Jiajak Jaqeli
Jiajak Jaqeli was the Empress consort of Alexios II of Trebizond.
Adrianos Komnenos
Adrianos Komnenos was a Byzantine aristocrat and general, and a younger brother of the Byzantine emperor Alexios I Komnenos( r. 1081– 1118).
Constantine Euphorbenos Katakalon
Constantine Euphorbenos Katakalon was a Byzantine noble and one of the most prominent generals of the reign of Alexios I Komnenos.
A descendant of the noble Katakalon and Euphorbenos families, Constantine is first mentioned in the sources when he commanded the Chomatenoi corps and the Turkish contingent of Alexios Komnenos' army in the Battle of Kalavrye in 1078.
He appears again in the lists of the Synod of Blachernae in 1094, bearing the title of" protokouropalates", and ranking in the 20th place among those aristocrats and court officials attending.
In the next year, he took part in Alexios' campaign against the Cumans and the impostor pretender Constantine Diogenes.
Alexios sent him to attack the Cumans while they were crossing the Zygos pass, but the latter, guided by local Vlachs, managed to cross the pass sooner and seize the town of Goloe.
Katakalon nevertheless attacked the Cuman foraging parties and managed to capture about a hundred prisoners, for which he was promoted to" nobelissimos".
He was next dispatched to assist the city of Adrianople, which was being besieged by the Cumans.
He attempted to enter the city from the south, but was surprised by the Cumans on the march, and barely escaped with his life.
Shortly after, he assisted Alakaseus in capturing the pretender at Poutza near Adrianople.
In 1096, the emperor sent him to rescue the remnants of the People's Crusade, which had been defeated and almost destroyed by the Seljuks.
The Turks withdrew before his advance, and Katakalon managed to rescue the surviving crusaders.
In, he was named" doux"( military governor) of Cyprus, and held that post at least until 1102/04.
One of his surviving seals mentions him as both" doux" of Cyprus and" kouropalates", rather than" nobelissimos"; this may imply that Katakalon had already served in this post before, prior to his promotion.
In 1108, Katakalon was part of an embassy sent by Alexios to Bohemond, who was besieging the imperial fortress of Dyrrhachium.
The Byzantine delegation convinced the Norman prince to seek a settlement with the Empire, and accompanied him to the imperial camp at Deabolis, where the namesake treaty was signed.
Katakalon was one of Alexios' most trusted and esteemed officials.
In token of this, his son Nikephoros was given the hand of Maria Komnene, the emperor's second daughter, in marriage.
Together they had several children.
George II of Constantinople
George II Xiphilinos or Xiphilinus(? – 7 July 1198) was the Patriarch of Constantinople between 1191 and 1198 AD.
According to Balsamon, George, during the reign of Alexios I Komnenos, added one member to the" Exocatacoeli"( an office similar to the Catholic cardinal in the Greek Church of the time), making it six.
Alexios Komnenos (co-emperor)
Alexios Komnenos, latinised as Alexius Comnenus , was the eldest son of the Byzantine emperor John II Komnenos and his wife Eirene of Hungary.
He was born in February 1106 at Balabista (today "Sidirokastro") in Macedonia, was made co-emperor with his father at 16 or 17 years of age and died on 2 August 1142 at Attalia, Pamphylia.
He was an elder brother of the emperor Manuel I Komnenos, and had a twin sister, Maria Komnene (plus other siblings).
George Palaiologos
George (Georgios) Palaiologos or Palaeologus  was a Byzantine general, one of the most prominent military commanders and supporters of Emperor Alexios I Komnenos (r. 1081–1118).
He was the son of the first known member of the Palaiologos family, the "strategos" of Mesopotamia Nikephoros Palaiologos.
His wife Anna Doukaina was the sister of Irene Doukaina, the wife of Alexios I Komnenos, making him the emperor's brother-in-law.
As Alexios Komnenos’ leading general and close friend, he played an important role in his campaigns, especially the Battle of Dyrrhachium against the Normans or the Battle of Levounion against the Pechenegs.
He was the chief source used by Anna Komnene in her "Alexiad" on her father’s battles, and is very favourably portrayed by her in her book as both capable and loyal.
Nikephoros Katakalon
Nikephoros Euphorbenos Katakalon was a Byzantine aristocrat and son-in- law of Emperor Alexios I Komnenos.
He was the son of the distinguished general Constantine Euphorbenos Katakalon, one of Alexios' most trusted officials.
As a token of Alexios' appreciation for Constantine, Nikephoros was married to the" porphyrogennete" Maria, the emperor's second daughter, and raised to the rank of" panhypersebastos".
From the" Alexiad", he is known to have participated in combat against the Cumans in 1095, alongside his father, where he distinguished himself by his bravery.
It is unknown when he died, but he is recorded as being dead by 1130.
With Maria, he had numerous children, but only two sons, Alexios Komnenos and Andronikos, are known by name, having held senior positions later in the century.
Another son, John, is known only by his commemoration in the" typikon" of the Monastery of Christ Philanthropos.
The couple also had an unknown number of daughters( at least three according to Varzos), as their existence is mentioned in the" typikon" of the Kecharitomene Monastery.
Theodora Kantakouzene
Theodora Komnene Kantakouzene( c. 1340 – after 1390) was the Empress consort of Alexios III of Trebizond.
John II Komnenos
John II Komnenos or Comnenus ("Iōannēs II Komnēnos"; 13 September 1087 – 8 April 1143) was Byzantine emperor from 1118 to 1143.
Also known as "John the Beautiful" or "John the GoodKaloïōannēs"), he was the eldest son of Emperor Alexios
I Komnenos and Irene Doukaina and the second emperor to rule during the Komnenian restoration of the Byzantine Empire.
John was a pious and dedicated monarch who was determined to undo the damage his empire had suffered following the battle of Manzikert, half a century earlier.
John has been assessed as the greatest of the Komnenian emperors.
In the course of his twenty-five year reign, John made alliances with the Holy Roman Empire in the west, decisively defeated the Pechenegs, Hungarians and Serbs in the Balkans, and personally led numerous campaigns against the Turks in Asia Minor.
John's campaigns fundamentally changed the balance of power in the east, forcing the Turks onto the defensive and restoring to the Byzantines many towns, fortresses and cities right across the Anatolian peninsula.
In the southeast, John extended Byzantine control from the Maeander in the west all the way to Cilicia and Tarsus in the east.
In an effort to demonstrate the Byzantine ideal of the emperor's role as the leader of the Christian world, John marched into Muslim Syria at the head of the combined forces of Byzantium and the Crusader states; yet despite the great vigour with which he pressed the campaign, John's hopes were disappointed by the evasiveness of his Crusader allies and their reluctance to fight alongside his forces.
Under John, the empire's population recovered to about 10 million people.
The quarter-century of John II's reign is less well recorded by contemporary or near-contemporary writers than the reigns of either his father, Alexios I, or his son, Manuel I.
In particular little is known of the history of John's domestic rule or policies.
Nicholas Kallikles
Nicholas Kallikles was a prominent physician and a leading court poet active in the Byzantine court in Constantinople during the reigns of Alexios I Komnenos( r. 1081– 1118) and John II Komnenos( r. 1118–1143).
