Thutmosis the Long-Lived

Under Thutmosis III, Egypt had reached it's maximum splendour. Thutmosis III was one of the greatest pharaohs of Egyptian history. He campaigned into Syria, Palestine and Nubia, and even trespassed the Mitanni kingdom, weakening it considerably in favour of the Egyptians, Babylonians and Hittites. He died in 1425, 54 years into his reign, when he was planning another campaign into Nubia. What if that hadn't happened, and he had died at 1400, 79 years into his reign?

Thutmosis' Nubian Campaigns
Thutmosis led a Nubian campaign in 1429, defeating the Kingdom of Kerma all the way into the Egyptianized Fourth Cataract of the Nile. He was weakened by a sickness on the campaign, and had to return to Thebes. However, the sickness didn't kill him, and on 1423 he led another campaign into Kerma.
