If you've read anything on Charles I, there was no way he was going to roll over for the January 6th committee that tried him, and condemned him to death. He firmly believed, as had British monarchs that had gone before him, that they had a divine right to rule, given to them by God. He died believing that.

All correct.
Watched a few videos on Charles I on YouTube after the Queen passed. Because of Prince Charles.

I've got an excellent book about the trial, execution and burial of Charles I. It's titled: "O Horrable Murder" by Robert B. Partridge. There is also the book titled: "The King's Revenge: Charles II and the Greatest Manhunt in British History" by Don Jordan and Michael Walsh. Not sure if this is available online for viewing, or if you've already been able to watch it, but this documentary series is also very good:
