His three sons, Constantine II, Constantius II and Constans become emperors.

Julius Constantius was a paternal half-brother of the Roman Emperor Constantine I, which, in turn, meant Gallus was a half-first cousin of Constantine's sons, Constantine II, Constantius II and Constans.

Emperors Constans and Constantius, the two remaining sons of Constantine worked together at the urging of Pope Julius in response to this heresy that not only divided the church, but the state as well.

Constantius I " Chlorus " married twice ; his first wife St. Helena bore him a son, Constantine I whose second wife Fausta ( daughter of Maximian and Eutropia ; sister of Maxentius ; half-sister of Constantius I's second wife Theodora ) bore him three sons ( Constantine II, Constantius II, and Constans I ) and two daughters ( Constantia and Helena ); these children were nieces and nephews of Maxentius, half-nieces and half-nephews of Licinius ( who had married their father's half-sister ), and grandchildren of Maximian.

The second son of Constantine I and Fausta, he ascended to the throne with his brothers Constantine II and Constans upon their father's death.

Division of the Roman Empire among the Caesars appointed by Constantine I: from left to right, the territories of Constantine II ( emperor ) | Constantine II, Constans I, Dalmatius and Constantius II.

After the death of Constantine I ( May 337 ), this was the formal division of the Empire, until Dalmatius was killed and his territory divided between Constans and Constantius.

The massacre left Constantius, his older brother Constantine II, his younger brother Constans, and three cousins Gallus, Julian and Nepotianus as the only surviving male relatives of Constantine the Great.

Constantine received Britannia, Gaul, Hispania, and Mauretania, while Constans, though initially under the supervision of Constantine II, received Italy, Africa, Illyricum, Pannonia, Macedonia, and Achaea.

Meanwhile, his brother Constantine desired to retain control of Constans ' realm – leading Constantius ' two brothers into open conflict.

He defeated his brother Constantine II in 340, but anger in the army over his personal life and preference for his barbarian bodyguards saw the general Magnentius rebel, resulting in Constans ’ assassination in 350.

Constans was the third and youngest son of Constantine the Great and Fausta, his father's second wife.

On 25 December 333, Constantine I elevated Constans to the rank of Caesar at Constantinople.

Division of the Roman Empire among the Caesars appointed by Constantine I: from left to right, the territories of Constantine II ( emperor ) | Constantine II, Constans, Dalmatius and Constantius II.

After the death of Constantine I ( May 337 ), this was the formal division of the Empire, until Dalmatius was killed and his territory divided between Constans and Constantius.

At first, Constans was under the guardianship of Constantine II, and the original settlement saw Constans receiving the praetorian prefectures of Italy and Africa.

Constans managed to extract the prefecture of Illyricum and the diocese of Thrace, provinces that were originally part of what was meant to be ruled by his cousin Dalmatius as per Constantine I ’ s proposed division of the Empire after his death.

In this condemnation were included not only the Ecthesis ( the exposition of faith of the Patriarch Sergius for which the emperor Heraclius had stood sponsor ), but also the typus of Paul, the successor of Sergius, which had the support of the reigning Emperor ( Constans II ).

The Council settled a set of theological controversies that go back to the sixth century but had intensified under the Emperors Heraclius ( 610 – 641 ) and Constans II ( 641 – 668 ).

When Heraclius ' grandson Constans II took the throne, he saw the controversy as threatening the stability of the Empire and attempted to silence discussion, by outlawing speaking either in favour or against the doctrine.

The death of Heraclius in 641 had thrown the political situation in Constantinople into chaos, and his young grandson Constans II eventually succeeded him.

He pressed Emperor Constans II to withdraw the Ecthesis of Heraclius.

However, on the death of Emperor Heraclius and the ascension of Emperor Constans II, Pyrrhus returned to Constantinople and recanted of his acceptance of the Dyothelite (" two wills ") position.

Such Emperors as Basiliscus, Zeno, Justinian I, Heraclius, and Constans II published several strictly ecclesiastical edicts either on their own without the mediation of church councils, or they exercised their own political influence on the councils to issue the edicts.

Annoyed that Constans had received Thrace and Macedonia after the death of Dalmatius, Constantine demanded that Constans hand over the African provinces, which, in order to maintain a fragile peace, he agreed to do.

Additional complications also arose when Constans came of age, and Constantine, who had grown used to dominating his younger brother, would not relinquish the guardianship.

As a result of the dispute, the Byzantine Emperor Justinian II ordered Sergius I's abduction ( as his predecessor Constans II had done with Pope Martin I ), but with the assistance of the exarch of Ravenna, Sergius I was able to avoid trial in Constantinople.

After the followers of Eusebius of Nicomedia ( who was now the Patriarch of Constantinople ) had renewed their deposition of Athanasius at a synod held in Antioch in 341, they resolved to send delegates to Constans, Emperor of the West, and also to Julius, setting forth the grounds on which they had proceeded.

So furious were the Byzantine officials at this harsh rejection of the wishes of their emperor and patriarch that they threatened to roast Eugene, just as they had roasted Pope Martin I. Eugene was saved from the fate of his predecessor by the advance of the Muslims, who took Rhodes in 654 and defeated Constans himself in the naval battle of Phoenix ( 655 ).

After Constans ' son and successor, Constantine IV had overcome the Muslim siege of Constantinople in 678, he immediately set his sights on restoring communion with Rome: he wrote to Pope Donus suggesting a conference on the matter.

Pope Vitalian, who had hosted the visit of Constans II to Rome in 663, almost immediately declared himself in favor of the doctrine of the two wills of Christ.

They had apparently been used as the foundation of a portion of the city wall, reconstructed in 663 under the fear of an attack by the Byzantine emperor Constans II, the temple having been destroyed by order of the bishop, St Barbatus, to provide the necessary material ( A. Meomartini, 0.

But a suspicion that he and Martina had murdered Constantine led soon after to a revolt under the general Valentinus, who forced Heraklonas to accept his young nephew Constans II as co-ruler.

On his departure Constans removed a large number of bronze artworks, including the bronze tiles from the roof of the Pantheon, which had been dedicated to Christian worship.

Constans II supported Monothelitism, and had Maximus exiled for his refusal to agree to Monothelite teachings.

While Constantine prepared to send his son Constans back to deal with this crisis, word came that his general Gerontius had rebelled, raising his own man as co-emperor.

Constans is a diminutive nickname given to the Emperor, who had been baptized Herakleios and reigned officially as Constantine.

Pope Martin I had condemned both Monothelitism and Constans ' attempt to halt debates over it ( the Type of Constans ) in the Lateran Council of 649.
