These conflicts thus brought about a renewal of naval activity, culminating in the Battle of the Hellespont in 324 between the forces of Constantine I under Caesar Crispus and the fleet of Licinius, which was the only major naval confrontation of the 4th century.

After his navy's defeat in the Battle of the Hellespont, Licinius withdrew his forces from the city of Byzantium across the Bosporus to Chalcedon in Bithynia.

Following the destruction of his naval forces Licinius evacuated his garrison from Byzantium which joined his main army in Chalcedon on the Asiatic shore of the Bosporus.

Constantine's army reached the environs of Chrysopolis before the forces of Licinius.

This Crassus is thought to be either the Publius Licinius Crassus ( consul 97 BC ) who was a governor in Hispania in the 90s, or his grandson by the same name, who in 57 – 56 BC commanded Julius Caesar's forces in Armorica ( Brittany ), which places him near the mouth of the Loire.

Nicomedia remained as the eastern ( and most senior ) capital of the Roman Empire until Licinius was defeated by Constantine the Great in 324.

The terms of this peace were posted by the victorious Licinius at Nicomedia on June 13, 313.

Before the decisive engagement, Licinius allegedly had a vision in which an angel recited him a generic prayer that could be adopted by all cults and which Licinius then repeated to his soldiers.

Also in 310, he lost Istria to Licinius, who could not continue the campaign, however, as Galerius fell mortally ill and died the next year.

Gaius fled the temple and tried to cross the Tiber on a wooden bridge while Pomponius and Licinius would stay back and cover his retreat, killing as many as they could until they were themselves felled.

The defeat of the superior fleet of Licinius in the Battle of the Hellespont by Crispus, Constantine ’ s eldest son and Caesar, compelled his withdrawal to Bithynia, where a last stand was made ; the Battle of Chrysopolis, near Chalcedon ( September 18 ), resulted in Licinius ' final submission.

Consequently, when Caesar nominated himself to stand for the consular elections of 59 BC, with the support of Gnaeus Pompeius Magnus and Marcus Licinius Crassus, Cato and the rest of the boni, fearing him to be a radical who would destroy the Mos maiorum, bribed heavily in order to ensure that Bibulus would be his consular colleague.

In 308, after the elevation of Licinius to Augustus, Maximinus and Constantine were declared filii Augustorum (" sons of the Augusti "), but Maximinus probably started styling himself after Augustus during a campaign against the Sassanids in 310.

On hearing the news, Maximinus mobilized against Licinius, and seized Asia Minor before meeting Licinius on the Bosphorus to arrange terms for peace.

In the summer of 311, Maxentius mobilized against Constantine while Licinius was occupied with affairs in the East.

Two alliances, Maximin and Maxentius, Constantine and Licinius, lined up against one another.
