Kadashman-Enlil I and Burnaburiash II

The next period of Babylonian history for which we have limited information is the 14th century BC There was a discovery at Amarna in Egypt of a cache of clay tablets inscribed in cuneiform, which has shed considerable light on this time period. These tablets contain letters to the Egyptian pharaohs (Tuthmosis III to Amenophis IV) from various parts of the Fertile Crescent, including Babylonia. The letters were written in Akkadian, which had been the language of international relations for some time. [Middle Babylonian Period] Bible History Online
