It takes its name from the Milvian Bridge, an important route over the Tiber . Constantine won the battle and started on the path that led him to end the Tetrarchy and become the sole ruler of the Roman Empire . Maxentius drowned in the Tiber during the battle and his body was later taken from the river and decapitated . </P> <P> According to chroniclers such as Eusebius of Caesarea and Lactantius, the battle marked the beginning of Constantine's conversion to Christianity . Eusebius of Caesarea recounts that Constantine and his soldiers had a vision sent by the Christian God . This was interpreted as a promise of victory if the sign of the Chi - Rho, the first two letters of Christ's name in Greek, was painted on the soldiers' shields . The Arch of Constantine, erected in celebration of the victory, certainly attributes Constantine's success to divine intervention; however, the monument does not display any overtly Christian symbolism . </P> <P> The underlying causes of the battle were the rivalries inherent in Diocletian's Tetrarchy . After Diocletian stepped down on 1 May 305, his successors began to struggle for control of the Roman Empire almost immediately . Although Constantine was the son of the Western Emperor Constantius, the Tetrarchic ideology did not necessarily provide for hereditary succession . When Constantius died on 25 July 306, his father's troops proclaimed Constantine as Augustus in Eboracum (York). In Rome, the favorite was Maxentius, the son of Constantius' imperial colleague Maximian, who seized the title of emperor on 28 October 306 . But whereas Constantine's claim was recognized by Galerius, ruler of the Eastern provinces and the senior emperor in the Empire, Maxentius was treated as a usurper . Galerius, however, recognized Constantine as holding only the lesser imperial rank of Caesar . Galerius ordered his co-Augustus, Severus, to put Maxentius down in early 307 . Once Severus arrived in Italy, however, his army defected to Maxentius . Severus was captured, imprisoned, and executed . Galerius himself marched on Rome in the autumn, but failed to take the city . Constantine avoided conflict with both Maxentius and the Eastern emperors for most of this period . </P>
