Achaemenid EmpireThe Achaemenid Empire or Achaemenian Empire (əˈkiːmənᵻd; 𐎧𐏁𐏂, Xšāça, ) was the ancient Iranian empire founded by Cyrus the Great of the Achaemenid dynasty in 550 BC, also known as the First Persian Empire. Based in Western Asia, it was the largest empire the world had ever seen at its time, spanning a total of from the Balkans and Egypt in the west to Central Asia and the Indus Valley in the east. Around the 7th century BC, the region of Persis in the southwestern portion of the Iranian plateau was settled by the Persians.
Sasanian EmpireThe Sasanian Empire (səˈsɑːniən,_səˈseɪniən), officially known as Eranshahr ("Land/Empire of the Iranians"), was the last Iranian empire before the early Muslim conquests of the 7th–8th centuries AD. Named after the House of Sasan, it endured for over four centuries, from 224 to 651 AD, making it the longest-lived Persian imperial dynasty. The Sasanian Empire succeeded the Parthian Empire, and re-established the Persians as a major power in late antiquity alongside its neighbouring arch-rival, the Roman Empire (after 395 the Byzantine Empire).
Parthian EmpireThe Parthian Empire (ˈpɑrθiən), also known as the Arsacid Empire (ˈɑrsəsɪd), was a major Iranian political and cultural power in ancient Iran from 247 BC to 224 AD. Its latter name comes from its founder, Arsaces I, who led the Parni tribe in conquering the region of Parthia in Iran's northeast, then a satrapy (province) under Andragoras, who was rebelling against the Seleucid Empire. Mithridates I (171-132 BC) greatly expanded the empire by seizing Media and Mesopotamia from the Seleucids.
DeiocesDeioces (Δηιόκης), from the Old Iranian Dahyu-ka-, meaning "the lands" (above, on and beneath the earth), was the founder and the first shah as well as priest of the Medes. His name has been mentioned in different forms in various sources, including the Ancient Greek historian Herodotus, who has written his name as Δηιόκης (Dēiokēs). The exact date of the era of Deioces' rule is not clear and probably covered most of the first half of the seventh century BC. According to Herodotus, Deioces governed for 53 years.
AtropateneAtropatene (Ātṛpātakāna; Ἀτροπατηνή), also known as Media Atropatene, was an ancient Iranian kingdom established in 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").
Artabanus IV of ParthiaArtabanus 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 is the Latin form of the Greek Artábanos (Ἁρτάβανος), itself from the Old Persian *Arta-bānu ("the glory of Arta."). The Parthian and Middle Persian variant was Ardawān (𐭓𐭕𐭐𐭍). In 208, Vologases VI succeeded his father Vologases V as king of the Parthian Empire.

There is a fragmentary palimpsest dating to the fifth century. The earliest manuscripts of books 1–9 date to the tenth century, with a 13th-century manuscript containing the entire text.
Iranian peoplesThe Iranian peoples or Iranic peoples are a diverse grouping of Indo-European peoples who are identified by their usage of the Iranian languages and other cultural similarities. The Proto-Iranians are believed to have emerged as a separate branch of the Indo-Iranians in Central Asia around the mid-2nd millennium BC. At their peak of expansion in the mid-1st millennium BC, the territory of the Iranian peoples stretched across the entire Eurasian Steppe, from the Danubian plains in the west to the Ordos Plateau in the east and the Iranian Plateau in the south.
ParthiaParthia (𐎱𐎼𐎰𐎺 Parθava; 𐭐𐭓𐭕𐭅 Parθaw; 𐭯𐭫𐭮𐭥𐭡𐭥 Pahlaw) is a historical region located in northeastern Greater Iran. It was conquered and subjugated by the empire of the Medes during the 7th century BC, was incorporated into the subsequent Achaemenid Empire under Cyrus the Great in the 6th century BC, and formed part of the Hellenistic Seleucid Empire after the 4th-century BC conquests of Alexander the Great. The region later served as the political and cultural base of the Eastern Iranian Parni people and Arsacid dynasty, rulers of the Parthian Empire (247 BC – 224 AD).
