Alexios I Komnenos ( grc-gre, Ἀλέξιος Κομνηνός, 1057 – 15 August 1118;
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
The Komnenian restoration is the term used by historians to describe the military, financial, and territorial recovery of the Byzantine Empire under the Komnenian dynasty, from the accession of Alexios I Komnenos in 1081 to the death of Andron ...

First Crusade.
Biography
Alexios was the son of
John Komnenos and
Anna Dalassene,
[Kazhdan 1991, p. 63] and the nephew of
Isaac I Komnenos
Isaac I Komnenos or Comnenus ( grc-gre, Ἰσαάκιος Κομνηνός, ''Isaakios Komnēnos''; – 1 June 1060) was Byzantine emperor from 1057 to 1059, the first reigning member of the Komnenian dynasty.

Seljuk Turks.
[Norwich 1995, p. 4] Under
Michael VII Doukas ''Parapinakes'' (1071–1078) and
Nikephoros III Botaneiates (1078–1081), he was militarily employed, along with his elder brother
Isaac, against rebels in
Asia Minor,
Thrace, and in
Epirus.
[Bury 1911]
In 1074, western mercenaries led by
Roussel de Bailleul rebelled in Asia Minor,
[Norwich 1995, p. 2] but Alexios successfully subdued them by 1076.
["Alexiad", 1.1] In 1078, he was appointed commander of the field army in the West by Nikephoros III.
[Norwich 1995, p. 3] 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. Alexios was ordered to march against his brother-in-law
Nikephoros Melissenos in Asia Minor but refused to fight his kinsman. This did not, however, lead to a demotion, as Alexios was needed to counter the expected invasion of the
Normans of Southern Italy, led by

.
Conspiracy and revolt of the Komnenoi against Botaneiates
While Byzantine troops were assembling for the expedition, the Doukas faction at court approached Alexios and convinced him to join a
conspiracy against Nikephoros III. The mother of Alexios, Anna Dalassene, was to play a prominent role in this coup d'état of 1081, along with the current empress,
Maria of Alania.
[Garland 2007] First married to Michael VII Doukas and secondly to
Nikephoros III Botaneiates, she was preoccupied with the future of her son by Michael VII,
Constantine Doukas
Constantine X Doukas or Ducas ( el, Κωνσταντῖνος Δούκας, ''Kōnstantinos X Doukas'', 1006 – 23 May 1067), was Byzantine emperor from 1059 to 1067. He was the founder and first ruling member of the Doukid dynasty. Duri ...
. Nikephoros III intended to leave the throne to one of his close relatives,
[Finlay 1854, p. 59] and this resulted in Maria's ambivalence and alliance with the Komnenoi, though the real driving force behind this political alliance was Anna Dalassene.
The empress was already closely connected to the Komnenoi through Maria's cousin Irene's marriage to Isaac Komnenos,
so the Komnenoi brothers were able to see her under the pretense of a friendly family visit. Furthermore, to aid the conspiracy Maria had adopted Alexios as her son, though she was only five years older than he.
[Norwich 1995, p. 5] Maria was persuaded to do so on the advice of her own "Alans" and her eunuchs, who had been instigated by Isaac Komnenos. Given Anna's tight hold on her family, Alexios must have been adopted with her implicit approval.
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. By secretly giving inside information to the Komnenoi, Maria was an invaluable ally.

As stated in the Alexiad, Isaac and Alexios left Constantinople in mid-February 1081 to raise an army against Botaneiates. However, when the time came, Anna quickly and surreptitiously mobilized the remainder of the family and took refuge in the
Hagia Sophia. 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.
The tutor discovered they were missing and eventually found them on the palace grounds, but Anna was able to convince him that they would return to the palace shortly. Then to gain entrance to both the outer and inner sanctuary of the church, the women pretended to the gatekeepers that they were pilgrims from
Cappadocia who had spent all their funds and wanted to worship before starting their return trip. However, before they were to gain entry into the sanctuary, Straboromanos and royal guards caught up with them to summon them back to the palace.
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. She refused to go with them and demanded that they allow her to pray to the
Mother of God for protection. This request was granted and Anna then manifested her true theatrical and manipulative capabilities:

