Old Persian in the context of "Darius the Great's Suez Inscriptions"

Media (Old Persian: 𐎶𐎠𐎭 Māda; Greek: Μηδία Mēdía; Akkadian: Mādāya) was a political entity centered in Ecbatana that existed from the 7th century BCE until the mid-6th century BCE and is believed to have dominated a significant portion of the Iranian plateau, preceding the powerful Achaemenid Empire. The frequent interference of the Assyrians in the Zagros region led to the process of unifying the Median tribes. By 612 BCE, the Medes became strong enough to overthrow the declining Assyrian empire in alliance with the Babylonians. However, contemporary scholarship tends to be skeptical about the existence of a united Median kingdom or state, at least for most of the 7th century BCE.

According to classical historiography, Media emerged as one major power of the ancient Near East after the collapse of Assyria. Under Cyaxares (r. 625–585 BCE), the kingdom's borders were expanded to the east and west through the subjugation of neighboring peoples, such as the Persians and Armenians. Media's territorial expansion led to the formation of the first Iranian empire, which at its height would have exercised authority over more than two million square kilometers, stretching from the eastern banks of the Halys River in Anatolia to Central Asia. In this period, the Median empire was one of the great powers in the ancient Near East alongside Babylon, Lydia, and Egypt. During his reign, Astyages (r. 585–550 BCE) worked to strengthen and centralize the Median state, going against the will of tribal nobility, which may have contributed to the kingdom's downfall. In 550 BCE, the Median capital, Ecbatana, was conquered by the Persian king Cyrus II, marking the beginning of the Achaemenid empire.

Lydia (Ancient Greek: Λυδία, romanized: Ludía; Latin: Lȳdia) was an Iron Age kingdom situated in western Anatolia, in modern-day Turkey. Later, it became an important province of the Achaemenid Empire and then the Roman Empire. Its capital was Sardis.

At some point before 800 BCE, the Lydian people achieved some sort of political cohesion, and existed as an independent kingdom by the 600s BCE. At its greatest extent, during the 7th century BCE, it covered all of western Anatolia. In 546 BCE, it became a satrapy of the Achaemenid Empire, known as Sparda in Old Persian. In 133 BCE, it became part of the Roman province of Asia.

Persian, also known by its endonym Farsi or Parsi, is a Western Iranian language belonging to the Iranian branch of the Indo-Iranian subdivision of the Indo-European languages. Persian is a pluricentric language predominantly spoken and used officially within Iran, Afghanistan, and Tajikistan in three mutually intelligible standard varieties, respectively Iranian Persian (officially known as Persian), Dari Persian (officially known as Dari since 1964), and Tajiki Persian (officially known as Tajik since 1999). It is also spoken natively in the Tajik variety by a significant population within Uzbekistan, as well as within other regions with a Persianate history in the cultural sphere of Greater Iran. It is written officially within Iran and Afghanistan in the Persian alphabet, a derivative of the Arabic script, and within Tajikistan in the Tajik alphabet, a derivative of the Cyrillic script.

Modern Persian is a continuation of Middle Persian, an official language of the Sasanian Empire (224–651 CE), itself a continuation of Old Persian, which was used in the Achaemenid Empire (550–330 BCE). It originated in the region of Fars (Persia) in southwestern Iran. Its grammar is similar to that of many European languages.

The Iranian languages, or the Iranic languages, are a branch of the Indo-Iranian languages in the Indo-European language family that are spoken natively by the Iranian peoples, mainly in the Iranian Plateau.

The Iranian languages are grouped in three stages: Old Iranian (until 400 BCE), Middle Iranian (400 BCE – 900 CE) and New Iranian (since 900 CE). The two directly attested Old Iranian languages are Old Persian (from the Achaemenid Empire) and Old Avestan (the language of the Avesta). Avesta predates Old Iranian language, Old Avestan (c. 1500 – 900 BCE)[8] and Younger Avestan (c. 900 – 400 BCE).[9] Of the Middle Iranian languages, the better understood and recorded ones are Middle Persian (from the Sasanian Empire), Parthian (from the Parthian Empire), and Bactrian (from the Kushan and Hephthalite empires).

Akkadian (/əˈkeɪdiən/ ə-KAY-dee-ən; Akkadian: 𒀝𒅗𒁺𒌑(𒌝), romanized: Akkadû(m)) is an extinct East Semitic language that is attested in ancient Mesopotamia (Akkad, Assyria, Isin, Larsa, Babylonia) from the mid-third millennium BC until its gradual replacement in common use by Old Aramaic among Mesopotamians by the 8th century BC.

Akkadian, which is the earliest documented Semitic language, is named after the city of Akkad, a major centre of Mesopotamian civilization during the Akkadian Empire (c. 2334–2154 BC). It was written using the cuneiform script, originally used for Sumerian, but also used to write multiple languages in the region including Eblaite, Hurrian, Elamite, Old Persian and Hittite. The influence of Sumerian on Akkadian went beyond just the cuneiform script; owing to their close proximity, a lengthy span of contact and the prestige held by the former, Sumerian significantly influenced Akkadian phonology, vocabulary and syntax. This mutual influence of Akkadian and Sumerian has also led scholars to describe the languages as a sprachbund.

The manticore or mantichore (Latin: mantichorās; reconstructed Old Persian: *martyahvārah; Modern Persian: مردخوار mardḫ(w)ār) is a legendary creature from ancient Persian mythology, similar to the Egyptian sphinx that proliferated in Western European medieval art as well. It has the face of a human, the body of a lion, and the tail of a scorpion or a tail covered in venomous spines similar to porcupine quills. There are some accounts that the spines can be launched like arrows. It eats its victims whole, using its three rows of teeth, and leaves no bones behind.

Old Persian cuneiform is a semi-alphabetic cuneiform script that was the primary script for Old Persian. Texts written in this cuneiform have been found in Iran (Persepolis, Susa, Hamadan, Kharg Island), Armenia, Romania (Gherla), Turkey (Van Fortress), and along the Suez Canal. They are mostly inscriptions from the time period of Darius I, such as the DNa inscription, as well as his son, Xerxes I. Later kings down to Artaxerxes III used more recent forms of the language classified as "pre-Middle Persian".

Megabyzus (Ancient Greek: Μεγάβυζος, a folk-etymological alteration of Old Persian Bagabuxša, meaning "God saved") was an Achaemenid Persian general, son of Zopyrus, satrap of Babylonia, and grandson of Megabyzus I, one of the seven conspirators who had put Darius I on the throne. His father was killed when the satrapy rebelled in 484 BCE, and Megabyzus led the forces that recaptured the city, after which the statue of the god Marduk was destroyed to prevent future revolts. Megabyzus subsequently took part in the Second Persian invasion of Greece (480–479 BCE). Herodotus claims that he refused to act on orders to pillage Delphi, but it is doubtful such orders were ever given.

Megabates (Old Persian: *Bagapātaʰ; Ancient Greek: Μεγαβάτης Megabátēs; dates unknown) was a Persian military leader in the late 6th and early 5th centuries BC. According to Herodotus he was a cousin of Darius the Great and his brother Artaphernes, satrap of Lydia.

Based on the writings of Herodotus, Megabates is most notable for his joint participation in the failed 499 BC siege of Naxos. With Aristagoras and 200 ships, he was sent by Darius the Great to annex the small Aegean island to the Persian Empire.
