I came across an article titled “In Light of Cush/Kush the Dark” ‘The Cushites Who Overthrew Ancient Egyptians’ By Gregory V. Boulware. At inlightofkushthedark.blogspot / and https://boulwareenterprises.wordpress.com/2015/03/24/in-light-of-cushkush-the-dark/
I would like to express the findings of my own research for 30 years; I also posted them on my English and Arabic blogs with many diagrams. https://tariganter.wordpress.com and https://tarig2.wordpress.com
Kush, not Cush, appeared with this name in around 780 BC before that it was a nameless coalition of Hyksos stranded in Libya in 1523 BC, who were 90% Amorite of Levant on foot and 10% Turkic Mongolian Akkadians of East Asia on horses.
The stranded Hyksos in Libya sought two ways to connect with the expelled Hyksos who fled mostly to the East forming Hebrews, Kassites, Mitanni and Mukarribs. These bandits renamed themselves after the Battle of Carchemish in 605 BC to Jews, Babylonians, Kurds and Sabaeans
By sea, some of the Hyksos in Libya crossed to Anatolia and took part in the Trojan wars and the events leading to the Late Bronze Age Great Collapse. However, the main alternative route was on land.
The stranded Hyksos in Libya allied with Berber bandits and invaded West Africa collecting mercenaries and slaves. That formed the Fulani conglomerates. The mixed bandits of Hyksos-Berber-Fulani started invading and colonizing the kingdoms of the Southern Nile Valley, coming first from what is now called Darfur.
The Hyksos-Berber-Fulani bandits created a colony and called it Kordofan in 1450 BC. The bandits grew bigger and stronger and continued to attack Kerma kingdoms along the six Cataracts threatening the first half of the 18th Dynasty of Kmt that expelled the Hyksos. Kmt noticed the threats and protected Kerma
Starting with Thutmose III, the opponent of Queen Hatshepsut, the second half of the 18th Dynasty reversed Kmt’s policies. Suddenly, Kmt under Thutmose III and who followed him deliberately ignored the protection of Kerma. They allowed the bandits of Hyksos-Berber-Fulani to colonize up the Fourth Cataract. The 19th Dynasty ended that treason and resumed the protection of Lower Kerma strongly and directly.
After the fall of the 20th Dynasty which ended the New Kingdom of Kmt in 1070 BC, the nameless mixed bandits of Hyksos-Berber-Fulani invaded, revenged and colonized Lower Kerma with vicious brutality ending indigenous rule in Kerma and its neighbors in 1000 BC
All Kerma and surrounding regions remained in a dark and lawlessness period of 220 years full of banditry raids, slavery, looting, and chaos made by small-scattered bandits of Hyksos-Berber-Fulani. When the 24th Dynasty in Kmt defeated and expelled the 22nd and 23rd regimes of Hyksos origin that triggered great fear and worries among the bandits colonizing Kerma and neighborhood.
The Hyksos-Berber-Fulani bandits came under one warlord and declared their colony a kingdom and called it Kush or Kus. The name was a variation borrowed from Cush, which is a clan from Noah in southern Punt Lands. The main reason to create Kush was to invade Kmt and give fast support for the defeated Hyksos in Ugarit who after the 24th Dynasty defeated and expelled them they came under further attack from the the Assyrian Empire
Kush was only colony for the Hyksos-Berber-Fulani coalition against Kerma, Kmt, and Punt. Kush fought against the nations of Ugarit, Ebla and Sumer.
