which new kingdom pharaoh outlawed the worship of many gods and established a new religon with one, all-powerful god

Answer: Akhenaten

Akhenaten, previously known as Amenhotep IV was a pharaoh from the 18th dynasty that ruled Egypt for 17 years. He is famous for trying to move from the polytheistic traditional religion of Egypt to a monotheistic one, centered on the Aten, a solar deity.

He is also famous as husband of Queen Nefertiti and father of King Tutankhamun. His attempt at cultural change was not well-received in Egypt, and after his death, his monuments were destroyed and his name deleted from the record of kings.
