I know it's a super broad question but I'm writing a fantasy and I want to mix elements from these different places and time periods for the countries in my world and make a unique time period for the world. The idea being a couple of centuries after the collapse of an empire that once held the entire continent and forced everyone into their culture and afterwards there was a period of decentralized power but also the countries had a renaissance of their old cultures coming back and certain countries were more prosperous than others, some being split into smaller countries and a couple of empires forming. I'm looking for a few books for these places and time periods that could give me a good enough understanding about how people lived and the governments operated that I could actually get moving on this story. The only periods I'm even vaguely familiar with are Ancient Roman and Medieval England and France and I still know next to nothing.

The periods I'm looking for are:

Rome in the later stage of the Empire right around the collapse

Early Medieval England and France

Renaissance France

16th and 11th century BC in Egypt/The Middle East

1200-500 BC China

​

I'm interested in government structures, culture, daily life and technology.

Thanks for any info on any of these!
