Hormizd-Ardashir, better known by his dynastic name of Hormizd I, 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, 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, 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.
Hormizd II was king (shah) of the Sasanian Empire. He ruled for six years and five months, from 303 to 309. He was a son and successor of Narseh.
Shapur I was the second Sasanian King of Kings of Iran. The precise dating of his reign is disputed, but it is generally agreed that he ruled from 240 to 270, with his father Ardashir I as co-regent until the death of the latter in 242. During his co-regency, he helped his father with the conquest and destruction of the city of Hatra, whose fall was facilitated, according to Islamic tradition, by the actions of his future wife al-Nadirah. Shapur also consolidated and expanded the empire of Ardashir I, waged war against the Roman Empire, and seized its cities of Nisibis and Carrhae while he was advancing as far as Roman Syria. Although he was defeated at the Battle of Resaena in 243 by Roman emperor Gordian III, he was the following year able to win the Battle of Misiche and force the new Roman emperor Philip the Arab to sign a favorable peace treaty that was regarded by the Romans as "a most shameful treaty".
Ardashir II, was the Sasanian King of Kings of Iran from 379 to 383. He was the brother of his predecessor, Shapur II, under whom he had served as vassal king of Adiabene, where he fought alongside his brother against the Romans. Ardashir II was appointed as his brother's successor to rule interimly till the latter's son Shapur III reached adulthood. Ardashir II's short reign was largely uneventful, with the Sasanians unsuccessfully trying to maintain rule over Armenia.
Atropatene, also known as Media Atropatene, was an ancient Iranian kingdom established in c. 323 BC by the Persian satrap Atropates. The kingdom, centered in present-day northern Iran, was ruled by Atropates' descendants until the early 1st-century AD, when the Parthian Arsacid dynasty supplanted them. It was conquered by the Sasanians in 226, and turned into a province governed by a marzban ("margrave"). Atropatene was the only Iranian region to remain under Zoroastrian authority from the Achaemenids to the Arab conquest without interruption, aside from being briefly ruled by the Macedonian king Alexander the Great.
Ardashir I, also known as Ardashir the Unifier, was the founder of the Persian Sasanian Empire. He was also Ardashir V of the Kings of Persis, until he founded the new empire. After defeating the last Parthian shahanshah Artabanus IV on the Hormozdgan plain in 224, he overthrew the Arsacid dynasty and established the Sasanian dynasty. Afterwards, Ardashir called himself "shahanshah" and began conquering the land that he called Iran.
Artabanus I, incorrectly known in older scholarship as Artabanus II, was king of the Parthian Empire, ruling briefly from c. 127 to 124/3 BC. His short reign ended abruptly when he died during a battle against the Yuezhi in the east. He was succeeded by his son Mithridates II.
Artabanus IV, also known as Ardavan IV (Parthian:𐭓𐭕𐭐𐭍), incorrectly known in older scholarship as Artabanus V, was the last ruler of the Parthian Empire from c. 213 to 224. He was the younger son of Vologases V, who died in 208.
Artabanus II, incorrectly known in older scholarship as Artabanus III, was King of Kings of the Parthian Empire from 12 to 38/41 AD, with a one-year interruption. He was the nephew and successor of Vonones I. His father was a Dahae prince, whilst his mother was a daughter of the Parthian King of Kings Phraates IV

Pacorus II was the King of Kings of the Parthian Empire from 78 to 110. He was the son and successor of Vologases I.
Vologases V was King of Kings of the Parthian Empire from 191 to 208. As king of Armenia, he is known as Vologases II. Not much is known about his period of kingship of Armenia, except that he put his son Rev I on the Iberian throne in 189. Vologases succeeded his father Vologases IV as king of the Parthian Empire in 191; it is uncertain if the transition of power was peaceful or if Vologases took the throne in a civil war. When Vologases acceded the Parthian throne, he passed the Armenian throne to his son Khosrov I.
Vologases VI was the uncontested king of the Parthian Empire from 208 to 213, but afterwards fell into a dynastic struggle with his brother Artabanus IV, who by 216 was in control of most of the empire, even being acknowledged as the supreme ruler by the Roman Empire. Vologases VI continued to rule Seleucia until 221/2, and coin mints of him even appear in Mesopotamia until 228, when he was presumably defeated by the Sasanian Empire, who had previously defeated Artabanus IV and now succeeded the Parthians as the kings of Iran.
Pabag, was an Iranian prince who ruled Istakhr, the capital of Pars, from 205 or 206 until his death sometime between 207 and 210. He was the father, stepfather, grandfather, or father-in-law of Ardashir I, the founder of the Sasanian Empire. He was succeeded by his eldest son Shapur.

The Kings of Persis, also known as the Darayanids, were a series of Persian kings, who ruled the region of Persis in southwestern Iran, from the 2nd century BCE to 224 CE. They ruled as vassal kings of the Parthian Empire, until they toppled them and established the Sasanian Empire. They effectively formed some Persian dynastic continuity between the Achaemenid Empire and the Sasanian Empire.
Dad-windad was a Parthian grandee, who served as the chief secretary (dabirbad) of the last Arsacid monarch, Artabanus IV. 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.
