* The rebel Ivanko is captured and executed by the Byzantine general Alexios Palaiologos

On 25 July 1261, Michael VIII's general Alexios Strategopoulos captured Constantinople from its last Latin Emperor, Baldwin II.

After Manzikert, the Byzantine government sent a new army to contain the Seljuk Turks under Isaac Komnenos, a brother of the future emperor Alexios I Komnenos, but this army was defeated and its commander captured in 1073.

A new army under Alexios Komnenos, reinforced by Seljuk troops sent by Malik Shah I, finally defeated the mercenaries and captured John Doukas in 1074.

In 1098, when Antioch had been captured after a long siege and the Crusaders were in turn themselves besieged in the city, Alexios marched out to meet them, but, hearing from Stephen of Blois that the situation was hopeless, he returned to Constantinople.

Much of Anatolia was recovered from the Seljuk Turks, who had captured it just prior to Alexios ' reign.

With the aid of the Crusaders, Alexios was able to regain the coasts of Western Anatolia and expand his influence eastwards: in 1104, a Byzantine squadron of 10 ships captured Laodicea and other coastal towns as far as Tripoli.

Despite initial successes and reinforcements under megas doux Alexios Komnenos Bryennios, the expedition was ultimately defeated in 1156, and 4 Byzantine ships were captured.

Euphrosyne and Alexios III fled across Greece to Thessalonica and Corinth, but were finally captured by Boniface of Montferrat and imprisoned.

* 1203 – Isaac II Angelos, restored Eastern Roman Emperor, declares his son Alexios IV Angelos co-emperor after pressure from the forces of the Fourth Crusade.

Alexios was the son of Ioannis Komnenos and Anna Dalassena, and the nephew of Isaac I Komnenos ( emperor 1057 – 1059 ).

Alexios ' father declined the throne on the abdication of Isaac, who was accordingly succeeded by four emperors of other families between 1059 and 1081.

Furthermore, to aid the conspiracy Maria had adopted Alexios as her son, though she was only five years older than he Maria was persuaded to do so on the advice of her own " Alans " and her eunuchs, who had been instigated to do his by Isaac Komnenos.

As a result, Alexios and Constantine, Maria's son, were now adoptive brothers and both Isaac and Alexios took an oath that they would safeguard his rights as emperor.

As stated in the Alexiad, Isaac and Alexios left Constantinople in mid-February 1081 to raise an army against Botaneiates.

From there she negotiated with the emperor for the safety of family members left in the capital, while protesting her sons ' innocence of hostile actions ; under the falsehood of making a vesperal visit to worship at the church, she deliberately excluded the grandson of Botaneiates and his loyal tutor, met with Alexios and Isaac and fled for the forum of Constantine.

Anna then protested that the family was in fear for their lives, her sons were loyal subjects ( Alexios and Isaac were discovered absent without leave ), and had learned of a plot by enemies of the Komnenoi to have them both blinded and had, therefore, fled the capital so they may continue to be of loyal service to the emperor.

After bribing the Western troops who had guarded the city, Isaac and Alexios Komnenos entered the capital victoriously on April 1, 1081.

By him she was the grandmother of Emperors Isaac II Angelos and Alexios III Angelos.

In 1195, while Isaac II was away hunting in Thrace, Alexios was acclaimed as emperor by the troops with the conniving of Alexios ' wife Euphrosyne Doukaina Kamatera.

Alexios IV Angelos, the son of the deposed Isaac II, had recently escaped from Constantinople and now appealed to the crusaders, promising to end the schism of East and West, to pay for their transport, and to provide military support to the crusaders if they helped him to depose his uncle and sit on his father's throne.

Isaac II, drawn from his prison and robed once more in the imperial purple, received his son, Alexios IV, in state.

His participation in the attempted usurpation of John Komnenos the Fat in 1200 had caused him to be imprisoned until the accession of Isaac II Angelos, who was restored to the throne after having been deposed and imprisoned by his brother Alexios III, and his son Alexios IV Angelos, who were placed on the throne by the intervention of the Fourth Crusade in July 1203.

By the beginning of 1204, Isaac II and Alexios IV had inspired little confidence among the people of Constantinople in their efforts to defend the city from the Latins and Venetians, who were restless and rioted when the money and aid promised by Alexios IV was not forthcoming.

