The earliest references to the "four-quarters" by the kings of Akkad name Subartu as one of these quarters around Akkad, along with Martu, Elam, and Sumer. Subartu in the earliest texts seem to have been farming mountain dwellers, frequently raided for slaves.
Eannatum of Lagash was said to have smitten Subartu or Shubur, and it was listed as a province of the empire of Lugal-Anne-Mundu; in a later era Sargon of Akkad campaigned against Subar, and his grandson Naram-Sin listed Subar along with Armani, which has been identified with Aleppo,2 among the lands under his control. Ishbi-Erra of Isin and Hammurabi also claimed victories over Subar.
Three of the 14th-century BC Amarna letters – Akkadian cuneiform correspondence found in Egypt – mention Subari as a toponym. All are addressed to Akhenaten; in two (EA 108 and 109), Rib-Hadda, king of Byblos, complains that Abdi-Ashirta, ruler of Amurru, had sold captives to Subari, while another (EA 100), from the city of Irqata, also alludes to having transferred captured goods to Subari.
There is also a mention of "Subartu" in the 8th century BC Poem of Erra (IV, 132), along with other lands that have harassed Babylonia3 in Neo-Babylonian times (under Nabopolassar, Nebuchadnezzar II and Nabonidus).
Subartu may have been in the general sphere of influence of the Hurrians.4
The Sumerian mythological epic Enmerkar and the Lord of Aratta lists the countries where the "languages are confused" as Subartu, Hamazi, Sumer, Uri-ki (Akkad), and the Martu land (the Amorites). The terms referring to the language used in Subartu are known as Subarean, Subaraean or Subarian.5 To this day it is uncertain what the Akkadian and Sumerian terms for Subartu refer to and it is believed it could refer to Hurrian.6 It was also generally believed early on by experts such as Ephraim Avigdor Speiser and Arthur Ungnad that Subarean referred to Hurrian, but Ignace Gelb believes they were both independent of each other.7 Ignace also mentioned there wasn't enough evidence about Subarian.8 The evidence we have for the language are Subarian names and possibly some words that late Assyrian syllabaries said were used in Subartu.9
It was also believed at the time that the Subarian language concealed languages like Gutian and Lullubian.10 But, in the modern day, the Hurrian language is described by the Sumerians and Babylonians as Subarian11 and for modern historians, it is considered an obsolete tern similar to Mitannian.12 There is also a belief that Subarian was one of the Hurro-Urartian languages that was different from Hurrian as the Subarians established themselves earlier into Anatolia.13
Subartu (Subaru of the letters) is a toponym mentioned in the Amarna letters (14th century BC); the letters were written in the short period approximately from 1350–1335 BC. It is commonly accepted that the region referenced was Subartu.
Subartu is only referenced in three of the Amarna letters: EA 100, 108, and EA 109. All three letters state that people, or 'items' are needed to be sold in Subaru, for money.
Subaru of the letters is only referenced in three Amarna letters, and with no links to any rulers of Subaru.
The following are the letters referencing Subartu:
