The Amarna letters were recovered from the royal archives in El Amarna, where they appear to have been archived after having been translated for the royal court. The letters are inscribed on clay tablets in Cuneiform, the dominant form of writing in Mesopotamia, Canaan, and the neighboring cultures in Anatolia and Cyprus at the time. The shape of the Cuneiform logograms used is Akkadian, the parent form of the later Neo-Babylonian, Neo-Assyrian, and Ugaritic forms of Cuneiform, however, the language used in the Letters is not pure Akkadian. The Letters are between various members of the Egyptian royal court, and many different cities and nations across the Middle East, including Babylon, Assyria, Mitanni, and Cyprus, and therefore the language within the Letters is not consistent. Within the letters from Canaanite cities, all of which were subject to Egypt at the time, several transliterated names are also used, which appears to be a direct precursor to the later development of Ugaritic Cuneiform by 1200 BC, which was an abjad similar to the Canaanite script that was developed by 1000 BC, however, used Cuneiform logograms instead of alphabet-like letters.
The surviving letters were mostly about trade and diplomacy, however, do include a great deal of information about what was happening in the Middle East at the time. In particular, they demonstrate how limited Egypt's actual control of its Canaanite holdings was, where the governors of cities were constantly requesting military help to defend themselves against each other, the marauding Habirus, and the Hittite-backed Amorites in northern Canaan. The Amarna Letters were written during the mid-1330s BC, during the reigns of the Pharaohs Amenhotep III and Akhenaten, although it is not always clear when in their respective reigns the letters were written, or even which pharaoh was on the throne at the time.
