The Arch of Constantine is a triumphal arch in Rome dedicated to the emperor Constantine the Great. The arch was commissioned by the Roman Senate to commemorate Constantine’s victory over Maxentius at the Battle of Milvian Bridge in AD 312.
The arch, which was constructed between 312 and 315, was dedicated by the Senate to commemorate ten years of Constantine’s reign (306–337) and his victory over the then reigning emperor Maxentius (306–312) at the Battle of Milvian Bridge on 28 October 312, as described on its attic inscription, and officially opened on 25 July 315. Not only did the Roman senate give the arch for Constantine’s victory, they also were celebrating decennia, a series of games that happens every decade for the Romans. On this occasion they also said many prayers. However, Constantine had actually entered Rome on 29 October 312, amidst great rejoicing, and the Senate then commissioned the monument. Constantine then left Rome within two months and did not return until 326.
