It is believed that Shakespeare wrote Macbeth with what king in mind And why?

Macbeth was probably written as a tribute to king James. There are 3 main evidences of this; first: setting. This play is set in Scotland,the land of king James' ancestors. Second,one of the main theme of this play is witchcraft. King James was really interested in this topic: he wrote a book about it in 1597 (Demonology). Last but not least, Shakespeare put Banquo in the line of kings. Banquo really existed and he was related to king James.
