How did Thutmose III expand Egyptian rule in Nubia?

Thutmose III expanded and solidified Egyptian rule in Nubia by initiating a truly imperial administration that transformed the region into a source of wealth and resources for Egypt. His approach involved several key strategies:1

• Military Subjugation: He thoroughly subdued turbulent local tribes and reaffirmed the southern boundary of Egyptian control as far as Kurgus.2
• Administrative Integration: Existing Nubian fortresses were repurposed as administrative centers, around which open towns developed. He established the cult of the divine king in temples built outside these fortresses.1
• Cultural Assimilation: Sons of local chiefs were brought to the Egyptian court to be educated, ensuring they returned to Nubia as loyal, Egyptianized administrators.12
• Economic Exploitation: The region became a vital source of gold, which fueled Egypt's foreign exchange, as well as tropical goods such as ivory, animal skins, ostrich plumes, oil, perfumes, and wood.12
• Religious Infrastructure: He founded a new Nubian capital at Napata and constructed a temple to Amon near Mount Barkal.12
