Chief secretary to Parthian monarch, Artabanus IV (died 224)
Dad-windad (also spelled Dad-bendad) was a Parthian grandee, who served as the chief secretary (dabirbad) of the last Arsacid monarch, Artabanus IV (r. 213–224). He took part in the climactic battle of Hormozdgan in 224 between the Arsacid and Sasanian forces, which resulted in the defeat and death of Artabanus IV, with Dad-windad meeting his end shortly afterwards.
