Which artistic movement was most dedicated to fighting social injustice?

Answer 1

Social Realism (aka Socio-Realism) was most dedicated to fighting social injustice. This movement was the most prominent during the Great Depression in the 1930s. The Social Realism focused on the working-class, especially the poor, to highlight the appalling realities of the then contemporary life. Social Realists captured what they saw without any embellishments to send a message rather than focusing on style or aesthetics.
