Chi Rho is an early Christian symbol, which is still used by some branches of Christian religion, such as Catholicism. The symbol is created by Χ (chi) and Ρ (rho) is a composite symbol. This sign represents Jesus Christ. It is now known that the Roman Emperor Constantine first used the Kaile symbol to refer to Jesus. He claimed to get the revelation of Jesus from his dream, used the symbol and used it on his military flag, that is, the labran flag.
Because the two letters that make up the Chi Rho symbol Ρ And Χ It happens to be similar to the shape of the initial and final characters of the Latin peace "Pax", so sometimes this sign is also called Pax symbol or Pax cross. Therefore, although this symbol was first used in war, it also extended the idea of peace.
