Egyptian religion centered around a belief in only one god, rather than many, during the reign of which pharaoh?

The correct answer is: Akhenaten (also known as "Akhenaton" and "Amenhotep IV")

Explanation:

The pharaoh Akhenaten worshiped only the god sun, Aten, rather than following the polytheistic tradition of the Egyptian people. He even changed his own name from Amunhotep to Akhenaten, in honour of the god.

He tried to install this new system, but was largely rejected by his people. After his death, most of the works of art and architecture from his reign were destroyed and the Egyptians returned to their old religious system.
