Upon assuming imperial office, Constantine continued the purge instituted by Zoë and Theodora, removing the relatives of
Michael V from the court. He opened the treasury to Zoë and Theodora, made large gifts to potential supporters to secure their loyalty, and initiated a round of senatorial promotions. He retained his mistress from his years in exile — a relative of his second wife — named
Maria Skleraina. Eventually this arrangement was made official by means of a palace ceremony, and Sklerania was awarded the honorific
Sebastē.
Early conflicts By 1040 the situation in
Byzantine Italy had become precarious. The permanent settlement of
Normans in Southern Italy threatened Byzantine holdings, and a complicated series of diplomatic maneuvers to secure Byzantine control transpired between 1040 and 1042. These centered on
Argyros, a prominent Italian from
Bari, and culminated in the recall of the Byzantine general
George Maniakes from his command in
Italy. Fearing enemies at court, Maniakes had himself acclaimed emperor by his troops in September 1042. He transferred his troops into the
Balkans and won several battles against imperial armies as he marched towards Constantinople, but in late 1043 he was struck by a projectile and killed in battle. Immediately after the victory, Constantinople
was attacked by a fleet from the
Kievan Rus'. There is no direct evidence that the Rus' had colluded with Maniakes, but scholarly opinion remains divided. The Rus' raiders were defeated in a naval confrontation in the Bosporus by admiral
Basil Theodorokanos by means of
Greek fire. As part of the peace negotiations, Constantine married his daughter, Anastasia (by his second wife or Maria Skleraina), to the future Prince
Vsevolod I of Kiev, the son of his opponent
Yaroslav I the Wise. Constantine's family name
Monomachos ("one who fights alone") was inherited by Vsevolod and Anastasia's son,
Vladimir II Monomakh. surrenders to Emperor Constantine MonomachosConstantine's preferential treatment of Maria Skleraina in the early part of his reign led to rumors that she was planning to murder Zoë and Theodora. This led to a popular uprising by the citizens of Constantinople in 1044, which came dangerously close to harming Constantine as he participated in a religious
procession. The mob was only quieted by the appearance at a balcony of Zoë and Theodora, who reassured the people that they were not in any danger of
regicide. In 1045, Constantine annexed the
Armenian kingdom of
Ani, but this expansion merely removed a key border state between the empire and its enemies. Faced with the challenge of integrating a new people into the Byzantine polity, Constantine chose to persecute the
Armenian Church in an attempt to force it into union with the Orthodox Church. They
met in battle in Armenia in 1048 and settled a truce the following year. In 1046, Constantine concluded a treaty with the
Fatimid Caliph al-Mustansir Billah. The
Book of Gifts and Rarities records that on this occasion Constantine gave the caliph a gift of 500,000 gold coins, over two tons of gold.
The Pecheneg revolt and civil war chronicle. By the time of Constantine's reign the
Pecheneg people occupying the Bulgarian
steppe had served as a buffer between the Byzantines and the Rus' for decades. In the 1040s however, under external pressure from the
Oguz Turks, tens of thousands of Pechenegs migrated South of the Danube. After a period of war, crisis, raids, and Pecheneg civil war, these Southern Pechenegs were settled by the Byzantine administration in the North Balkans in 1046. This settlement proved controversial with the
Macedonians. That winter, Constantine was faced by the rebellion of his nephew
Leo Tornikios, an officer in
Adrianople. The reason for his rebellion is uncertain — possibly ultimately a family dispute — but the Macedonian
tagmata under his command had become disaffected following their demobilization after the conflict with the Pechenegs, and Tornikos was able to draw in anti-government elements from across the empire. He was proclaimed emperor by the army in the summer of 1047. Constantine assembled an army from the jails of Constantinople but this was quickly defeated and Tornikios put the city under siege. Tornikios was on the verge of taking the city but declined to press his advantage and Constantine was able to re-man the
walls. Eventually, Tornikios's army was won over by bribes and the rebellion was put down. Tornikios was blinded. The revolt had weakened Byzantine defenses in the
Balkans, and in 1048, the area was raided by those Pechenegs still North of the Danube. The same year, Constantine raised a force of 15,000 Pechenegs for his war against the Seljuks in the East, but they mutinied, raided across the
Bosporus, and by 1050 the Northern and Southern Pechenegs regrouped South of the Danube in open revolt. The Pechenegs plundered the Balkans until 1053, defeating three Byzantine armies, before the Byzantines exhausted them through counter-guerilla tactics. Historian
Anthony Kaldellis calls this "the worst string of Roman defeats in more than a century."

