Why did the priests become angry at akhenaton?

The priests became angry at Akhenaten because he implemented radical religious reforms that diminished the power of the traditional priesthood. By promoting the worship of Aten, the sun disk, and effectively sidelining the worship of other gods, particularly Amun, Akhenaten threatened the established religious order and the wealth and influence of the priests. This shift not only undermined their authority but also disrupted the economic and social stability that the priesthood had maintained in ancient Egyptian society.
