Gustave corbet became the leader for a new art: history painting about real life. he believed that if he could not see something, he should not paint it. he also decided that his art should have a social consciousness that would awaken the self-involved parisian to contemporary concerns: the good, the bad and the ugly.

The answer is realism.

Explanation:

As the paragraph says, realism attempts to represent a subject in a true, non-artifcial way. In other words, it avoids any unlikely or supernatural elements. It is also known as naturalism.

Although Gustave Courbet was seen as the leader of realism in his time, realism is arguably a matter of technique and not a period in art history.
