The histories of Kush and Egypt are intertwined with each other because they were reliant on each other. How did their interdependence work, and why did each take control of the other in turn? \

The interdependence between Kush and Egypt can be traced back to ancient times. The region of Kush, located in what is now modern-day Sudan, first came into contact with the civilization of Egypt during the Middle Kingdom period (2055-1650 BCE). This initial contact established a long history of interaction and influence between the two kingdoms.

The main reason for their interdependence was the geographic proximity and the crucial resources each provided to the other. Egypt heavily relied on the Nile River for agriculture, trade, and transportation, and Kush controlled a significant portion of the Upper Nile region. The Nile not only provided fertile land for farming but also served as a major trade route between the two kingdoms. Furthermore, the region of Kush had valuable resources like gold, ivory, and ebony, which Egypt desired.

Initially, Egypt exerted control over Kush, treating it as a subject territory. The pharaohs of Egypt built military garrisons in strategic locations in Kush to protect their interests and maintain control over the trade routes. The Kushite rulers, while acknowledging Egyptian dominance, were allowed to rule their territory as sub-kings under the sovereignty of the pharaoh.

However, during Egypt's decline and instability in the Second Intermediate Period (1650-1550 BCE), the Kushites expanded their influence and gradually gained more autonomy. They even formed their own dynasty known as the "Fourteenth Dynasty." This period is often referred to as the "Kushite Intermezzo" or the "Kushite Rule" over Egypt.

The Kushite rule came to an end when the Egyptian pharaohs of the New Kingdom (1550-1077 BCE) regained control and expelled the Kushites from Egypt. However, despite losing political control, the Kushites still maintained strong cultural ties with Egypt. They adopted many aspects of Egyptian culture, such as art, architecture, and religion. The Kushite rulers even continued to be buried in Egyptian-style tombs.

The interdependence between the two civilizations continued to fluctuate over the centuries, with periods of conflict and collaboration. The Assyrian invasion of Egypt in the 8th century BCE weakened Egyptian control over Kush, and the Kushite kingdom began to flourish again. By the 8th century BCE, Kush had successfully reasserted its independence and even expanded its own empire, encompassing territories beyond the Nile Valley.

In the 7th century BCE, the Kushite rulers from the "Twenty-Fifth Dynasty" successfully conquered and ruled over Egypt once more. This period is known as the "Kushite or Nubian Dynasty" of Egypt. It marked a high point in the political and cultural influence of Kush over Egypt.

Ultimately, the interdependence between Kush and Egypt was driven by mutual economic and strategic interests. Both kingdoms relied on each other for resources, trade, and protection. This led to periods of control and domination by one over the other, as the balance of power shifted over time.
