"[1] Shapur IV was the son of Yazdegerd I and Shushandukht, and had two brothers named Bahram V and Narse.

During Shapur's reign in Armenia, he concentrated on reconciliation and established friendly relations with the nobles.

He made every effort to convert the Christian Armenians to Zoroastrianism, but was largely unsuccessful.

However, he only managed to reign during a short time, until he was murdered by the nobles and the clergy, who sought to expel all the sons of Yazdegerd I.

The image of the Sassanid emperor is usually included on the front of the coin, but on the reverse side of the coin, instead of the fire altar and its two attendantss, the image of Shapur IV with an unusual hat decorated with two ram's horns can be seen.
