What is known about King Tut's life and death?

Tutankhamen was the son of Amenhoptep IV (who changed his name about five years into his reign to Akhenaten) and a lesser wife Kiya.  Akhenaten ruled from 1350-1334 B.C.E. During that time he was responsible for a revolutionary break with the ordered religious beliefs of the ancient Egyptian pantheon, instituting the monotheistic belief in the Aten. Egyptian society was turned inside out upon his decree. Akhenaten moved the capital from Thebes to the new city of Armana. In the past the temples' innner sanctuaries were off limits to the common people, however Akhenatan opened them to the public.  These actions caused considerable concern among the priests and military elite.  From their perspective the pharoah's actions were irresponsible and could be destructive to the nation. Akhenaten died about 17 years into his reign. Since Nefertari's children were all female the throne passed to Akhenaten's son from a lesser wife.  Due to his young age historians and archaeologists alike agree that the visier Ay and the general of the army Horemheb groomed the young prince for his future. If they could dismantle all of Akhenaten's decrees, reinstitute the old religious practices in the name of the boy king all would be well. There is little doubt that these policies came from Ay and Horemheb in the name of Tutankhamen, which by the way was changed from Tutankhaten to Tutankhamen by Ay and Horemheb..

Tut died when he was about 18 or 19 years old.  Howard Carter's discovery of King Tut is the only one to date that was found in tact in The Valley of the Kings.  Archaeologists use the tomb as a sort of measure...for example, if this wealth was found in Tut's tomb...a minor king....what possible treasures could have been in the other tombs such as Ramses II etc.  The ancient Egyptians believed in life after death, immortality...they were the first resurrectionists...and when you really think about it, King Tutankhamen's legacy is definitely one of immortality. The minor king of a heretic pharoah is more well known in our present reality than he was ever known is his own.
