Stephen Dabiša was as a member of the Kotromanić dynasty who reigned as King of Bosnia from March 1391 until his death. Elected to succeed the first king, Tvrtko I, Dabiša at first maintained the integrity of the Kingdom of Bosnia. He successfully resisted Hungary, Naples, and even Ottoman Turks. The latter part of his reign, however, saw the ascent of magnates and considerable loss of Bosnia's territory and influence.
Stephen Tvrtko I was the first king of Bosnia. A member of the House of Kotromanić, he succeeded his uncle Stephen II as the ban of Bosnia in 1353. As he was a minor at the time, Tvrtko's father, Vladislav, briefly ruled as regent, followed by Tvrtko's mother, Jelena. Early in his personal rule, Tvrtko quarrelled with his country's Roman Catholic clergy but later enjoyed cordial relations with all the religious communities in his realm. After initial difficulties—the loss of large parts of Bosnia to his overlord, King Louis I of Hungary, and being briefly deposed by his magnates—Tvrtko's power grew considerably. He conquered some remnants of the neighbouring Serbian Empire in 1373, after the death of its last ruler and his distant relative, Uroš the Weak. In 1377, he had himself crowned king of Bosnia and Serbia, claiming to be the heir of Serbia's extinct Nemanjić dynasty.
The House of Kotromanić was a late medieval Bosnian noble and later royal dynasty. Rising to power in the middle of the 13th century as bans of Bosnia, with control over little more than the valley of the eponymous river, the Kotromanić rulers expanded their realm through a series of conquests to include nearly all of modern-day Bosnia and Herzegovina, large parts of modern-day Croatia and parts of modern-day Serbia and Montenegro, with Tvrtko I eventually establishing the Kingdom of Bosnia in 1377. The Kotromanić intermarried with several southeastern and central European royal houses. The last sovereign, Stephen Tomašević, ruled briefly as Despot of Serbia in 1459 and as King of Bosnia between 1461 and 1463, before losing both countries – and his head – to the Ottoman Turks.
Hrvoje Vukčić Hrvatinić was a medieval Bosnian nobleman and magnate, Grand Duke of Bosnia, Knez of Donji Kraji, and Duke of Split. He was the most prominent member of the Hrvatinić noble family, and one of the major feudal lords in Kingdom of Bosnia. He was Grand Duke of Bosnia under three Bosnian kings: King Tvrtko I, King Stephen Dabiša and King Stephen Ostoja. In 1403, and after Tvrtko I's death, Ladislaus of Naples named him his deputy for Dalmatia, and bestowed him with a title Duke of Split, later Herzog of Split. He played a crucial role in the dynastic struggles between the Anjou and Luxembourg claimants to the Hungarian-Croatian throne at the end of the 14th century, as well as in the emergence of the Bosnian Kingdom as a regional power during the same period.
Vladislav of Bosnia was a member of the House of Kotromanić who effectively ruled the Banate of Bosnia from September 1353 to his death.
Stephen Ostoja was King of Bosnia from 1398 to 1404 and from 1409 to 1418.
Stephen Thomas, a member of the House of Kotromanić, reigned from 1443 until his death as the penultimate king of Bosnia.
Stephen Tvrtko II, also known as Tvrtko Tvrtković, was a member of the House of Kotromanić who reigned as King of Bosnia from 1404 to 1409 and again from 1420 to his death.
The area of today's Visoko is considered to be a nucleus from where Bosnian statehood was developed in 10th century. The expanded valley of the river Bosna around today's Visoko was the biggest agriculture area in central Bosnia, so fertile ground around Visoko was ideal for development of early political center of Bosnian nobility.
Jelena Šubić was a member of the Bribir branch of the Croatian Šubić noble family who ruled the Banate of Bosnia as regent from 1354 until 1357 during the minority of her son Tvrtko I of Bosnia.
Radič Sanković was a powerful Bosnian nobleman and magnate, with a title of vojvoda (duke) in the Kingdom of Bosnia during the reign of Stephen Dabiša (1391-1395) and Queen Helen (1395-1398). He allied himself with usurper Stephen Ostoja (1398-1404) during the civil wars, until his death in 1404. With the title of vojvoda, he held territories in present-day Herzegovina, including Župa Valley with Glavatičevo as its center, Nevesinje, parts of Popovo Polje and most of Konavle.
Sandalj Hranić Kosača was a powerful Bosnian nobleman whose primary possessions consisted of Hum, land areas between Adriatic coast, the Neretva and the Drina rivers in Bosnia, and served the court as the Grand Duke of Bosnia sometime between 1392 and his death in 1435, although the first mention as a Grand Duke in sources comes from 16 June 1404. He was married three times, but had no children. After his death, he was succeeded by his nephew Stjepan Vukčić Kosača.
