Flag of the Knights Hospitaller - Red Cross with Star and Crescent #177100 (License: Personal Use)

This flag represents the Order of the Knights Hospitaller during the Crusades, incorporating a red Latin cross (symbol of Christianity), a red star, and a red crescent (both associated with Islamic heraldry), signifying truce or alliance with Muslim powers. Historically used in treaties and banners during the 12th-13th centuries, it reflects rare interfaith cooperation in medieval warfare and governance. The design appears in chronicles like those of William of Tyre and in later heraldic reconstructions.

Used in historical articles, museum exhibits, educational content on the Crusades, and digital archives about medieval military orders; targets users researching religious symbolism, heraldry, or cross-cultural diplomacy in the Middle Ages.
