Ottoman Empire
Bayezid I
In 1396 the Ottoman Empire was ruled by Sultan Bayezid I, who had consolidated Ottoman control over most of Bulgaria, including Tarnovo since 1393, and parts of Serbia following the Battle of Kosovo in 1389. The empire exerted influence over Byzantine territories, manipulating their internal politics, notably supporting John VII's brief seizure of Constantinople in 1390. The Ottomans were the dominant power in the Balkans, with Dobruja contested but under Ottoman influence.
The Ottoman Empire had conquered most of Bulgaria by 1393, including Tarnovo, and had placed Bulgaria under direct Ottoman administration by 1396. The Bulgarian ruler Ivan Shishman was executed in 1395, and the Ottomans controlled Bulgarian lands except for Vidin. The Ottomans also had influence in the contested Dobruja region.
Serbia
Stefan Lazarević
In 1396 Serbia was ruled by Stefan Lazarević as a despot, controlling fragmented principalities including Kosovo and parts of western Macedonia. The state was weakened following the 1389 Battle of Kosovo against the Ottomans, with nobles like Vuk Branković exercising considerable autonomy. Serbia remained a significant regional power but faced increasing Ottoman pressure.
Serbia shared a border with Bulgaria and had complex relations including rivalry over Macedonian territories. Serbian ruler Stefan Dusan had married a sister of Bulgarian Tsar John Alexander, linking the dynasties. By 1396, Serbian nobles minted their own coins and controlled regions bordering Bulgaria, reflecting fragmented authority but ongoing interactions.
Zeta
Đurađ II Balšić
In 1396 Zeta was ruled by Đurađ II Balšić as a semi-independent principality under the influence of the Serbian nobility. The region was marked by internal noble conflicts and external pressures from neighboring powers, including the rising Ottoman Empire. Zeta's coastal towns such as Bar and Ulcinj were strategically important and contested by Venice and local noble families.
Despotate of Epirus
Esau
In 1396 the Despotate of Epirus was ruled by Esau, who controlled the Jannina region and contested Arta. The state was fragmented, facing ongoing conflicts with Albanian clans and under increasing Ottoman influence. Esau allied with the caesar of Thessaly and the Ottomans to defeat Albanian tribes and secured peace through marriage to John Spata's daughter, positioning Epirus as a contested borderland among regional powers.
In 1396 Epirus shared rivalry and conflict with Albanian clans near its borders, some of whom had ties to regions adjacent to Bulgaria. The alliance of Esau with the Ottomans and Thessalian rulers indirectly affected the balance of power in the Balkans, where Bulgaria was also contending with Ottoman expansion and regional instability.
Byzantine Empire
Manuel II Palaiologos
In 1396 the Byzantine Empire was ruled by Emperor Manuel II Palaiologos. The empire was a diminished state, holding Constantinople (contested), Thessaly, and parts of Thrace, while key Aegean islands were under Venetian control. Internal dynastic struggles and Ottoman vassalage weakened the empire, which faced pressure from the rising Ottoman power and rival claimants to the throne.
The Byzantine Empire shared a complex relationship with Bulgaria in 1396, marked by prior conflicts and shifting alliances. The empire had lost Black Sea ports to Bulgaria in earlier decades but regained some territories. By this year, Bulgaria was under Ottoman pressure, and the Byzantine emperor was an Ottoman vassal, reflecting the intertwined fates of the two states.
Duchy of Athens
Acciaioli
In 1396 the Duchy of Athens was ruled by Donato Acciaioli, who had inherited the duchy from his brother Nerio I Acciaioli in 1394. The duchy was weakened by internal debts and external threats, notably from the Turks who besieged the Acropolis. Donato, unable to resist alone, sought Venetian assistance, leading to a brief Venetian protectorate over Athens. The duchy was a Latin feudal state centered in Attica with its capital traditionally at Thebes, and it was surrounded by rising Ottoman power and fragmented Frankish principalities.
