I think you are looking for TV shows about historical figures and eras, not fiction set in a historical period.
All the Light We Can Not See: It tells the story of Meir Giess. She was one of the people who supported and hid Anne Frank and her family.
King and Conquerer: It is about the Norman invasion of England. It is very good but it seems it is not historically accurate.
Marco Polo: It is about Marco Polo’s time in Asia. The story is dull and muddled but it looks amazing and so many of the cast are incredible. It is worth the watch just for the character 100 eyes and Benedict Wong as khan. Wong’s performance is one of the GOATs
Victoria: It is a show about Queen Victoria’s early life.
