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.

Around the 7th century BC, the region of Persis in the southwestern portion of the Iranian plateau was settled by the Persians.
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.
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).
Cyrus the GreatCyrus II of Persia (600–530 BC; 𐎤𐎢𐎽𐎢𐏁 Kūruš), commonly known as Cyrus the Great, was the founder of the Achaemenid Empire, the First Persian Empire. Under his rule the empire embraced all of the previous civilized states of the ancient Near East, expanded vastly and eventually conquered most of Western Asia and much of Central Asia. Spanning from the Mediterranean Sea and Hellespont in the west to the Indus River in the east, the empire created by Cyrus was the largest the world had yet seen.
MedesThe Medes 'miːdz (Old Persian: Māda-; Akkadian: mat Mādāya, mat Mātāya; Ancient Greek: Mēdoi; Latin: ) were an ancient Iranian people who spoke the Median language and who inhabited an area known as Media between western and northern Iran. Around the 11th century BC, they occupied the mountainous region of northwestern Iran and the northeastern and eastern region of Mesopotamia in the vicinity of Ecbatana (present-day Hamadan). Their consolidation in Iran is believed to have occurred during the 8th century BC.
ZoroastrianismZoroastrianism is an Iranian religion and one of the world's oldest organized faiths, based on the teachings of the Iranian-speaking prophet Zoroaster. It has a dualistic cosmology of good and evil within the framework of a monotheistic ontology and an eschatology which predicts the ultimate conquest of evil by good.

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).
