Bahram I in the context of "Kartir"

A radiant or radiate crown, also known as a solar crown, sun crown, Eastern crown, or tyrant's crown, is a crown, wreath, diadem, or other headgear symbolizing the Sun or more generally powers associated with the Sun. It comprises a number of narrowing bands going outwards from the wearer's head, to represent the rays of the Sun. These may be represented either as flat, on the same plane as the circlet of the crown, or rising at right angles to it.

Mani (/ˈmɑːni/; c. April AD 216 – 2 March AD 274 or 26 February AD 277) was an Iranian prophet and the founder of Manichaeism, a religion most prevalent in late antiquity.

Mani was born in or near Ctesiphon (south of modern Baghdad) in Mesopotamia, at the time part of the Parthian Empire. Seven of his major works were written in Syriac, and the eighth, dedicated to the Sasanian emperor Shapur I, was written in Middle Persian. He died shortly after being imprisoned by Bahram I in Gundeshapur.

Narseh (also spelled Narses or Narseus; Middle Persian: 𐭭𐭥𐭮𐭧𐭩) was the seventh King of Kings of Sasanian Iran from 293 to 303. The youngest son of Shapur I (r. 240–270), Narseh served as the governor of Sakastan, Hind and Turan under his father. Shapur I was eventually succeeded by his son Hormizd I (r. 270–271), who died after a reign of one year. Shapur I's eldest son Bahram I, who had never been considered as a candidate for succession to the throne by his father, ascended the throne with the aid of the powerful Zoroastrian priest Kartir. He then made a settlement with Narseh to give up his entitlement to the throne in return for the governorship of the important frontier province of Armenia, which was a persistent cause for war between the Roman and Sasanian Empires. Narseh held the title of Vazurg Šāh Arminān ("Great King of Armenia"), which was used by the heir to the throne in the early Sasanian times. Nevertheless, Narseh most likely still viewed Bahram I as a usurper.

The succession of Bahram I's son, Bahram II (r. 274–293) seemingly occurred without any issues. After Bahram II's death in 293, his son Bahram III was unwillingly crowned by a nobleman named Wahnam. The rest of the nobility did not support Bahram III's kingship, and asked Narseh to rule instead. Ultimately, Bahram III abdicated as shah, while Wahnam was executed. Narseh was the first Sasanian ruler to not ascend the throne as a crown prince. The circumstances of his rise to power are detailed in the Paikuli inscription, which he made as his own Res Gestae Divi Augusti and to legitimize his rule.

Hormizd-Ardashir, better known by his dynastic name of Hormizd I (also spelled Hormozd I or Ohrmazd I; Middle Persian: 𐭠𐭥𐭧𐭥𐭬𐭦𐭣), was the third Sasanian King of Kings (shahanshah) of Iran, who ruled from May 270 to June 271. He was the third-born son of Shapur I (r. 240–270), under whom he was governor-king of Armenia, and also took part in his father's wars against the Roman Empire. Hormizd I's brief time as ruler of Iran was largely uneventful. He built the city of Hormizd-Ardashir (present-day Ahvaz), which remains a major city today in Iran. He promoted the Zoroastrian priest Kartir to the rank of chief priest (mowbed) and gave the Manichaean prophet Mani permission to continue his preaching.

It was under Hormizd I that the title of "King of Kings of Iran and non-Iran" became regularized in Sasanian coinage; previously, the royal titulary had generally been "King of Kings of Iran". Hormizd I was succeeded by his eldest brother Bahram I.

Bahram II (also spelled Wahram II or Warahran II; Middle Persian: 𐭥𐭫𐭧𐭫𐭠𐭭) was the fifth Sasanian King of Kings (shahanshah) of Iran, from 274 to 293. He was the son and successor of Bahram I (r. 271–274). Bahram II, while still in his teens, ascended the throne with the aid of the powerful Zoroastrian priest Kartir, just like his father had done.

He was met with considerable challenges during his reign, facing a rebellion in the east led by his brother, the Kushano-Sasanian dynast Hormizd I Kushanshah, who also assumed the title of King of Kings and possibly laid claims to the Sasanian throne. Another rebellion, led by Bahram II's cousin Hormizd of Sakastan in Sakastan, also occurred around this period. In Khuzestan, a Zoroastrian factional revolt led by a high-priest (mowbed) occurred. The Roman emperor Carus exploited the turbulent situation of Iran by launching a campaign into its holdings in Mesopotamia in 283. Bahram II, who was in the east, was unable to mount an effective coordinated defense at the time, possibly losing his capital of Ctesiphon to the Roman emperor. However, Carus died soon afterwards, reportedly being struck by lightning. As a result, the Roman army withdrew, and Mesopotamia was reclaimed by the Sasanians. By the end of his reign, Bahram II had made peace with the Roman emperor Diocletian and put an end to the disturbances in Khuzestan and the east.
