You know those kings wasn’t Egyptian?I noticed their must be some 'legacy' left over from ancient egypt in even our 'later' culture where all Somalis get emotional when they hear 'king' and respond 'only god is king', maybe their was king worship and left a legacy on us to be fearful of anything calling themselves king. Before pharoah period, ancient egyptians were knowns as KINGS even attested by the quran to differentiate the moses period and 'joseph' period the son of Jacob son of Abraham period
I’m pretty sure it’s proven they was invaders from Morden palastine and became king of Egypt until Egyptians rebelled back and changed king to pharoah.
