Final answer:
Trade played an important role in the relationship between Egypt and the Kingdom of Kush, as Egypt provided luxury goods and both kingdoms maintained peaceful relations through diplomatic alliances.
Step-by-step explanation:
Trade played a significant role in the relationship between Egypt and the Kingdom of Kush. The Kingdom of Kush was economically dependent on Egypt, as Egypt provided luxury goods like ivory, enslaved peoples, perfume, exotic animals, and hardwoods to Kush. This trade relationship facilitated diplomatic alliances between the two kingdoms as they exchanged gifts and maintained peaceful relations. Despite the Egyptian belief of superiority, they actively traded with Kush and other neighboring civilizations, spending more time trading and sending gifts than waging war.
