Family Tree of the Second Bulgarian Empire
23 reigning rulers across four dynasties — with their consorts, kin and the family's Byzantine branch
The Second Bulgarian Empire (1185–1396) was ruled by four successive dynasties — the Asen, Terter, Smilets and Shishman houses — from the uprising of the brothers Peter and Asen against Byzantium to the fall of Tarnovo to the Ottomans. This family tree charts every tsar and their relatives across those two centuries, together with the Asens in Byzantium: the descendants of Ivan Asen III, who lived on in Constantinople as the noble Asanes family.

Isaac Asen was one of the five sons of Tsar Ivan Asen III (John III Asen) and Irene Palaiologina. At the coronation of Emperor John V Palaiologos (1341) he was raised to the highest rank of panhypersebastos.
Isaac became an influential figure in the civil war against John Kantakouzenos. After the murder of the grand duke Alexios Apokaukos (11 July 1345), he — together with Kinnamos the mystikos and Patriarch John Kalekas — was entrusted with supreme power in the rebellious Constantinople; scholars describe him as "prime minister" (mesazon) or "director of state affairs."
Isaac Asen was married twice. His first wife, Theodora Arachantloun, inherited the rights over the monastery of the Virgin founded by Maria Palaiologina; after her death Isaac used the property for the needs of his children, which led to a lawsuit in 1351. From his marriages he had the sons grand primikerios Andronikos, Andrey and Michael, and the daughter Irene Asenina Philanthropene. In 1346 he commissioned the copying of a tetraevangelion that survives to this day.