Stjepan Vukčić Kosača (1404–1466) was a powerful Bosnian nobleman who was politically active from 1435 to 1465; the last three decades of Bosnian medieval history. During this period, three kings acceded to the Bosnian throne: Tvrtko II, Thomas (Tomaš), Stephen Tomašević (Stjepan Tomašević) and anti-king Radivoj—the older brother of King Thomas—before the country was conquered by the Ottomans.
The Kingdom of Bosnia, or Bosnian Kingdom, 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 since at least 1154.
Stephen Ostojić was King of Bosnia from the death of his father Ostoja in 1418 until his deposition by the nobility in 1420.
Pavle Radinović, sometimes Radenović,, was one of the most powerful Bosnian nobleman under Tvrtko I, Dabiša, Jelena Gruba, Ostoja, Tvrtko II and Ostoja again. He was a knez and the head of Radinović-Pavlović noble family, a powerful magnate clan whose initially possessions spread from central to eastern Bosnia, gravitating around the Prača - Miljacka river axis, between the Krivaja Drina and the Upper Bosna rivers, with the seat in Borač and Pavlovac between Prača and Rogatica, and also held mines in Olovo and Fojnica.
Vukosav Nikolić was mid-ranking Bosnian nobleman and a vassal to Kosača-Vukčić family under Sandalj Hranić, who served the Kingdom of Bosnia during the reign of his relative Jelena Gruba and Stephen Ostoja ,. He was the lord of Neum, the Popovo field, and the Lower Neretva region. He fell in battle during the Bosnian-Ragusan War (1403).
The Humska Zemlja, also Hum, is a historical zemlja that arose in the Middle Ages as well-defined administrative unit of medieval Bosnia ruled by the Kosača dynasty. It included most of today's Herzegovina, in Bosansko Primorje including Konavle, territories on the south of Dalmatia between Omiš and Neretva Delta, in Boka Kotorska and south to Budva. The name for this zemlja derived from the earlier name for the region, Zahumlje. The seat of Kosače family was in the town and fortress of Blagaj and during the winter seasons, Novi.
Radoslav Pavlović, sometimes spelled Radislav, Radisav or Radosav, was a Bosnian nobleman of the noble family Pavlović-Radinović. He inherited title of knez from his father Pavle Radinović upon his father death, while his older brother Petar (1415–1420), being the first in order of precedence, was bestowed a title of duke by the Bosnian throne. He and his brother also inherited their father's estates in the eastern parts of the Kingdom of Bosnia. After the murder of his father Pavle Radinović on Parena Poljana, near Sutjeska and Bobovac, in 1415 by the hand of Grand Duke of Bosnia, Sandalj Hranić (1392–1435), Radosav together with his older brother Peter, started a war against Sandalj Hranić and his Kosača clan, as those responsible for the murder. After the death of his older brother Petar in the conflict with the Ottomans in 1420, Radosav assumed leadership over the Pavlović's clan and took over the title of duke, and around 1421 he was bestowed a title of Grand Duke of Bosnia by the throne. He ended the conflicts with the Kosača and sealed the peace with a marriage with the daughter of Vukac Hranić, princess Teodora, the sister of the future Kosača's clan chieftain, Stjepan Vukčić (1435–1466), with whom he had three sons. In 1426, he sold his part of Konavle to the Republic of Ragusa for 18,000 perpers, but in 1430 he started the so-called First Konavle War over the sold territories, which ended in 1432 with the recognition of the situation from the beginning of the conflict. In 1435, after the death of Duke Sandalj Hranić, he tried to take advantage of the new situation, but in a conflict with his wife's brother Stjepan, he eventually lost the southern parts of his zemlja around Trebinje. He died in 1441, and was succeeded by his son Ivaniš Radoslavić Pavlović (1441–1450).
Petar I Pavlović was a knez, and then a Grand Duke of Bosnia, from the noble family of Pavlović, which had its possessions in the eastern parts of the Kingdom of Bosnia. After the murder of his father Pavle Radinović on Parena Poljana near royal court in Sutjeska and below a Bobovac in 1415, after the stanak at which whole Pavlović family was present at, Petar took over the leadership of the Pavlovići and with his younger brother Knez Radosav (1420–1441) started a war against Sandalj Hranić (1392–1435) and Kosača klan. In that conflict, he relied on the help of the Ottomans, whose help he paid for by recognizing vassal relations to the sultan, which also resulted in successful campaigns against Sandalj, who was completely suppressed. However, the Ottomans changed sides and arrived in the Kingdom of Bosnia in 1420 as Sandalj's allies against Pavlović. In the conflict with them, Petar himself was killed, and his younger brother Radosav succeeds him as the leader of Pavlović and the Grand Duke of Bosnia.
