This is a family tree of all the Eastern Roman Emperors who ruled in Constantinople. Most of the Eastern emperors were related in some form to their predecessors, sometimes by direct descent or by marriage. From the Doukid dynasty (1059) onwards all emperors are related to the same family.
Dynasty names are given in capitals so that they can be picked out from the interweaving trees. Junior co-emperors who never exercised real power are shown in a smaller font to distinguish them from the reigning emperor.
This is a simplified family tree centered solely around the Eastern Empire, for a fuller list that includes both Eastern and Western emperors, see Family tree of Roman emperors

Alexios I Komnenos, Latinized Alexius I Comnenus, was Byzantine emperor from 1081 to 1118. Although he was not the first emperor of the Komnenian dynasty, it was during his reign that the Komnenos family came to full power and initiated a hereditary succession to the throne. Inheriting a collapsing empire and faced with constant warfare during his reign against both the Seljuq Turks in Asia Minor and the Normans in the western Balkans, Alexios was able to curb the Byzantine decline and begin the military, financial, and territorial recovery known as the Komnenian restoration. His appeals to Western Europe for help against the Turks was the catalyst that sparked the First Crusade.
Isaac II Angelos or Angelus was Byzantine Emperor from 1185 to 1195, and co-Emperor with his son Alexios IV Angelos from 1203 to 1204. In a 1185 revolt against the Emperor Andronikos Komnenos, Isaac seized power and rose to the Byzantine throne, establishing the Angelos family as the new imperial dynasty.
Isaac I Komnenos or Comnenus was Byzantine emperor from 1057 to 1059, the first reigning member of the Komnenian dynasty.
Michael VII Doukas or Ducas, nicknamed Parapinakes, was the senior Byzantine emperor from 1071 to 1078. He was known as incompetent as an emperor and reliant on court officials, especially of his finance minister Nikephoritzes, who increased taxation and luxury spending while not properly financing their army. Under his reign, Bari was lost and his empire faced open revolt in the Balkans. Along with the advancing Seljuk Turks in the eastern front, Michael also had to contend with his mercenaries openly turning against the empire. Michael stepped down as emperor in 1078 and later retired to a monastery.

The Despotate of Epirus was one of the Greek successor states of the Byzantine Empire established in the aftermath of the Fourth Crusade in 1204 by a branch of the Angelos dynasty. It claimed to be the legitimate successor of the Byzantine Empire, along with the Empire of Nicaea and the Empire of Trebizond, its rulers briefly proclaiming themselves as Emperors in 1227–1242. The term "Despotate of Epirus" is, like "Byzantine Empire" itself, a modern historiographic convention and not a name in use at the time.
The Empire of Trebizond, or Trapezuntine Empire, was a successor state of the Byzantine Empire that existed during the 13th through to the 15th century. The empire consisted of the Pontus, or far northeastern corner of Anatolia, and portions of southern Crimea.
The House of Palaiologos, also found in English-language literature as Palaeologus or Palaeologue, was a Byzantine Greek noble family that rose to power and produced the last and longest-ruling dynasty in the history of the Byzantine Empire. Their rule as Emperors and Autocrats of the Romans lasted almost two hundred years, from 1259 to the Fall of Constantinople in 1453.
The House of Komnenos, Latinized as Comnenus, was a Byzantine Greek noble family who ruled the Byzantine Empire in the 11th and 12th centuries. The first reigning member, Isaac I Komnenos, ruled from 1057 to 1059. The family returned to power under Alexios I Komnenos in 1081 who established their rule for the following 104 years until it ended with Andronikos I Komnenos in 1185. In the 13th century, they founded and ruled the Empire of Trebizond, a Byzantine rump state from 1204 to 1461. At that time, they were commonly referred to as Grand Komnenoi, a style that was officially adopted and used by George Komnenos and his successors. Through intermarriages with other noble families, notably the Doukas, Angelos, and Palaiologos, the Komnenos name appears among most of the major noble houses of the late Byzantine world.
