On 26 October, 312 AD, the Roman Emperor Constantine the Great reportedly experienced a divine vision that would forever alter the course of Western history.
As legend recounts, he saw a blazing cross in the sky, accompanied by the words "In this sign, conquer."
This profound vision not only strengthened Constantine’s resolve but also led him to adopt the Christian faith as a personal and political compass, marking the beginning of Christianity’s rise within the Roman Empire.
At the Battle of the Milvian Bridge the following day, Constantine’s army, emboldened by this celestial sign, achieved a decisive victory.
Constantine’s embrace of Christianity post-victory would eventually transform it from a persecuted sect to the Empire’s dominant faith, a shift that laid the foundations for the Christian world of the medieval era and beyond.
