Final answer:
The discovery of King Tut's tomb in 1922 significantly impacted the worldwide treatment of antiquities, leading to enhanced preservation efforts, the reassessment of archaeological practices, and greater respect for the provenance of cultural treasures.
Step-by-step explanation:
The discovery of Tutankhamen's tomb in 1922 had profound worldwide affects on the treatment of antiquities. The discovery by Howard Carter brought ancient Egyptian civilization into the limelight and spurred on a global fascination with archaeology and history. However, the methods used during the excavation, which would be considered destructive by today's standards, highlighted the need for better preservation techniques and ethical considerations in dealing with ancient artifacts.
The nearly intact status of King Tut's tomb provided an unparalleled look into ancient Egyptian life and death practices, reinforcing the importance of these sites. This revelation pushed for changes in international policies and practices, subsequently influencing laws and norms regarding the excavation, study, and display of ancient artifacts. It also contributed to a growing awareness of the need for countries that house historical artifacts to respect the cultures from which these precious items originate, leading to repatriation efforts and stricter control over the export and display of such items. Unfortunately, issues surrounding the politics of antiquities and provenance continue to generate debate, such as the 'NefertitiHack' event, which called into question the possession and presentation of ancient artifacts in European and American institutions.
