Yes, it is. The Tudors takes inspiration from real historical events and figures of the Tudor dynasty, but there are some fictional elements for dramatic effect.
To some extent. The show takes inspiration from actual history but also incorporates fictional elements and creative interpretations for dramatic effect.
Another good one is 'Bring Up the Bodies' by Hilary Mantel. It's a sequel to 'Wolf Hall'. It continues the story of Thomas Cromwell and the Tudor court. Mantel's research and writing style make it a must - read for anyone interested in the Tudors. You get to see more of the political intrigue and the personalities at court.
Ken Follett's 'The Pillars of the Earth' has elements related to the Tudors. While it's mainly about the building of a cathedral, it also touches on the social and political upheaval of the time, which was very much influenced by the Tudors. It's a long but engaging read that shows how the Tudor period affected different aspects of society.
I'm not entirely sure specifically what 'Showtime 1996 Bedtime Stories' is about. It could be a collection of bedtime stories presented in 1996 on Showtime. Maybe it features various fictional tales for kids to listen to before going to sleep.
To be honest, I don't have a definite answer. Sometimes shows take elements from real life and fictionalize them. It's hard to say for this one without more information.