Nikephoros III Botaneiates was forced into a public vow that he would grant protection to the family.
Straboromanos tried to give Anna his cross, but for her it was not large enough for all bystanders to witness the oath. She also demanded that the cross be personally sent by Botaneiates as a vow of his good faith. He obliged, sending a complete assurance for the family with his own cross. At the emperor's further insistence, and for their own protection, they took refuge at the convent of Petrion, where they were eventually joined by
Maria of Bulgaria, mother of Irene Doukaina.
Botaneiates allowed them to be treated as refugees rather than as guests. They were allowed to have family members bring in their own food and were on good terms with the guards from whom they learned the latest news. Anna was highly successful in three important aspects of the revolt: she bought time for her sons to steal imperial horses from the stables and escape the city; she distracted the emperor, giving her sons time to gather and arm their troops; and she gave a false sense of security to Botaneiates that there was no real treasonous plot against him.
After bribing the Western troops guarding the city, Isaac and Alexios Komnenos entered the capital victoriously on 1 April 1081.
During this time, Alexios was rumored to be the lover of Empress
Maria, the daughter of King
Bagrat IV of Georgia, who had been successively married to
Michael VII Doukas and his successor Nikephoros III Botaneiates, and who was renowned for her beauty. Alexios arranged for Maria to stay on the palace grounds, and it was thought that he was considering marrying her. However, his mother consolidated the Doukas family connection by arranging the Emperor's marriage to
Irene Doukaina, granddaughter of the
Caesar John Doukas, the uncle of Michael VII, who would not have supported Alexios otherwise. As a measure intended to keep the support of the Doukai, Alexios restored

, the young son of Michael VII and Maria, as co-emperor and a little later betrothed him to his own first-born daughter
Anna, who moved into the Mangana Palace with her fiancé and his mother.
This situation changed drastically, however, when Alexios' first son
John II Komnenos was born in 1087:
[Kazhdan 1991, p. 658] Anna's engagement to Constantine was dissolved, and she was moved to the main Palace to live with her mother and grandmother. Alexios became estranged from Maria, who was stripped of her imperial title and retired to a monastery, and Constantine Doukas was deprived of his status as co-emperor.
Nevertheless, he remained on good terms with the imperial family and succumbed to his weak constitution soon afterwards.
Wars against the Normans, Pechenegs, and Tzachas
The thirty-seven year reign of Alexios was full of struggle. At the outset he faced the formidable attack of the Normans, led by

in
Thessaly (see
Battle of Dyrrhachium). Alexios suffered several defeats before he was able to strike back with success. He enhanced his resistance by bribing the German king
Henry IV with 360,000 gold pieces to attack the Normans in Italy, which forced the Normans to concentrate on their defenses at home in 1083–84. He also secured the alliance of
Henry, Count of Monte Sant'Angelo, who controlled the
Gargano Peninsula and dated his charters by Alexios' reign. Henry's allegiance would be the last example of Byzantine political control on peninsular Italy. The Norman danger subsided with the death of Guiscard in 1085, and the Byzantines recovered most of their losses.
Alexios next had to deal with disturbances in
Thrace, where the heretical sects of the
Bogomils and the
Paulicians revolted and made common cause with the
Pechenegs from beyond the
Danube. Paulician soldiers in imperial service likewise deserted during Alexios' battles with the Normans. As soon as the Norman threat had passed, Alexios set out to punish the rebels and deserters, confiscating their lands. This led to a further revolt near
Philippopolis, and the commander of the field army in the west, Gregory Pakourianos, was defeated and killed in the ensuing battle. In 1087 the Pechenegs raided into Thrace, and Alexios crossed into

). During his retreat, the emperor was surrounded and worn down by the Pechenegs, who forced him to sign a truce and to pay protection money. In 1090 the Pechenegs invaded Thrace again, while
Tzachas, the brother-in-law of the Sultan of
Rum, launched a fleet and attempted to arrange a joint siege of Constantinople with the Pechenegs. 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.
This put an end to the Pecheneg threat, but in 1094 the Cumans began to raid the imperial territories in the Balkans. Led by a pretender claiming to be

Asia Minor, which had been almost completely overrun by the
Seljuq Turks.
Byzantine–Seljuq Wars and the First Crusade

By the time Alexios ascended the throne, the Seljuqs had taken most of Asia Minor. Alexios was able to secure much of the coastal regions by sending peasant soldiers to raid the Seljuq camps, but these victories were unable to stop the Turks altogether. As early as 1090, Alexios had taken reconciliatory measures towards the

First Crusade at the
Council of Clermont later that same year. This was the
People's Crusade: a mob of mostly unarmed pilgrims led by the preacher
Peter the Hermit. Not quite ready to supply this number of people as they traversed his territories, the emperor saw his Balkan possessions subjected to further pillage at the hands of his own allies. Eventually Alexios dealt with the People's Crusade by hustling them on to Asia Minor. There, they were massacred by the Turks of
Kilij Arslan I at the
Battle of Civetot
The Battle of Civetot in 1096 brought an end to the People's Crusade, which was a poorly-armed movement of lower-class pilgrims of the First Crusade distinct from the subsequent and much more well-known Princes' Crusade.

