The Kingdom of Bosnia (Serbo-Croatian: Kraljevina Bosna / Краљевина Босна), or Bosnian Kingdom (Bosansko kraljevstvo / Босанско краљевство), was a medieval kingdom that lasted for nearly a century, from 1377 to 1463, and evolved out of the Banate of Bosnia, which itself lasted from at least 1154.
King Tvrtko I (r. 1353–91) acquired portions of western Serbia and most of the Adriatic coast south of the Neretva River. During the late part of his reign, Bosnia became one of the strongest states in the Balkan Peninsula. However, feudal fragmentation remained important in Bosnia and the Bosnian nobility held significant power, exercising it at the Stanak meetings where members deliberated on matters such as election of the new king or queen and coronations, foreign policy, sale or cession of territory, contracting and signing treaties with neighboring countries, and military issues.
The Ottoman Empire annexed portions of eastern Bosnia in the 1440s and 1450s and went on to conquer Hum, by then renamed to Herzegovina, with the last fortress, Novi, falling in December 1481. Stephen Tomašević, the last king of Bosnia, was captured by the Ottomans and killed in 1463.
The overwhelming majority of the population was rural, with few significant urban centers. Among the more notable towns were Doboj, Jajce, Srebrenik, Srebrenica, Tešanj, and Podvisoki. Mining, especially for silver, was a major source of income for Bosnian kings.
Background
The Banate of Bosnia was a medieval state comprising, at its peak, most of what is today Bosnia and Herzegovina, as well as parts of Dalmatia (in Croatia), Serbia, and Montenegro. Although nominally belonging to the Kingdom of Hungary crown lands, it was a de facto independent state. After the reign of Ban Kulin, rulers of Bosnia enjoyed virtual independence from Hungary, and although they formally held a vassal position for much of this time, in reality they managed to maintain independent functions and even expand their rule in Serbia, Croatia, and Dalmatia.
The Banate of Bosnia existed until 1377, when it was elevated into a kingdom through the Serbian crown coronation of Tvrtko I, held at the Serbian Orthodox Mileševa Monastery before the relics of Saint Sava of Serbia, following the death of the last Serbian Emperor from the Nemanjić dynasty, Stefan Uroš V, who died childless and without an heir in 1371.
Coronation of Tvrtko
Tvrtko had the strongest claim to the royal title at that time, and even if he had no practical means to rule Serbia, it allowed him to elevate Bosnia to a kingdom, as this would imply more formal independence. Tvrtko thus proclaimed himself the first King of Bosnia, claiming full legitimacy as the crown he took was sent from Pope Honorius III to Stefan the First-Crowned in 1217. A Serbian logothete named Blagoje, having found refuge at Tvrtko's court, attributed to Tvrtko the right to a "double crown": one for Bosnia, and the other for the Serbian lands of his Nemanjić ancestors. He was also King of Serbia, and in that way, legal basis for crowning was achieved, which was promoted even by his formal sovereign Louis I. Tvrtko's title as a king was also approved by Louis's successor, and Tvrtko's cousin, Mary, Queen of Hungary. Venice and Ragusa consistently referred to Tvrtko as King of Rascia, Ragusa even complaining, in 1378, about Tvrtko's preoccupation with his new kingdom. Tvrtko's coronation as King of Bosnia and Serbia was held in the fall of 1377 (probably 26 October, the feast day of Saint Demetrius), and marked a significant event of Bosnian medieval history, although contemporary sources about the coronation are very rare. The Royal Charter issued to the Ragusan commune on 10 April 1378 stands as one of the key sources for understanding the position of medieval Bosnian banate and its transformation to the kingdom, as well as information about economic activity between Bosnia and Ragusa, and proof of Bosnian independence.
Stanak
Feudal fragmentation remained important feature in Bosnia and the Bosnian nobility held significant power, exercising it at the Stanak meetings. The Stanak is the most common name used to refer to the assembly of nobility in medieval Bosnia, and it is first attested in the charter of Tvrtko I in 1354. Its influence peaked between the 1390s and the 1420s. The existence of the stanak proved a unity and feeling of belonging to a Bosnian identity and integrity, but also it illustrated weakness of the monarch and decentralization of the state.
The right to take part in the sessions of the stanak was enjoyed by every Bosnian knez, from magnates to petty lords, collectively known as vlastela, but the ultimate authority belonged to the highest nobility. The stanak was convoked when required, usually by the ruler, who presided over it and led its sessions. If male, his wife was allowed to attend, but his children were not. The Bosnian Church clergy, not belonging to the vlastela, were also barred, but influenced decision-making in the stanak through the great lords associated with them. The magnates of the country convoked the stanak themselves when the country experienced greater domestic issues, such as succession crisis or deposition of the ruler, domestic conflicts or wars. It normally took place wherever the monarch held court: in Mile, Milodraž, Bobovac, Kraljeva Sutjeska and Jajce.
The Stanak enjoyed power and authority on all matters, including election of the new king or queen and coronation, foreign policy, sale or cession of territory, contracting and signing treaties with neighboring countries, and military issues. Charters issued by monarchs reflected the decisions made by the stanak; as the royal power weakened, that of stanak increased.
International recognition
Hungarian rulers perceived Bosnia as a country under their sovereignty during medieval time. Bosnian rulers acted completely independently in carrying out state and diplomatic affairs, governing the judicial system, granting towns and estates, minting coins, exploiting natural resources, and making trading agreements with other countries and independent cities.
