14th century BC in Egypt

Dynasty of Egypt between 1550 BCE and 1295 BCE, notably comprising Akenaten and Hatshepsut

Atenism, also known as the Aten religion, the Amarna religion, and the Amarna heresy, was a religion in ancient Egypt. It was founded by Akhenaten, a pharaoh who ruled the New Kingdom under the Eighteenth Dynasty. The religion is described as monotheistic or monolatristic, although some Egyptologists argue that it was actually henotheistic. Atenism was centered on the cult of Aten, a god depicted as the disc of the Sun. Aten was originally an aspect of Ra, Egypt's traditional solar deity, though he was later asserted by Akhenaten as being the supreme of all deities.
