"Pax Cultura" ("Cultural Peace" or "Peace through Culture") is the motto of the cultural artifact protection movement founded by Nicholas Roerich, and is symbolized by a maroon on white emblem consisting of three solid circles in a surrounding circle. On April 15, 1935 the Roerich Pact was signed by the United States and Latin American nations, agreeing that "historic monuments, museums, scientific, artistic, educational and cultural institutions" should be protected both in times of peace and war, and identified by their flying a distinctive flag, the "Banner of Peace", bearing the Pax Cultura emblem.
