Answer:
Nu-b-ians were able to regain their independence because they allied with Hy-k-sos, who conquered the Egypt in 1600s B. C.
Step-by-step explanation:
Nu-b-ians are an ethnic group living in the northern part of S-u-d-an and the southern part of Egypt. The early name of Nu-b-ia was K-u-s-h. In the 1600s, the king of K-u-s-h gained power by gaining much wealth and took control over the northern S-u-d-an and southern Egypt. At the same time, when Ku-sh-it-es were gaining power, Hy-k-sos conquered Egypt.
Ku-sh-ite assessing wisely to be a friend, ally or supporter of Hyksos will benefit them instead of being their enemy, joined the hands with them. And this is how Nu-bians or Ku-sh-ites were able to gain their freedom.
