The modern leader is most like Akhenaten could be the actual Catholic Pope Francis or Francisco. Here is the reason why.
Akhenaton was a controversial ancient Egyptian Pharaoh that created so much confusion in his time as Egyptian ruler because he changed the polytheist's approach of the Egyptian gods and imposed the belief of one deity, the God Aton, the God Sun. This was a controvert decision and people did not like him. Indeed, he was practically erased from Egyptian history.