The young Alexios IV was strangled in prison, while his father Isaac died shortly afterwards, his death variously attributed to fright, sorrow, or foul play.

He was the son of Isaac Komnenos and grandson of Emperor Alexios I Komnenos.

* 1093 – Isaac Komnenos, son of Byzantine Emperor Alexios I Komnenos

At the end of January, 1204, the influential court official Alexios Doukas Mourtzouphlos took advantage of riots in the capital to imprison Alexios IV and seize the throne as Emperor Alexios V. At this point Isaac II died, allegedly of shock, while Alexios IV was strangled on 28 or 29 January.

In this capacity, Alexios defeated the rebellions of Nikephoros Bryennios the Elder ( whose son or grandson later married Alexios ' daughter Anna ) and Nikephoros Basilakes, the first at the Battle of Kalavrye and the latter in a surprise night attack on his camp.

While the Byzantine troops were assembling for the expedition, Alexios was approached by the Doukas faction at court, who convinced him to join a conspiracy against Nikephoros III.

Alexios overcame this crisis by entering into an alliance with a horde of 40, 000 Cumans, with whose help he crushed the Pechenegs at Levounion in Thrace on 29 April 1091.

Dalassena was the effective administrator of the Empire during Alexios ' long absences in military campaigns: she was constantly at odds with her daughter-in-law and had assumed total responsibility for the upbringing and education of her granddaughter Anna Komnene.

The betrothal in 1180 of Alexios II to Agnes of France, daughter of Louis VII of France and his third wife Adèle of Champagne and at the time a child of nine, had not apparently been followed by their marriage.

Alexios gathered the money by plundering imperial tombs at the church of the Holy Apostles, though Henry's death in September 1197 meant the gold was never despatched.

* 1081 – Alexios I Komnenos is crowned Byzantine emperor at Constantinople, bringing the Komnenian dynasty to full power.

Urban II's movement took its first public shape at the Council of Piacenza, where, in March 1095, Urban II received an ambassador from the Byzantine Emperor Alexios I Komnenos asking for help against Muslim ( Seljuk ) Turks who had taken over most of formerly Byzantine Empire Anatolia.

Alexios and David, Tamar's relatives, were fugitive Byzantine princes raised at the Georgian court.

* November 7 – Byzantine general Alexios Branas decisively defeats the Normans at the Battle of Demetritzes, ending the Norman invasion of the Byzantine Empire.

The situation was complicated by the invasion of Sultan Kaykhusraw I of Rum at the instigation of the deposed Alexios III in 1211 ; however, the Nicaeans defeated the Seljuk army at the Battle of Antioch on the Meander where Theodore Laskaris killed the sultan in combat.

Coming to the throne at age nine, his reign began with immediate civil war between his designated regent, his father's friend John Kantakouzenos, and a self-proclaimed council of regency composed of his mother Anna, the patriarch John XIV Kalekas, and the megas doux Alexios Apokaukos.

Because at the time of the engagement Emperor Alexios I had no rightful male heirs to inherit the throne, young Constantine was proclaimed the co-emperor of the Byzantine Empire.

Bryennios successfully defended the walls of Constantinople against the attacks of Godfrey of Bouillon during the First Crusade ( 1097 ); conducted the peace negotiations between Alexios and Prince Bohemond I of Antioch ( the Treaty of Devol, 1108 ); and played an important part in the defeat of Melikshah, the Seljuq sultan of Rûm, at the Battle of Philomelion ( 1117 ).

Once at the pass Manuel decided to attack, despite the danger from further ambushes, and also despite the fact that he could have attempted to bring the Turks out of their positions to fight them on the nearby plain of Philomelion, the site of an earlier victory won by his grandfather Alexios.

In 1211, at Antioch on the Meander, Theodore defeated a major invasion by the Seljuks, who were backing a bid by Alexios III to return to power.

The close family relations and continued exchange between David and Uzun Hassan were betrayed to the Sultan by George Amiroutzes ( which involved an ambitious plan to send one of David's sons or Alexios to grow up at the court of Uzun Hassan in seeming opposition to Mehmed ), furnished an excuse to imprison David and his sons in March 1463.

By the time of the Emperor Alexios Komnenos in the late 11th century, the Byzantine Varangian Guard was largely recruited from Anglo-Saxons and " others who had suffered at the hands of the Vikings and their cousins the Normans ".
