I read a book in the early nineties about a young man who becomes a king in a medieval setting, lots of drama and backstabbing. I can remember that it was part of a series, most likely a trilogy. I can’t even remember if it was fictional Europe or just some unnamed land. I don’t remember there being any magic or fantasy elements. Also I feel like this book was written in the early 90s as I remembering reading the novel as a brand new book in 91/92. In most of the novel the main protagonist is a young man. Can anyone help?
Although I don't remember it having magic or fantasy elements, it definitely was either alternate history or just an non-Earth world. It's possible that it was a low-magic setting.
