Siege
David Komnenos, the governor, had failed to prepare for the siege and banned defenders from disrupting Norman siege works, hindering the city's defense.The Byzantine relief armies failed to coordinate their efforts, and only two forces, under Theodore Choumnos and John Maurozomes, actually came to the city's aid. In the event, the Normans undermined the city's eastern wall, opening a breach through which they entered the city. They slaughtered the defenders and proceeded to sack the city. The conquest degenerated quickly into a full-scale massacre of the city's inhabitants, with estimates suggesting that around 7,000 to 8,000 corpses were found afterwards. The siege is extensively chronicled by the city's archbishop, Eustathius of Thessalonica, who was present in the city during and after the siege.
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.
Andronikos I Komnenos, Latinized as Andronicus I Comnenus, was Byzantine emperor from 1183 to 1185. A nephew of John II Komnenos, Andronikos rose to fame in the reign of his cousin Manuel I Komnenos, during which his life was marked by political failures, adventures, scandalous romances, and rivalry with the emperor.
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.
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 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–Norman wars were a series of military conflicts between the Normans and the Byzantine Empire fought from c. 1040 to 1186 involving the Norman-led Kingdom of Sicily in the west, and the Principality of Antioch in the Levant. The last of the Norman invasions, though having incurred disaster upon the Romans by sacking Thessalonica in 1185, was eventually driven out and vanquished by 1186.
The sack of Constantinople occurred in April 1204 and marked the culmination of the Fourth Crusade. Crusaders sacked and destroyed most of Constantinople, the capital of the Byzantine Empire. After the capture of the city, the Latin Empire was established and Baldwin of Flanders crowned as Emperor Baldwin I of Constantinople in Hagia Sophia.
The Massacre of the Latins was a large-scale massacre of the Roman Catholic inhabitants of Constantinople, the capital of the Byzantine 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 struggle for Constantinople was a complex series of conflicts following the dissolution of the Byzantine Empire by the Fourth Crusade in 1204, fought between the Latin Empire established by the Crusaders, various Byzantine successor states, and foreign powers such as the Second Bulgarian Empire and Sultanate of Rum, for control of Constantinople and supremacy in the former empire's territory.
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.