Venice
Doge of Venice
In 1396 the Republic of Venice was ruled by the Doge of Venice and controlled key maritime territories in the Aegean, including the entire island of Euboea (Negroponte) and various Aegean islands and coastal forts. Venice had consolidated its control over Euboea by 1390 after purchasing lands from the heirs of the triarchs and distributing fiefs to Venetian candidates, strengthening its position in the region. The Republic remained a significant maritime power in the eastern Mediterranean, maintaining fortified holdings and influence among neighboring states.
Venice had no direct political interests in Bulgaria in 1396 and maintained primarily commercial relations, satisfied by regulated conditions for grain trade. There was no open conflict or alliance, but Venice's maritime holdings in the Aegean were strategically important near Bulgarian and Ottoman territories.
Wallachia
Mircea the Elder
In 1396 Wallachia was ruled by Mircea the Elder as an independent principality. The state was engaged in military conflicts over Dobruja, a contested region, and had recently suffered defeat by the Ottomans. Wallachia remained a significant regional power resisting Ottoman expansion alongside its neighbors.
In 1396 Wallachia, under Mircea the Elder, was in conflict with the Ottomans who had taken Dobruja. Mircea styled himself lord of Dristar and despot of Dobrujan lands after a raid into Dobruja but was defeated by the Turks in 1391. Wallachia shared a border with Bulgaria and was involved in regional military struggles linked to Bulgarian territories.
Hungary
Sigismund
In 1396 the Kingdom of Hungary was ruled by King Sigismund. The kingdom was a significant regional power engaged in ongoing conflicts and rivalries with neighboring states, including Bulgaria and the Ottoman Empire. Hungary maintained claims over Bulgarian territories and was involved in military campaigns and political maneuvers to assert influence in the Balkans.
Hungary in 1396 was a rival to Bulgaria, maintaining claims over Bulgarian lands and exerting pressure on the Vidin region, which was one of the last Bulgarian territories not fully conquered by the Ottomans. King Sigismund supported local rulers and military actions against Ottoman advances and Bulgarian vassalage to the Sultan.
Kingdom of Bosnia
In 1396 the Kingdom of Bosnia was ruled by King Stephen Dabisa. The kingdom was an independent polity situated between the expanding Ottoman Empire and the Kingdom of Hungary. Bosnia maintained its internal noble autonomy, with powerful local lords, but under a recognized royal authority. It was involved in regional conflicts and alliances, notably participating in resistance against Ottoman expansion alongside Serbian forces in the preceding decade.
Bosnia shared a border with the Bulgarian lands and had allied with Serbian forces against the Ottomans, who had subdued much of Bulgaria by 1396. The Bosnian kingdom was indirectly involved in the regional struggle that affected Bulgaria, as the Ottomans consolidated control over Bulgarian territories while Bosnia remained independent but threatened.
Knights Hospitaller
In 1396 the Knights Hospitaller were a military order holding several island territories in the eastern Mediterranean. Their power was regional and maritime, and they were involved in conflicts and alliances with neighboring states and principalities. The order was led by Grand Master John Fernandez de Heredia since 1377, who had directed military campaigns in Epirus and the Morea region. The Knights maintained a strategic presence but faced increasing pressure from Ottoman expansion and local rivalries.
Genoa
In 1396, the Republic of Genoa maintained significant commercial and territorial interests in the Black Sea region, including holdings in Dobruja. Genoa had concluded treaties with local rulers such as Ivanko, the successor of Despot Dobrotica, securing broad privileges and influence. The Republic was engaged in ongoing rivalry with Venice and conflicts with regional powers, including the Dobrujan despotate, reflecting its strategic role in Black Sea trade and politics.
Genoa had strained relations with Bulgaria due to conflicts involving Genoese merchants in Bulgarian-controlled territories. Despite diplomatic efforts, Genoa failed to obtain redress for damages suffered by its traders. The Republic's rivalry with Venice, which had closer ties to Bulgaria, further complicated relations.
