Lots of different things. Both, I think? He does a lot of movies, political satire sometimes. He's got a movie called "Blazing Saddles." Takes aim at racism in America by having a black bloke end up getting assigned as sheriff to a small town out in the west. And "The Producers" is about a pair of blokes who try to make a flop musical and end up making a hit because everyone thinks it's so bad, it must be making fun of the Third Reich and Hitler and all of the people responsible for what happened during World War II. And all of that on a meta level is aimed legitimately at making the Nazi's look as idiotic as humanly possible.
