The banner of peace is a symbol of the Roerich Pact.
This pact is the first international treaty dedicated to the protection of artistic and scientific institutions and historical monuments. It was signed on April 15, 1935. The banner of peace was proposed by Nicholas Roerich for an international pact for the protection of culture values.
Roerich described the sign thus:
“The proposed banner is the symbol of whole world, not a country, but the whole civilized world. The Banner proposed has on the white background three united amaranth spheres as a symbol of Eternity and Unity.”
