Kushites of Kishites were an Afro-Asiatic mountain people of Mesopotamia from whom came Nimrod. Their first king was Etanna who reigned immediately after the end of Ice-Age deluges which submerged many costal communities. They left their name in mountainous areas from the Caucasus to as far as Afghanistan. According to some scholars they eventually migrated around the Oman & Yemen coasts of Punt to Ethiopia in the 4th Millennium BC after being displaced by the Sumerian-speaking Asshur-Shemites from the east.
