Best historical fiction?

I am 50 pages away From finishing the Count of monte Cristo and I anticipate what's probably the biggest post-novel depression I'll ever receive. Please help me

I've only recently begun reading historical fiction as I mostly read Sci fi and fantasy. The only other historical novels I've read were a thousand splendid suns(Does this count? It did end around the early 2000's) and all quiet on the western front.

My requirements are basically well written / deep /likeable characters. Don't have to be likable, just deep and well written. I would love good "world building", for lack of a better word. E.g. Like the count of monte Cristo paints a great picture of 19th century France, the places, society etc. A thousand splendid suns created a vivid picture of Afghanistan in the late 20th century.

I have considered the 3 musketeers or the kite runner, but I crave a bit diversity and would like something different from what I've read

I hesitate to say I would like ones about real people, because I would love a novel structured like a story, not an autobiography/biography. But despite that I LOVED movies and TV based on real people /events like Chernobyl, Narcos, Oppenheimer and Schindlers list which got me into reading historical fiction in the 1st place

If it matteres/helps suggestions, my favourite Scifi/fantasy was :LOTR, stormlight archive, Hyperion and The expanse
