Why did kushites become allies with hyksos?

The Kushites became allies with the Hyksos primarily due to shared interests in trade and military support during a time of instability in Egypt. The Hyksos, having invaded and taken control of parts of Egypt, sought alliances to strengthen their position, while the Kushites aimed to enhance their own power and influence in the region. This alliance allowed both groups to benefit from each other's resources and military capabilities, facilitating trade and providing mutual protection against common enemies.