Maria Skleraina died around 1046, and Constantine took a new mistress with the title
sebaste: an "
Alan princess", identified by
Cyril Toumanoff as
Irene of Alania, the daughter of the Georgian prince
Demetrius and later wife of
sebastokrator Isaac Komnenos. Zoë also perished in 1050, and by that point Constantine's health had declined substantially as well: his arthritis was so severe as to render him incapable of walking unassisted. In 1050 or soon after, Constantine took the extraordinary step of substantially debasing the
nomisma, from 24 karats to 18. The reasons for this policy remain obscure; likely it was a way of reducing the pay of inactive
theme soldiers while compensating for a large budget deficit. Whatever motivated this action it was received without protest, unlike the much smaller debasement which took place under 100 years before under
Nikephoros II Phokas; though much smaller, Nikephoros's currency debasement led to riots and had to be repealed. It is in this later period of his reign that Constantine is also charged with demobilizing a large portion of the Eastern empire's standing army.
Scylitzes,
Kekaumenos, and
Attaleiates all accuse Constantine of dismantling the
Iberian theme, permanently relieving 50,000 standing troops in Armenia of their military duties at exactly the moment the empire had greatest need of them. Whether this was a mere fiscalization (i.e. an instance of the conversion of
strateia from a military obligation to a tax, an ongoing process in the 11th century) or a genuine disarmament is unclear, as are the motives for this change and its true scope. The contemporary sources are universal in ascribing this decision to Constantine's greed, but this is a historiographic convention applied whenever a new tax is imposed; it is likely the motive was financial. In later years many of Constantine's contemporaries looked back at this moment as the ultimate cause of the disaster at
Manzikert. In 1053, the Normans overcame the Byzantine forces led by
Argyrus in Southern Italy before the Byzantines could join with the forces of the Pope. Captured by the Normans,
Pope Leo IX sent delegates to Constantinople with intent of allying against the Normans, but instead of normalizing Papal-Byzantine relations, this embassy served to fracture them.
Great Schism , believed to be a gift to the Monastery of Saint George of Mangana (ca. 1047).In the year 1054 the tensions between the
Patriarch of Constantinople Michael Keroularios and
Pope Leo IX reached their boiling point, and personal
papal legates of Leo arrived in Constantinople. Constantine warmly received the legates, who before long were openly feuding with Keroularios and the monks of Constantinople. During this feud Leo died, but instead of returning to Rome, they remained in the City with Constantine's encouragement. Constantine urged Keroularios to restore communion between the churches but the patriarch refused. The conflict culminated in the legates issuing an
excommunication and placing the
bull on the altar of the
Hagia Sophia. Keroularios excommunicated the legates. The conflict persisted into late 1054 with more anathematizations following, and ultimately the hopes of Papal-Byzantine alliance in Southern Italy were dashed. Within a few years, the Pope would ally with the Normans instead. Constantine fell ill in late 1054 and died on 11 January of the following year. During his sickness he was persuaded by his councilors, chiefly the
logothetes tou dromou John, to ignore the rights of the elderly Theodora, daughter of Constantine VIII, and to pass the throne to the
doux of Bulgaria,
Nikephoros Proteuon. However, Theodora was recalled from her retirement and named empress. == Administration and legal reform ==
