Tiraz (Arabic: طراز, romanized: ṭirāz; Persian: تراز, romanized: tarāz or terāz) The Persian word for a type of embroidery and clothing textiles, are medieval Islamic embroideries, usually in the form of armbands sewn onto robes of honour (khilat). They were bestowed upon high-ranking officials who showed loyalty to the Caliphate, and given as gifts to distinguished individuals. They were usually inscribed with the ruler's names, and were embroidered with threads of precious metal and decorated with complex patterns. Tiraz were a symbol of power; their production and export were strictly regulated, and were overseen by a government-appointed official.
They were likely influenced by the tablion, a decorated patch added to the body of the mantle as a badge of rank or position in late Roman and Byzantine dress.
