Most people kind of merge the kingdoms together, while every kingdom is unique in both the culture and, say, external influence. And the late period is quite long as well.

There is a very strong connection between periods, of course. But 2500+ years of ancient egypt is a very long damn time. All of our modern history is, say, 3k years, starting with greeks, early chinese , india and all.

But egypt to me is like a star in the vast ocean of nothingness of early history. We know NAMES and DEEDS of people who lived 4500 years ago. We see things they've built, we can read words they wrote.

This is amazing.
