Mithridates IV of Parthia

Mithridates IV (also spelled Mithradates IV; Parthian: 𐭌𐭄𐭓𐭃𐭕 Mihrdāt) was a Parthian king from to 57 to 54 BC. He was the son and successor of Phraates III (r. 69–57 BC). Mithridates IV's reign was marked by a dynastic struggle with his younger brother, Orodes II, who eventually emerged victorious and had Mithridates IV executed, thus succeeding him.