The "Prince's Crusade", the second and much more formidable host of crusaders, gradually made its way to
Constantinople, led in sections by
Godfrey of Bouillon,
Bohemond of Taranto,
Raymond IV of Toulouse, and other important members of the western nobility. Alexios used the opportunity to meet the crusader leaders separately as they arrived, extracting from them oaths of homage and the promise to turn over conquered lands to the
Byzantine Empire. Transferring each contingent into Asia, Alexios promised to supply them with provisions in return for their oaths of homage. The crusade was a notable success for Byzantium, as Alexios recovered a number of important cities and islands. The
siege of Nicaea by the crusaders forced the city to surrender to the emperor in 1097, and the subsequent crusader victory at
Dorylaion allowed the Byzantine forces to recover much of western Asia Minor.

, the Seljuq Sultan of Iconium. In 1117 he moved onto the offensive and pushed his army deep into the Turkish-dominated Anatolian Plateau, where he defeated the Seljuq sultan at the
Battle of Philomelion.
Personal life

During the last twenty years of his life Alexios lost much of his popularity. The years were marked by persecution of the followers of the
Paulician
Paulicianism ( Classical Armenian: Պաւղիկեաններ, ; grc, Παυλικιανοί, "The followers of Paul"; Arab sources: ''Baylakānī'', ''al Bayāliqa'' )Nersessian, Vrej (1998). The Tondrakian Movement: Religious Movements in the ...
and
Bogomil heresies—one of his last acts was to publicly burn at the stake
Basil, a Bogomil leader, with whom he had engaged in a theological dispute.
In spite of the success of the First Crusade, Alexios also had to repel numerous attempts on his territory by the Seljuqs in 1110–1117.
Alexios was for many years under the strong influence of an ''eminence grise'', his mother
Anna Dalassene, a wise and immensely able politician whom, in a uniquely irregular fashion, he had crowned as ''
Augusta'' instead of the rightful claimant to the title, his wife Irene Doukaina. Alexios was never happier than when taking part in military exercises and he assumed personal command of his troops whenever possible. As such, Dalassene 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.
Succession
Alexios' last years were also troubled by anxieties over the succession. Although he had crowned his son
John II Komnenos co-emperor at the age of five in 1092, his wife Irene Doukaina wished to alter the succession in favor of their daughter Anna and Anna's husband,
Nikephoros Bryennios the Younger.
[Norwich 1995, p. 61] Bryennios had been made ''
kaisar'' (Caesar) and received the newly created title of ''
panhypersebastos'' ("honoured above all"), and remained loyal to both Alexios and John.
Pretenders and rebels
Apart from all of his external enemies, a host of rebels also sought to overthrow Alexios from the imperial throne, thereby posing another major threat to his reign.
Due to the troubled times the empire was enduring, he had by far the greatest number of rebellions against him of all the Byzantine emperors.

A search for the author of the publications uncovered the whole plot, yet Aron was only banished due to his connection to the royal line of Bulgaria, whose blood also flowed in the veins of the empress Irene.
Reform of the monetary system

Under Alexios the debased ''
solidus'' (''
tetarteron'' and ''
histamenon'') was discontinued and a gold coinage of higher fineness (generally .900–.950) was established in 1092, commonly called the ''
hyperpyron'' at 4.45 grs. The ''hyperpyron'' was slightly smaller than the ''solidus''.
It was introduced along with the
electrum ''
aspron trachy
The ''aspron'' ( el, ἄσπρον), from Latin ''asper'', was a late Byzantine name for silver or silver-alloy coins.

Legacy

Alexios I had overcome a dangerous crisis and stabilized the Byzantine Empire, inaugurating a century of imperial prosperity and success.
He had also profoundly altered the nature of the Byzantine government.
[Finlay 1854, p. 69] By seeking close alliances with powerful noble families, Alexios put an end to the tradition of imperial exclusivity and co-opted most of the nobility into his extended family and, through it, his government. Those who did not become part of this extended family were deprived of power and prestige.
This measure, which was intended to diminish opposition, was paralleled by the introduction of new courtly dignities, like that of ''
panhypersebastos'' given to Nikephoros Bryennios, or that of ''
sebastokrator'' given to the emperor's brother Isaac Komnenos.
Although this policy met with initial success, it gradually undermined the relative effectiveness of imperial bureaucracy by placing family connections over merit. Alexios' policy of integration of the nobility bore the fruit of continuity: every Byzantine emperor who reigned after Alexios I Komnenos was related to him by either descent or marriage.

Irene Doukaina, Alexios I had the following children:
