Why did Kush and Egypt not get along?

Kush and Egypt often had a contentious relationship due to competition for resources and territorial control in the Nile Valley. The Kushites, located to the south of Egypt, sought to assert their power and independence, leading to conflicts over trade routes and influence. Additionally, cultural differences and political ambitions fueled rivalry, as both civilizations aimed to dominate the region. Despite these tensions, there were periods of interaction, including trade and cultural exchange.
