I was interested in the Vikings and Scandinavian history a few years back. I read a selection of things that were Viking histories and English histories that pertained to the Vikings. As far as Egyptian history I read a few egyptian history book my university has and I also read a book called Religion and Magic in Ancient Egypt by Rosalie David. It traced the history of Egyptian faith practices from the civilization's beginning through its growth into an empire and its later years as a Roman province. And for the Latin American Civilizations and feudal japan i cant help you there. Also, check out the History subreddit's reading list https://www.reddit.com/r/history/wiki/recommendedlist
