Media (region) in the context of "Adiabene"

The Iranian plateau or Persian plateau is a geological feature spanning parts of the Caucasus, Central Asia, South Asia, and West Asia. It makes up part of the Eurasian plate, and is wedged between the Arabian plate and the Indian plate. The plateau is situated between the Zagros Mountains to the west, the Caspian Sea and the Köpet Dag to the north, the Armenian Highlands and the Caucasus Mountains to the northwest, the Strait of Hormuz and the Persian Gulf to the south, and the Indian subcontinent to the southeast.

As a historical region, it includes Parthia, Media, Persis, and some of the previous territories of Greater Iran. The Zagros form the plateau's western boundary, and its eastern slopes may also be included in the term. The Encyclopædia Britannica excludes "lowland Khuzestan" explicitly and characterizes Elam as spanning "the region from the Mesopotamian plain to the Iranian Plateau".

The Medes were an Iron Age 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. In the 7th century BC, all of western Iran and some other territories were under Median rule, but their precise geographic extent remains unknown.

Although widely recognized as playing an important role in the history of the ancient Near East, the Medes left no written records to reconstruct their history. Knowledge of the Medes comes only from foreign sources such as the Assyrians, Babylonians, Armenians and Greeks, as well as a few Iranian archaeological sites, which are believed to have been occupied by Medes. The accounts related to the Medes reported by Herodotus convey the image of a powerful people, who would have formed an empire at the beginning of the 7th century BC that lasted until the 550s BC, played a pivotal role in the fall of the Assyrian Empire, and competed with the powerful kingdoms of Lydia and Babylonia.

The Parthian Empire (/ˈpɑːrθiən/), also known as the Arsacid Empire (/ˈɑːrsəsɪd/), was a major Iranian political and cultural power centered 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 (r. c. 171 – 132 BC) greatly expanded the empire by seizing Media and Mesopotamia from the Seleucids. At its height, the Parthian Empire stretched from the northern reaches of the Euphrates, in what is now central-eastern Turkey, to present-day Afghanistan and western Pakistan. The empire, located on the Silk Road trade route between the Roman Empire in the Mediterranean Basin and the Han dynasty of China, became a center of trade and commerce.

The Parthians largely adopted the art, architecture, religious beliefs, and regalia of their culturally heterogeneous empire, which encompassed Persian, Hellenistic, and regional cultures. For about the first half of its existence, the Arsacid court adopted elements of Greek culture, though it eventually saw a gradual revival of Iranian traditions. The Arsacid rulers were titled "King of Kings", claiming inheritance of the Achaemenid Empire; indeed, they accepted many local kings as vassals, although the Achaemenids would have had centrally appointed, albeit largely autonomous, satraps. The court did appoint a small number of satraps, largely outside Iran, but these satrapies were smaller and less powerful than the Achaemenid potentates. With the expansion of Arsacid power, the seat of central government shifted from Nisa to Ctesiphon along the Tigris (south of Baghdad), although several other sites also served as capitals.

Seleucus I Nicator (/sɪˈluːkəs/; Greek: Σέλευκος Νικάτωρ, Séleukos Nikátōr, "Seleucus the Victorious"; c. 358 BC – 281 BC) was a Macedonian Greek general, officer and successor of Alexander the Great who went on to found the eponymous Seleucid Empire, led by the Seleucid dynasty. Initially a secondary player in the power struggles following Alexander's death, Seleucus rose to become the total ruler of Asia Minor, Syria, Mesopotamia, and the Iranian plateau, assuming the title of basileus (king). The Seleucid Empire was one of the major powers of the Hellenistic world, until it was overcome by the Roman Republic and Parthian Empire in the late second and early first centuries BC.

While serving under Alexander, Seleucus was commander of the Hypaspistai, an elite Macedonian infantry unit. After the death of Alexander in June 323 BC, Seleucus initially supported Perdiccas, the regent of Alexander's empire, and was appointed Commander of the Companions and chiliarch at the Partition of Babylon in 323 BC. However, after the outbreak of the Wars of the Diadochi in 322, Perdiccas' military failures against Ptolemy in Egypt led to the mutiny of his troops in Pelusium. Perdiccas was betrayed and assassinated in a conspiracy by Seleucus, Peithon and Antigenes in Pelusium sometime in either 321 or 320 BC. At the Partition of Triparadisus in 321 BC, Seleucus was appointed Satrap of Babylon under the new regent Antipater. But almost immediately, the wars between the Diadochi resumed and one of the most powerful of the Diadochi, Antigonus, forced Seleucus to flee Babylon. Seleucus was only able to return to Babylon in 312 BC with the support of Ptolemy. From 312 BC, Seleucus ruthlessly expanded his dominions and eventually conquered the Persian and Median lands. Seleucus ruled not only Babylonia, but the entire eastern part of Alexander's empire.

Ancient Iranian religions were a set of ancient beliefs and practices of the Iranian peoples before the rise of Zoroastrianism. The religion closest to it was the historical Vedic religion that was practiced during the Vedic period. The major deities worshipped were Ahura Mazda and Mithra from Iran to Rome, but Atar was also worshipped, as names of kings and common public showing devotion to these three exist in most cases. But some sects, the precursors of the Magi, also worshipped Ahura Mazda, the chief of the Ahuras. With the rise of Zoroaster and his new, reformatory religion, Ahura Mazda became the principal deity, while the Daevas were relegated to the background. Many of the attributes and commandments of Varuna, called Fahrana in Median times, were later attributed to Ahura Mazda by Zoroaster.

The Iranian peoples emerged as a separate branch of the Indo-Iranians in the 2nd millennium BC, during which they came to dominate the Eurasian Steppe and the Persian Plateau. Their religion is derived from Iranian religions, and therefore shares many similarities with the Vedic religion of India. Although the Persian peoples left little written or material evidence of their religious practices, their religion is possible to reconstruct from scant Iranian, Babylonian and Greek accounts, similarities with Vedic and other Indo-European religions, and material evidence.

Datis or Datus (Greek: Δάτης, Old Iranian: *Dātiya-, Achaemenid Elamite: Da-ti-ya) was a Median noble and admiral who served the Persian Empire during the reign of Darius the Great (522–486 BC). He is known for his role in leading the Persian amphibious expedition against Greece in 490 BC during the Greco-Persian Wars. Along with Darius's nephew Artaphernes, he was tasked with subduing Eretria and Athens, succeeding the previously defeated Mardonius.

While some later sources claim Datis died during the Battle of Marathon (490), this is not corroborated by other evidence. His later career is largely unknown except that his sons served as cavalry leaders under Xerxes I (486–465 BC). Datis was familiar with Greek affairs, maintained connections with Greek officials, respected Greek deities, and even attempted to speak Greek.