As a main trading partner of the Bosnian state, Ragusa referred to the Bosnian Kingdom as a separate state ("rusag"), for example in a charter issued to Sandalj Hranić in November 1405, where they articulated that Ragusan merchants would be safe across the "Bosnian rusag", or 1451, during the war with Stjepan Vukčić, as a "Holy Kingdom". Ragusans also paid Saint Demetrius an income of 2000 Ragusan perpera. Ladislaus of Naples acknowledged the territories of the kingdom on 26 August 1406 at the request of Tvrtko II.
History
Tvrtko's I ascension and reign
Bosnia reached its peak under Tvrtko I, a member of the Kotromanić dynasty, who came to power in 1353. In 1372, Tvrtko formed an alliance with Prince Lazar Hrebeljanović, one of the regional lords in the territory of the disintegrated Serbian Empire. The next year, Tvrtko and Lazar attacked the domain of Nikola Altomanović, the most powerful Serbian noble at the time. After defeating Altomanović, they divided his lands, except for his littoral districts of Dračevica, Konavle, and Trebinje, which were seized by Đurađ I Balšić, the Lord of Zeta. Tvrtko received parts of Zahumlje, the upper reaches of the Drina and Lim rivers, and the districts of Onogošt and Gacko. This acquisition included the important Serbian Orthodox monastery of Mileševa, which held the relics of Saint Sava, the first Serbian Archbishop.
In 1377, Tvrtko took the littoral districts from Balšić. That year, on 26 October, he was crowned King of "The Serbs, Bosnia, the Primorje (Seaside), and the western lands". The acquisition of Serbian territory, including the important Monastery of Mileševa, combined with the fact that Tvrtko's grandmother had been a member of the Nemanjić dynasty, prompted Tvrtko into having himself crowned King of Serbia, thus asserting his pretensions to the Serbian throne. This was made possible by the royal Nemanjić line having died out with Uroš in 1371. The crown was sent to him by Hungarian king Louis of Anjou. According to a plurality of recent works from scholars like Čošković, Anđelić, Lovrenović, and Filipović, the ceremony itself was conducted in Mile near Visoko in the church that was built during Stephen II Kotromanić's reign, where he was also buried alongside his uncle Stjepan II. In contrast, some earlier historiographers, mostly represented by western scholars, consider that he was crowned in the Orthodox Monastery of Mileševa by the Metropolitan of Mileševa.
After the defeat of Altomanović, Lazar was the most powerful lord on the territory of the former Serbian Empire. He wanted to reunite the Serbian state, and the Serbian Orthodox Church saw him as the best suited to succeed the Nemanjić dynasty. The Church, which was the strongest cohesive force among the Serbs at the time, did not support Tvrtko's aspirations in this regard.
By 1390, Tvrtko had expanded his realm to include a part of Croatia and Dalmatia, and expanded his title to "King of The Serbs, Bosnia, Dalmatia, Croatia and the Littoral". Tvrtko's full title listed subject peoples and geographical dependencies, following the Byzantine norm. At the peak of his power, he was "King of Bosnia, Serbia, Croatia, Hum, Usora, Soli, Dalmatia, and Donji Kraji".
In the last months of his reign, Tvrtko devoted himself to solidifying his position in Dalmatia and to plans for taking Zadar, the only Dalmatian city that had evaded his rule. He offered an extensive alliance to Venice, but it did not suit the republic's interests. Meanwhile, Tvrtko was also fostering relations with Albert III, Duke of Austria. By the late summer of 1390, a marriage was expected to be contracted between the recently widowed King and a member of the Austrian ruling family, the Habsburgs. The Hungarian kingdom remained the focus of Tvrtko's foreign policy, however. Although they did not recognize each other as kings, Tvrtko and Hungarian King Sigismund started negotiating a peace in September. Sigismund was in the weaker position and likely ready to make concessions to Tvrtko when his ambassadors arrived at Tvrtko's court in January 1391. The negotiations were probably never concluded, as Tvrtko died on 10 March.
Death of Tvrtko I and decline
While Bosnia retained its standing among neighboring states in the immediate aftermath of Tvrtko's death, during Dabiša's reign conditions within the state started deteriorating. He successfully resisted his sovereigns from Hungary, Naples, and even Ottoman Turks. In the first years of his reign, Dabiša successfully maintained the integrity of the Kingdom.
The latter part of his reign, however, saw the ascent of magnates and considerable loss of territories and influence. The nobility grew stronger and for the first time acted independently of the king, starting with the Zachlumian Sanković noble family. Dabiša curbed the Sanković power, but the trend was irreversible and eventually led to the weakening of the royal authority. Hrvoje Vukčić Hrvatinić, the kingdom's leading magnate, came into agreement with Sigismund and Mary but remained loyal to Dabiša. By June 1394, Dabiša was in open conflict with John Horvat, a fervent supporter of Ladislaus and enemy of Sigismund. He ordered that men from his islands of Brač, Hvar, and Korčula assist in the siege of Omiš, a city ruled by Horvat. Sigismund, who had been amassing an army since April, took advantage of the discord.
The Battle of Dobor saw Horvat's defeat and execution as well as the destruction of the eponymous town on the river Bosna by Sigismund's troops. Soon thereafter Dabiša submitted to Sigismund and resigned Croatia and Dalmatia to the Hungarian king and, with the agreement of his vassals, recognized him as his feudal overlord as well as heir designate to the Bosnian throne. It is not clear what prompted Dabiša to agree to such harsh terms. In return, as evident from a treaty issued in July 1394, Sigismund included Dabiša among the highest ranking Hungarian officials and named him ispán (count) of Somogy.
Despite an auspicious start, Dabiša's reign ended with the kingdom displaying the first signs of decay. Much of Tvrtko's extraordinary legacy was lost in the summer of 1394, and the state resumed its previous boundaries. Dabiša left the state more dependent on Hungarian kings than ever before, and the kingdom's influence in the Balkans waned.
