The major discovery made by Howard Carter in 1922 was the tomb of Tutankhamun, an ancient Egyptian pharaoh. Located in the Valley of the Kings, this discovery was momentous because it was one of the most intact and well-preserved tombs ever found, revealing a wealth of artifacts and treasures that provided invaluable insight into ancient Egyptian culture and burial practices. The tomb included numerous items designed to accompany the pharaoh in the afterlife, such as jewelry, chariots, and the iconic gold death mask. This find reignited global fascination with ancient Egypt and significantly advanced archaeological knowledge.
