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.
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 Arab 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".
Mithridates I, also known as Mithridates I the Great, was king of the Parthian Empire from 165 BC to 132 BC. During his reign, Parthia was transformed from a small kingdom into a major political power in the Ancient East as a result of his conquests. He first conquered Aria, Margiana and western Bactria from the Greco-Bactrians sometime in 163–155 BC, and then waged war with the Seleucid Empire, conquering Media and Atropatene in 148/7 BC. In 141 BC, he conquered Babylonia and held an official investiture ceremony in Seleucia. The kingdoms of Elymais and Characene shortly afterwards became Parthian vassals. In c. 140 BC, while Mithridates was fighting the nomadic Saka in the east, the Seleucid king Demetrius II Nicator attempted to regain the lost territories; initially successful, he was defeated and captured in 138 BC, and shortly afterwards sent to one of Mithridates I's palaces in Hyrcania. Mithridates I then punished Elymais for aiding Demetrius, and made Persis a Parthian vassal.
Persis, also called Persia proper, is the Fars region, located to the southwest of modern-day Iran, now a province. The Persians are thought to have initially migrated either from Central Asia or, more probably, from the north through the Caucasus. They would then have migrated to the current region of Persis in the early 1st millennium BC. The country name Persia was derived directly from the Old Persian Parsa.
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.
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.
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 Battle of Hormozdgan was the climactic battle between the Arsacid and the Sasanian dynasties that took place on April 28, 224. The Sasanian victory broke the power of the Parthian dynasty, effectively ending almost five centuries of Parthian rule in Iran, and marking the official start of the Sasanian era.
Baydad, was a dynast (frataraka) of Persis from 164 to 146 BC.
The Sasanian dynasty was the house that founded the Sasanian Empire of Iran, ruling this empire from 224 to 651 AD. It began with Ardashir I, who named the dynasty in honour of his predecessor, Sasan.
Peroz I Kushanshah was Kushanshah of the Kushano-Sasanian Kingdom from 245 to 275. He was the successor of Ardashir I Kushanshah. He was an energetic ruler, who minted coins in Balkh, Herat, and Gandhara. Under him, the Kushano-Sasanians further expanded their domains into the west, pushing the weakened Kushan Empire to Mathura in North India.
Ardashir I Kushanshah was the first Kushanshah of the Kushano-Sasanian Kingdom from 233 to 245. He was succeeded by Peroz I Kushanshah.
Frataraka is an ancient Persian title, interpreted variously as “leader, governor, forerunner”. It is an epithet or title of a series of rulers in Persis from 3rd to mid 2nd century BC, or alternatively between 295 and 220 BC, at the time of the Seleucid Empire, prior to the Parthian conquest of West Asia and Iran. Studies of frataraka coins are important to historians of this period.
Shapur was an Iranian prince, who was the penultimate King of Persis from 207–210 to 211/2. He was succeeded by his younger brother Ardashir I, who founded the Sasanian Empire.
Wahbarz, known in Greek sources as Oborzos, was a dynast (frataraka) of Persis in the 1st half of the 2nd century BC, ruling from possibly c. 205 to 164 BC. His reign was marked by his efforts to establish Persis as a kingdom independent from Seleucid authority. He was able to reign independently for three decades, and even expanded to the west, seizing the Seleucid province of Characene. In 164 BC, the Seleucids repelled Wahbarz's forces from Characene, forcing him to re-submit as a Seleucid vassal. He was succeeded by Baydad.
Ardakhshir I was a dynast (frataraka) of Persis in the late 3rd-century BC, ruling sometime after 220 to c. 205 BC.
Wadfradad II was a dynast (frataraka) of Persis in the late 2nd-century BC, ruling sometime after 138 BC. He was appointed as frataraka by the Parthian king Mithridates I, who granted him more autonomy, most likely in an effort to maintain healthy relations with Persis as the Parthian Empire was under constant conflict with the Saka, Seleucids, and Characene. The coinage of Wadfradad II shows influence from the coins minted under Mithridates I. Wadfradad II was succeeded by Darayan I, the first of the Kings of Persis.
Darayan I was the first king of Persis, most likely invested with kingship of the region by his overlord, the Parthian monarch Phraates II sometime after 132 BC.
Pakor I was king of Persis in the first half of the 1st century CE, a vassal state of the Parthian Empire. He is known to have adopted on his coins the same hairstyle used on the coins of the Parthian king Phraates III.
