2nd millennium BCE in the context of "Code of Hammurabi"

Dodona (/doʊˈdoʊnə/; Doric Greek: Δωδώνα, romanized: Dōdṓnā, Ionic and Attic Greek: Δωδώνη, Dōdṓnē) in Epirus in northwestern Greece was the oldest Hellenic oracle, possibly dating to the 2nd millennium BCE according to Herodotus. The earliest accounts in Homer describe Dodona as an oracle of Zeus. Situated in a remote region away from the main Greek poleis, it was considered second only to the Oracle of Delphi in prestige.

Aristotle considered the region around Dodona to have been part of Hellas and the region where the Hellenes originated. The oracle was first under the control of the Thesprotians before it passed into the hands of the Molossians. It remained an important religious sanctuary until the rise of Christianity during the Late Roman era.

Vedic Sanskrit, also simply referred as the Vedic language, is the earliest attested form of the Sanskrit and Prakrit languages: members of the Indo-Aryan subgroup of the Indo-European language family. It is attested in the Vedas and related literature compiled over the period of the mid-2nd to mid-1st millennium BCE. It is orally preserved, predating the advent of writing by several centuries.

Extensive ancient literature in the Vedic Sanskrit language has survived into the modern era, and this has been a major source of information for reconstructing Proto-Indo-European and Proto-Indo-Iranian history.

Enkidu (Sumerian: 𒂗𒆠𒄭 EN.KI.DU₁₀) was a legendary figure in ancient Mesopotamian mythology, wartime comrade and friend of Gilgamesh, king of Uruk. Their exploits were composed in Sumerian poems and in the Akkadian Epic of Gilgamesh, written during the 2nd millennium BC. He is the oldest literary representation of the wild man, a recurrent motif in artistic representations in Mesopotamia and in Ancient Near East literature. The apparition of Enkidu as a primitive man seems to be a potential parallel of the Old Babylonian version (1300–1000 BC), in which he was depicted as a servant-warrior in the Sumerian poems.

There have been suggestions that he may be the "bull-man" shown in Mesopotamian art, having the head, arms, and body of a man, and the horns, ears, tail and legs of a bull. Thereafter a series of interactions with humans and human ways bring him closer to civilization, culminating in a wrestling match with Gilgamesh, king of Uruk. Enkidu embodies the wild or natural world. Though equal to Gilgamesh in strength and bearing, he acts in some ways as an antithesis to the cultured, city-bred warrior-king.

The ancient Middle Eastern state of Mitanni (modern-day Northeast Syria, Southeastern Turkey, 2nd millennium BCE) used a dialect of Hurrian as its main language. This dialect however contains some loanwords of evidently Indo-Aryan origin, i.e. related to Sanskrit, the ancestor of many modern languages of the Indian subcontinent. The loaned vocabulary seems to be related to an elite group in Mitanni society, as they appear in the names of rulers and gods as well as in relation to horse-breeding and the military (thus forming a so-called superstrate).

It is thus generally believed that Indo-Aryan peoples settled in Upper Mesopotamia and northern Syria, and established the kingdom of Mitanni following a period of political vacuum, while also adopting Hurrian. This is considered a part of the Indo-Aryan migrations.
