1185–1396
The Second Bulgarian Empire
In 1185 the brothers Peter and Asen rose against Byzantium, and Bulgaria was independent again. For the next two centuries it was ruled from Tarnovo by tsars of four successive dynasties, and under Ivan Asen II its power reached from the Black Sea to the Adriatic. It ended with the Ottoman capture of Tarnovo in 1393 and of Vidin in 1396.
This site gathers what we know about that state: its rulers and their families, battles, coins, charters, churches and daily life, drawn from the work of Bulgarian historians and from the medieval sources themselves.

Kaliman Asen II
Tsar · 1256–1256
Kaliman Asen II was a Bulgarian tsar of the Asen dynasty whose entire known reign fell in 1256. He belonged to a collateral male branch of the ruling house: his father was the sebastokrator Alexander, younger brother of Tsar Ivan II Asen. Since Ivan II Asen was a son of Ivan I Asen, Kaliman was a grandson of one of the founders of the restored Bulgarian Empire and a first cousin of his predecessor, Michael II Asen. This ancestry gave him a dynastic basis for claiming the crown, but the manner in which he acquired it—by killing Michael and seizing power—made his accession an act of violent usurpation as well as a contest between branches of the same family.
Kaliman's lineage connected him directly to the political tradition inaugurated at Tarnovo in 1186 by Ivan I Asen and Theodore-Peter. That tradition treated imperial authority as, in an important sense, the patrimony of the ruling family. The historical discussion quoted in the dossier recalls Michael Psellos's generalization that the Bulgarians chose leaders from the imperial race, while later formulations allowed the throne to pass to a ruler's son, brother, or other relative. Such principles did not establish an unambiguous order of primogeniture: they could legitimate several related claimants at once. Kaliman's brief career illustrates the resulting tension between membership in the imperial house, actual possession of the capital and crown, and acceptance by the political elite.

Theodore Svetoslav — Partial Recovery (1300–1330)
The chapter follows Theodore Svetoslav’s violent accession in 1300 and his subsequent restoration of Bulgarian authority through internal consolidation, frontier bargaining, and a decisive series of wars against Byzantium. That recovery endured into the reign of Michael Shishman, but the era ended in 1330 with the Bulgarian defeat at Velbuzhd, which reopened dynastic instability.

Vidin Tsardom — Last Resistance (1396–1422)
The chapter follows Vidin as the last Bulgarian stronghold on the Danube, from its final courtly gestures before conquest to its fall after the crusader defeat at Nicopolis in 1396. Thereafter the Vidin line survives mainly through Constantine's exile, a brief revival of hope during the Ottoman interregnum, the uprising of Constantine and Fruzhin, and finally Constantine's death in 1422.

Boril — Internal Struggles (1207–1218)
Boril seized the Bulgarian throne in 1207 after Kaloyan’s death, but his reign was immediately undermined by dynastic rivalry, regional defections, and repeated defeats against the Latins and their Balkan allies. He tried to shore up authority through warfare, alliance-making, and the anti-Bogomil council of 1211, yet the kingdom steadily fragmented until John Asen II returned in 1218 and overthrew him.

Ivan Alexander — Cultural Flourishing (1330–1355)
Ivan Alexander’s reign began in 1331 with the restoration of native Asenid rule after the collapse of the Serbian-backed regime, and it was immediately tested by revolt, Byzantine pressure, and shifting Balkan politics. He secured the throne through victory and repression, then presided over a period of notable cultural and ecclesiastical flourishing even as regional lordships, heresy, and the Ottoman advance began to weaken the kingdom’s unity.

The Battle of Nicopolis (25 September 1396) and the fate of Tsar Ivan Sratsimir
Pavlov follows King Sigismund's crusade from Buda to the rout at Nicopolis and what it meant for the Vidin tsardom. His main argument is that Ivan Sratsimir was not taken captive straight after the battle but during a later campaign of Bayezid against Hungary in 1397/1398, the date given by the Bulgarian Anonymous Chronicle and the Serbian annals.

The historic Bulgarian north-west, 12th–15th centuries
A survey of the long contest between Bulgaria, Hungary and Serbia for Belgrade, Braničevo and the Morava valley, from Kaloyan and Ivan Asen II to Mihail III Shishman and Konstantin II Asen's Vidin tsardom. It closes with the little-known Bulgarian fortresses and monasteries of today's eastern Serbia.

The noblewomen of the Bulgarian Morava valley in the 14th century
On the donor portraits in the churches of Staničenje and Donja Kamenica: a boyar family related to the Shishmanids, the young Areta with her unusual name, and a despotissa some identify as the young Anna Neda. Their dress and inscriptions show how closely the Vidin region was tied to Hungary and the Catholic world.

Noble ladies of medieval Dobrudzha and the Black Sea coast in the 14th century
Pavlov looks at the mysterious Sevina of the Emine monastery charter, the despotissa Keratsa Petritsa (Ivan Alexander's mother, called a Catholic in a papal letter) and the women of Despot Dobrotitsa's family. He suggests Ivan Alexander spent his youth in Varna and the Karvuna land, and presents new finds from Kaliakra and Drastar.
