verb
denigrate
DEN-ih-grayt/ˈdenɪɡreɪt/
To criticize someone or something unfairly.
The detractor unfairly denigrates the potter’s skilled work.

Etymology
The pieces convey “completely blacken,” an image applied figuratively to staining someone's character or reputation. This reputational sense was already present in Latin and is the earliest English verb sense.
In context
he had become king by intervention of the devil, not of God. And therefore, he was not the legitimate king of France. It was all really to denigrate him, to destroy his reputation.
