffold, and still preserves the name, of the traitor.
