The Amarna Period refers to a unique era in ancient Egyptian history during the reign of Pharaoh Akhenaten, which lasted from approximately 1353 to 1336 BCE. This period is marked by significant religious, artistic, and cultural changes as Akhenaten promoted the worship of a single deity, Aten, over the traditional polytheistic beliefs. The shift to monotheism and the establishment of a new capital at Amarna characterized this time as one of radical transformation within Egypt's New Kingdom.
