What group of people did shakespeare believe in?

Answer 1

It is very difficult to know what Shakespeare thought about anything. You cannot use what the characters in his plays say as expressions of his own beliefs.

Officially, like all English people, he belonged to the Church of England and so supported the beliefs promulgated by the Church. He also held to the position that the government that England had was absolutely just and legitimate and he supported the monarchy. If he had not held these positions he may well have ended up in prison or dead, so if he had other ideas he kept them to himself.

Answer 2

It depends on what you mean "believe in". He certainly believed in the existence of actors or he wouldn't have worked with them. He must have believed in the existence of playgoers, since he expected them to pay to see him act. He believed in the existence of Royalty, since he performed for them on a number of occasions. If you mean what group of people did he trust, well, he seems to have trusted his fellow actors and businessmen in the entertainment industry. If you mean who did he find to be credible, we don't know.
