The Taj-e Haydari, was a type of headdress introduced circa 1501–1502 during the early Safavid era in Iran, when the future Shah Ismail captured Tabriz. The headdress consisted in a cap with a tall red projection, often wrapped in a white turban around its base. The tall red projection has 12 sides, in memory of the twelve Shiite imams, and may be complemented by a red plume in the center.
