Background and state of Pars
Fars Province, Pars (also known as Persis), a region in the southwestern Iranian plateau, was the homeland of a southwestern branch of the Iranian peoples, the Persians. It also was also the birthplace of the first Iranian Empire, the Achaemenid Empire, Achaemenids. The region served as the center of the empire until its conquest by the Macedonia (ancient kingdom), Macedonian king Alexander the Great (). Since the end of the 3rd or the beginning of the 2nd century BCE, Pars was ruled by local dynasts subject to the Hellenistic Seleucid Empire. These dynasts held the ancient Persian title of ''frataraka'' ("leader, governor, forerunner"), which is also attested in the Achaemenid-era. Later under the ''frataraka'' Wadfradad II (fl. 138 BC), Pars was made a vassal of the Iranian Parthian Empire, Parthian (Arsacid) Empire. The ''frataraka'' were shortly afterwards replaced by the Kings of Persis, most likely at the accession of the Arsacid monarch Phraates II (). Unlike the ''fratarakas'', the Kings of Persis used the title of shah ("king"), and laid foundations to a new dynasty, which may be labelled the Darayanids.Origins
New Persian and Arabic texts
There are various different sources regarding the relationship between Pabag, Sasan, and the first Sasanian Empire, Sasanian monarch Ardashir I (). According to the ''Shahnameh'' ("The Book of Kings") by the medieval Persian poet Ferdowsi (d. 1020), Sasan was a descendant of the mythological Kayanian rulers Dara II, Kay Darab, Dara I, Kay Bahman, Esfandiyar and Vishtaspa. The claim of Sasan belonging to the Kayanian family was designed in order to justify that Ardashir was descended from the ancient Kayanian kings, who reflected memories of the Achaemenids. Dara II, the last Kayanian king to rule before Alexander, is partly based on the last Achaemenid King of Kings, Darius III (), whose empire was indeed conquered by Alexander's forces. A son of Dara II named Sasan (called "the elder") fled to History of India, India and lived there in exile until his death. He was survived by a son who was likewise named Sasan (called "the younger"), "which continued in the family for four generations". A descendant of the family, likewise named Sasan, worked for Pabag, who was a local ruler in Pars. Pabag's daughter married Sasan and bore him a son named Ardashir. Following this, Sasan is no longer mentioned. The ''Shahnameh'' thus indicates that the ancestors of Sasan resided in India following Alexander's conquests. This report has been used by scholars to point out Sasan's Indo-Parthian connection. According to the medieval Iranian historian Al-Tabari (d. 923), Pabag was the son of Sasan and a princess named Rambihisht, who was from the Bazrangi, Bazrangid family, a dynasty of rulers in Pars. He presents Pabag as the father of Ardashir. Like Ferdowsi in his ''Shahnameh'', Al-Tabari also describes Sasan as a foreigner in Pars, however, unlike him, he does not mention Sasan's place of origins.Middle Persian texts
The Middle Persian text ''Kar-Namag i Ardashir i Pabagan'' ("Book of the Deeds of Ardashir, son of Pabag"), says the following regarding the ancestry of Ardashir: "Ardashir, the Kayanian, son of Pabag from the parentage of Sasan and from the lineage of King Dara". Another Middle Persian text, the ''Bundahishn'', however, gives the genealogy of Ardashir as following: "Ardashir son of Pabag whose mother (was) the daughter of Sasan son of Weh-afrid". This demonstrates the inconsistencies between Middle Persian texts regarding the origins of the Sasanian dynasty. Both sources regard Pabag as the father of Ardashir, whilst Sasan is presented as the latter's grandfather or ancestor.Roman and Armenian texts
In Roman Empire, Roman and Armenian sources, a different account appears. According to the Roman historians Agathias and George Syncellus, Sasan was the biological father of Ardashir, whilst Pabag was his stepfather. The Armenian writers Movses Khorenatsi and Agathangelos likewise call Sasan the father of Ardashir. However, they do not make any mention of Pabag. A Greek language, Greek variant of Agathangelos' work calls Ardashir "son of Sasanus, which is the origin of the Sasanian name of the Persian kings descended from him".Sasanian inscriptions and coinage
Ardashir, on his coin engravings and inscription on Naqsh-e Rostam, claims to be the son of "divine Pabag, the king". His son and successor, Shapur I (), on his inscriptions at Naqsh-e Rajab and Shapur I's inscription at the Ka'ba-ye Zartosht, Ka'ba-ye Zartosht, calls himself as a son of Ardashir I and grandson of Pabag. Although various figures named "Sasan" are mentioned in the inscription, none of them are associated with the House of Sasan. The Paikuli inscription of Shapur I's son Narseh (), however, makes direct references to the House of Sasan, such as the phrase "since the gods gave glory and rulership to the family of Sasan", which indicates that Narseh saw Sasan as his ancestor.Conclusions in modern scholarship
The modern historian Marek Jan Olbrycht suggests that Sasan was an Indo-Parthian prince who married a Persian princess and gave birth to Ardashir. In order to not be seen as a foreign dynasty, however, Ardashir and Shapur I minimized the role of Sasan. Pabag was seemingly the father-in-law and possibly adoptive father of Ardashir.Biography
Pabag ruled a small principality in the area of Banavan, Fars, Khir, south of the Bakhtegan Lake. He was a vassal of Gochihr, the Bazrangid king of the Persian capital of Istakhr, who was in turn a vassal of the Arsacid King of Kings. With the permission of Gochihr, Pabag sent Ardashir to the fortress of Darabgerd to serve under its commander, Tiri. Pabag reportedly served as a priest of the Anahid fire-temple, fire-temple of Anahita in Istakhr, which served as a rallying point of the local Persian soldiers, who worshipped the Iranian goddess. The Arsacid Empire, then ruled by Vologases V (), was at this time in decline, due to wars with the Romans, civil wars and regional revolts. The Roman emperor Septimius Severus () had invaded the Arsacid domains in 196, and two years later did the same, this time sacking the Arsacid capital of Ctesiphon. At the same time, revolts occurred in Media (region), Media and Pars. The Iranologist Touraj Daryaee argues that the reign of Vologases V was "the turning point in Arsacid history, in that the dynasty lost much of its prestige." The kings of Persis were now unable to depend on their weakened Arsacid overlords. Indeed, in 205 or 206, Pabag rebelled and overthrew Gochihr, taking Istakhr for himself. According to al-Tabari, it was at the urging of Ardashir that Pabag rebelled. However, Daryaee considers this statement unlikely, and states that it was in reality the eldest son Shapur (son of Pabag), Shapur that helped Pabag to capture Istakhr, as demonstrated by the latter's coinage which has portraits of both them. Pabag subsequently appointed Shapur as his heir. This was much to the dislike of Ardashir, who had become the commander of Darabgerd after the death of Tiri. In an act of defiance, Ardashir left for Firuzabad, Fars, Ardashir-Khwarrah, where he fortified himself, preparing to attack his brother Shapur after Pabag's death. Pabag died a natural death sometime between 207–210 and was succeeded by Shapur.; ; After his death, both Ardashir and Shapur started minted coins with the title of "king" and the portrait of Pabag. The observe of Shapur's coins had the inscription "(His) Majesty, King Shapur" and the reverse had "son of (His) Majesty, King Pabag". Shapur's reign, however, proved short; he died under obscure conditions in 211 or 212. Ardashir thus succeeded Shapur, and went on to conquer the rest of Iran, establishing the Sasanian Empire in 224. Pabag was also survived by a daughter named Denag (sister of Ardashir I), Denag, who married Ardashir.Notes
