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.

Not same period as John Adams but Chernobyl Is amazing

Chief of War is fantastic. Historical drama based on Hawai’i’s timeline during the 1800s when the west found the island. It’s a bit brutal at times (especially the first episode) and it’s a lot of subtitles but it’s so well done. Jason Momoa’s best.

The Crown is also some of the best TV and acting out there. Absolutely excellent drama based on the Elizabeth II’s years. It’s incredible. Best John Lithgow acting hands down.

It’s not the same fictionalization, but I really, really, highly recommend everything ever put out by PBS American Experience. Everything.

TURN =George Washington’s Spies.
