Why was Hatshepsut wealthy?

In terms of trade, Hatshepsut was not blind to the need of bolstering Egypt's economy' and indeed, the Punt expedition is but the climax of her consistent trading enterprises with Lebanon, Crete, Syria, West Africa, South Africa, Aswan and the reopening of mines in Mt. Sinai. She traded Ivory, gold, silver and other goods for eating. Hatshepsut's legacy is also extant in the enduring architectural innovations she incorporated into her building program. The design of Djeser-Djeseru is a prime example; although there exist a few doubtful precursors of the terraced template originality of the design cannot be gainsaid.' The thematic structure of the three terraces, from her role as pharaoh, to legitimization of her rule and achievements, to the worship of the deities is indisputably her own invention, as were the ramps linking them, imitating the glory of a sun's ray. Thutmose III modeled his mortuary temple on Hatshepsut's whilst Akhenaten incorporated the design of the ramps into his own buildings. Similarly, the design of Hatshepsut's tomb, with the three successive passageways leading to the burial chamber, her royal sarcophagus, her resting stations for Amun's barque were likewise replicated by her successors. Therefore, Hatshepsut's reign was characterized by a myriad of architectural innovations that became her legacy, to be admiringly integrated into the buildings of the future generations of pharaohs.