The despot of Epirus was the ruler of the Despotate of Epirus, one of the successor states of the Byzantine Empire in the aftermath of the Fourth Crusade. The name "Despotate of Epirus" and the title "despot of Epirus" are modern historiographical names, and were not in use by the despots themselves. In the Byzantine Empire, the title of despot was a prestigious court title and did not designate rule over some specific territory. Though several of the early Greek rulers of the Epirote realm did use the title of despot, it was never in reference to the lands they governed, but instead in reference to their position in the imperial hierarchy.
The House of Doukas, Latinized as Ducas, was a Byzantine Greek noble family, whose branches provided several notable generals and rulers to the Byzantine Empire in the 9th–11th centuries. A maternally-descended line, the Komnenodoukai, founded the Despotate of Epirus in the 13th century, with another branch ruling over Thessaly.
The House of Angelos, Latinised as Angelus, was a Byzantine Greek noble family that produced several Emperors and other prominent nobles during the middle and late Byzantine Empire. The family rose to prominence through the marriage of its founder, Constantine Angelos, with Theodora Komnene, the youngest daughter of Emperor Alexios I Komnenos. As imperial relatives, the Angeloi held various high titles and military commands under Emperor Manuel I Komnenos. In 1185, following a revolt against Andronikos I Komnenos, Isaac II Angelos rose to the throne establishing the Angeloi as the new imperial family that ruled until 1204. The period was marked by the decline and fragmentation of the Byzantine Empire, culminating in its dissolution by the Fourth Crusade in 1204 under Alexios IV Angelos.
The Byzantine Empire was ruled by emperors of the Komnenos dynasty for a period of 104 years, from 1081 to about 1185. The Komnenian period comprises the reigns of five emperors, Alexios I, John II, Manuel I, Alexios II and Andronikos I. It was a period of sustained, though ultimately incomplete, restoration of the military, territorial, economic and political position of the Byzantine Empire.
The Byzantine Empire was ruled by emperors of the Angelos dynasty between 1185 and 1204 AD. The Angeloi rose to the throne following the deposition of Andronikos I Komnenos, the last male-line Komnenos to rise to the throne. The Angeloi were female-line descendants of the previous dynasty. While in power, the Angeloi were unable to stop the invasions of the Turks by the Sultanate of Rum, the uprising and resurrection of the Bulgarian Empire, and the loss of the Dalmatian coast and much of the Balkan areas won by Manuel I Komnenos to the Kingdom of Hungary.
Sebastokrator, was a senior court title in the late Byzantine Empire. It was also used by other rulers whose states bordered the Empire or were within its sphere of influence. The word is a compound of sebastós and krátōr. The wife of a Sebastokrator was named sebastokratorissa in Greek, sevastokratitsa (севастократица) in Bulgarian and sebastokratorica in Serbian.
The following outline is provided as an overview of and topical guide to the Byzantine Empire:
The Empire of Thessalonica is a historiographic term used by some modern scholars to refer to the short-lived Byzantine Greek state centred on the city of Thessalonica between 1224 and 1246 and ruled by the Komnenodoukas dynasty of Epirus. At the time of its establishment, the Empire of Thessalonica, under the capable Theodore Komnenos Doukas, rivaled the Empire of Nicaea and the Second Bulgarian Empire as the strongest state in the region, and aspired to capturing Constantinople, putting an end to the Latin Empire, and restoring the Byzantine Empire that had been extinguished in 1204.
The Byzantine Empire was ruled by emperors of the Doukas dynasty between 1059 and 1081. There are six emperors and co-emperors of this period: the dynasty's founder, Emperor Constantine X Doukas, his brother John Doukas, katepano and later Caesar, Romanos IV Diogenes, Constantine's son Michael VII Doukas, Michael's son and co-emperor Constantine Doukas, and finally Nikephoros III Botaneiates, who claimed descent from the Phokas family.
