Actually Had Significant Accomplishments
Tutankhamun's reign is typically regarded as lacking in accomplishments because he passed away at the comparatively young age of 19, and because his primary claim to fame occurred so many years after his passing. But he went far further in mending the religious rifts, pleasing all the doubters of the idea of putting a nine-year-old in charge by bringing back the ancient religion and returning the nation's capital to Memphis. The Medinet Habu temple, the temple at Karnak, and the expansion of the temple at Soleb were all ordered by him after he rebuilt the outdated temples and statues and sufficiently stabilized the economy.
The enormous, relatively unharmed monument that still stands in the temple at Medinet Habu stands out in particular. These may appear specialized, but given the conditions of his ascent to power, they had an impact on Egyptian society long after Tut was gone. He was prepared to hear reason when necessary, despite the fact that his actions were also partly the result of the advice he received from people like General Horemheb and Vizier Ay.
