Amenhotep IV he 1 ruled for the first five years
maintaining religious policies and traditions just like
his father. However, in his fifth year on the throne, he
underwent a profound religious transformation and
shifted his devotion from the cult of the god Amun to
the cult of the sun god Aten, disk of the sun, most
likely a symbolic grouping of the symbol of Ra. Over
the next 12 years, he brought about a fundamental
religious transformation, abolishing the traditional
religious rites of Egypt, primarily the cult of Amon.2,
and instituted the world's first known state,
monotheistic religion and, according to some,
monotheism itself.
