Halys River in the context of "Median state"

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.

Hattusa, also Hattuşa, Ḫattuša, Hattusas, or Hattusha, was the capital of the Hittite Empire in the late Bronze Age during two distinct periods. Its ruins lie near modern Boğazkale, Turkey (originally Boğazköy) within the great loop of the Kızılırmak River (Hittite: Marashantiya; Greek: Halys).

French archeologist Charles Texier brought attention to the ruins after his visit in 1834. Over the following century, sporadic exploration occurred, involving different archaeologists. The German Oriental Society and the German Archaeological Institute began systematic excavations in the early 20th century, which continue to this day. Hattusa was added to the UNESCO World Heritage Site list in 1986.

If Herodotus' story is accurate, the Medes were unified by a man named Deioces, the first of the four kings who would rule the Median Empire; a mighty empire that included large parts of Iran and eastern Anatolia.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 BC), 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 an area of 2.8million 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 BC) 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 BC, the Median capital, Ecbatana, was conquered by the Persian king Cyrus II, marking the beginning of the Achaemenid empire.While it is generally accepted that the Medes played a significant role in the ancient Near East after the fall of Assyria, historians debate the existence of a Median empire or even a kingdom. Some scholars accept the existence of a powerful and organized empire that would have influenced the political structures of the later Achaemenid empire. Others argue that the Medes formed a loose confederation of tribes rather than a centralized state.

Paphlagonia (/ˌpæfləˈɡoʊniə/; Greek: Παφλαγονία, romanized: Paphlagonía, modern translit. Paflagonía; Turkish: Paflagonya) was an ancient region on the Black Sea coast of north-central Anatolia, situated between Bithynia to the west and Pontus to the east, and separated from Phrygia (later, Galatia) by a prolongation to the east of the Bithynian Olympus. According to Strabo, the region was bounded by the river Parthenius to the west and the Halys River to the east. Paphlagonia was said to be named after Paphlagon, a son of the mythical Phineus.

The Chalybes (/ˈkælɪbiːz/; Ancient Greek: Χάλυβες/Χάλυβοι; Georgian: ხალიბები) and Chaldoi (Ancient Greek: Χάλδοι; Armenian: Խաղտիք, romanized: Xałtik') were peoples mentioned by classical authors as living in Pontus and Cappadocia in northern Anatolia during Classical Antiquity. Their territory was known as Chaldia, extending from the Halys River to Pharnakeia and Trabzon in the east and as far south as eastern Anatolia. According to Apollonius of Rhodes, the Chalybes were Scythians.

The Chaldoi, Chalybes, Mossynoikoi, and Tibareni, are counted among the first ironsmith nations by classical authors. Χάλυψ, the tribe's name in Ancient Greek, means "tempered iron, steel", a term that passed into Latin as chalybs, "steel". Sayce derived the Greek name Chalybe from Hittite Khaly-wa, "land of Halys River". More than an identifiable people or tribe, "Chalybes" was a generic Greek term for "peoples of the Black Sea coast who trade in iron" or "a group of specialised metalworkers".

Lud (Hebrew: לוּד Lūḏ) was a son of Shem and grandson of Noah, according to Genesis 10 (the "Table of Nations").

The descendants of Lud are usually, following Josephus, connected with various Anatolian peoples, particularly Lydia (Assyrian Luddu) and their predecessors, the Luwians; cf. Herodotus' assertion (Histories i. 7) that the Lydians were first so named after their king, Lydus (Λυδός). However, the chronicle of Hippolytus of Rome (c. 234 AD) identifies Lud's descendants with the Lazones or Alazonii (names usually taken as variants of the "Halizones" said by Strabo to have once lived along the Halys) while it derives the Lydians from the aforementioned Ludim, son of Mizraim.
