October 28 - 312 - The Battle of the Milvian Bridge
The Battle of the Milvian Bridge is most well remembered for being the moment at which Constantine took on the Chi-Ro symbol after a portentous vision, then accepted Christianity after his victory. This fact is well reported by ancient chroniclers, especially Christians who lauded Constantine's rule as the beginning of a Christian age. Yet the Battle of the Milvian Bridge was also a massive political victory. Constantine defeated Maxentius when both men were Emperors. This odd situation would be resolved in Constantine's victory, which unified the Western Roman Empire under his rule. By 324, Constantine would also put the Eastern Roman Empire under his control, unifying the Empire and bringing about a new governmental form and religious approach in Europe.
