Sub question 4: What were Tutankhamen's achievements in developing ancient Egypt? What impact did he have on his society and culture?:
Tutankhamen was a young pharaoh who did not have a lot of time to make a significant impact on developing ancient Egypt. Nonetheless, he did have some achievements that are worth noting.
One of his most significant achievements was the restoration of the traditional Egyptian religion after his predecessor Akhenaten's reign, where the monotheistic worship of the sun disk Aten was imposed. Tutankhamen reversed that decision and returned to the traditional polytheistic religion. He also restored the priesthood and the practices and rituals of the ancient gods.
Tutankhamen also initiated some building projects during his reign, including the completion of his tomb in the Valley of the Kings, which was discovered almost intact by archaeologist Howard Carter in 1922. Tutankhamen's tomb contained a vast amount of treasure and artifacts that provided invaluable insights into ancient Egyptian society and culture.
However, because of his short reign and young age at death, Tutankhamen did not have a substantial impact on shaping ancient Egypt's culture and society. Still, his restoration of the traditional religion and his tomb's discovery allowed the world a unique glimpse into the civilization's achievements and the way of life at that time.
