Thankful for suggestions!
Check out our booklist! Especially a shoutout to /u/uncovered-history who has recently done some major overhauls there.
Sorry for the delay! Our booklist is great, however if you want something a bit more personalized, I will be happy to make personal recommendations.
What are you hoping to learn about? Politics, the army, battles, religion, the economy? Perhaps just a general history or maybe study one of the dominating figures of the period?
