Arius
Exile, return, and death

The homoousian party's victory at Nicaea was short-lived, however. Despite Arius' exile and the alleged finality of the Council's decrees, the Arian controversy recommenced at once. When Bishop Alexander died in 327, Athanasius succeeded him, despite not meeting the age requirements for a hierarch. Still committed to pacifying the conflict between Arians and Trinitarians, Constantine gradually became more lenient toward those whom the Council of Nicaea had exiled. Though he never repudiated the council or its decrees, the emperor ultimately permitted Arius (who had taken refuge in Palestine) and many of his adherents to return to their homes, once Arius had reformulated his Christology to mute the ideas found most objectionable by his critics. Athanasius was exiled following his condemnation by the First Synod of Tyre in 335 (though he was later recalled), and the Synod of Jerusalem the following year restored Arius to communion. The emperor directed Alexander of Constantinople to receive Arius, despite the bishop's objections; Bishop Alexander responded by earnestly praying that Arius might perish before this could happen.

Modern scholars consider that the subsequent death of Arius may have been the result of poisoning by his opponents. In contrast, some contemporaries of Arius asserted that the circumstances of his death were a miraculous consequence of Arius's heretical views. The latter view was evident in the account of Arius's death by a bitter enemy, Socrates Scholasticus:

It was then Saturday, and Arius was expecting to assemble with the church on the day following: but divine retribution overtook his daring criminalities. For going out of the imperial palace, attended by a crowd of Eusebian partisans like guards, he paraded proudly through the midst of the city, attracting the notice of all the people. As he approached the place called Constantine's Forum, where the column of porphyry is erected, a terror arising from the remorse of conscience seized Arius, and with the terror a violent relaxation of the bowels: he therefore enquired whether there was a convenient place near, and being directed to the back of Constantine's Forum, he hastened thither. Soon after a faintness came over him, and together with the evacuations his bowels protruded, followed by a copious hemorrhage, and the descent of the smaller intestines: moreover portions of his spleen and liver were brought off in the effusion of blood, so that he almost immediately died. The scene of this catastrophe still is shown at Constantinople, as I have said, behind the shambles in the colonnade: and by persons going by pointing the finger at the place, there is a perpetual remembrance preserved of this extraordinary kind of death.

The death of Arius did not end the Arian controversy, which would not be settled for centuries in some parts of the Christian world.
