Alexios III Angelos, Latinized as Alexius III Angelus, was Byzantine Emperor from March 1195 to 17/18 July 1203. He reigned under the name Alexios Komnenos associating himself with the Komnenos dynasty. A member of the extended imperial family, Alexios came to the throne after deposing, blinding and imprisoning his younger brother Isaac II Angelos. The most significant event of his reign was the attack of the Fourth Crusade on Constantinople in 1203, on behalf of Alexios IV Angelos. Alexios III took over the defence of the city, which he mismanaged, and then fled the city at night with one of his three daughters. From Adrianople, and then Mosynopolis, he attempted unsuccessfully to rally his supporters, only to end up a captive of Marquis Boniface of Montferrat. He was ransomed and sent to Asia Minor where he plotted against his son-in-law Theodore I Laskaris, but was eventually captured and spent his last days confined to the Monastery of Hyakinthos in Nicaea, where he died.
Andronikos I Komnenos, Latinized as Andronicus I Comnenus, was Byzantine emperor from 1183 to 1185. He was the son of Isaac Komnenos and the grandson of the emperor Alexios I. In later Byzantine historiography, Andronikos I became known under the epithet "Misophaes" in reference to the great number of enemies he had blinded.
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.
Theodore Branas or Vranas, sometimes called Theodore Komnenos Branas, was a general under the Byzantine Empire and afterwards under the Latin Empire of Constantinople. Under the Latin regime he was given the title Caesar and in 1206 he became governor and lord of Adrianople. He is called Livernas by western chroniclers of the Fourth Crusade, including Geoffroi de Villehardouin.
Ivan Asen I, also known as Asen I or John Asen I, was emperor or tsar of Bulgaria from 1187/1188 to 1196 as co-ruler with his elder brother, Peter II. Hailing from the Byzantine theme of Paristrion, his exact place and date of birth are unknown. Most contemporaneous chronicles describe Asen and his brothers, Theodor (Peter) and Kaloyan, as Vlachs but they were probably of mixed Bulgarian, Cuman and Vlach ancestry.
AlexiosBranas or Vranas was a Byzantine nobleman, attempted usurper, and the last Byzantine military leader of the 12th century to gain a notable success against a foreign enemy.
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.
Manuel Komnenos was the eldest son of Byzantine emperor Andronikos I Komnenos, and the progenitor of the Grand Komnenos dynasty of the Empire of Trebizond. He served his uncle, Manuel I Komnenos, as a diplomatic envoy to the Russian principalities and the Kingdom of Jerusalem, but also helped his father escape imprisonment in Constantinople. His opposition to the regency of Empress-dowager Maria of Antioch and the protosebastos Alexios Komnenos landed him in prison, but he was released in April 1182, when his father stood poised to take power in the Byzantine capital.
The Byzantine Empire experienced cycles of growth and decay over the course of nearly a thousand years, including major losses during the early Muslim conquests of the 7th century.
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.
Wars between the Normans and the Byzantine Empire were fought from c. 1040 until 1185, when the final Norman invasion of the Byzantine Empire was defeated.
The sack of Constantinople occurred in April 1204 and marked the culmination of the Fourth Crusade. Crusader armies captured, looted, and destroyed parts of Constantinople, then the capital of the Byzantine Empire. After the capture of the city, the Latin Empire was established and Baldwin of Flanders was crowned Emperor Baldwin I of Constantinople in the Hagia Sophia.
The Massacre of the Latins was a large-scale massacre of the Roman Catholic inhabitants of Constantinople, the capital of the Eastern Roman Empire, by the Eastern Orthodox population of the city in April 1182.
The Battle of Demetritzes in 1185 was fought between the Byzantine army and the Normans of the Kingdom of Sicily, who had recently sacked and captured the Byzantine Empire's second city, Thessalonica. It was a decisive Byzantine victory, which led to the immediate re-occupation of Thessalonica and ended the Norman threat to the Empire.
Constantine Angelos was a Byzantine aristocrat who married into the Komnenian dynasty and served as a military commander under Manuel I Komnenos, serving in the western and northern Balkans and as an admiral against the Normans. He was the founder of the Angelos dynasty, which went on to rule the Byzantine Empire in 1185–1204 and found and rule the Despotate of Epirus (1205–1318) and the Empire of Thessalonica (1224–1242/46).
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.
John Komnenos was the second son of the Byzantine aristocrat, and emperor in 1183–1185, Andronikos I Komnenos. His father appointed him co-emperor over his older brother Manuel, but when Andronikos was deposed on 12 September 1185, John was also seized and probably killed.
Euphrosyne Kastamonitissa was a Byzantine noblewoman of the Kastamonites family, a wife of Andronikos Doukas Angelos and mother of the two future Byzantine emperors from the Angelos family: Isaac II Angelos and Alexios III Angelos.
A Byzantine–Hungarian War was fought between Byzantine and Hungarian forces in the Balkans from 1180 to 1185. Taking advantage of the internal conflicts in the Byzantine Empire after Emperor Manuel's death, Béla III of Hungary reoccupied Croatia, Dalmatia and Syrmia, restoring Hungarian suzerainty over these territories after fourteen years.
