The Labarum

The Labarum is a Christian standard or banner that features the Chi-Rho symbol, which combines the first two letters of "Christ" in Greek (Χ and Ρ). It was used by the Roman Emperor Constantine the Great during the early 4th century, especially before the Battle of the Milvian Bridge, symbolizing his conversion to Christianity. The Labarum represents the triumph of Christianity over paganism and became a significant emblem in Christian tradition, often associated with divine protection and the moral authority of the Christian faith.
