Religion is a big part of revolutions. More specifically, it seems that there is a certain level of faith necessary to exist in resistance movements. Resistance movements like abolitionism in the ante-bellum period, the Civil Rights Movement, and liberation theology (which arrived in many South American countries during authoritarian government rule) all relied heavily on Christian interpretations. Without a basis of faith, most resistance movements would crumble. There wouldn’t be a reason greater than the government they face to fight for. In order for dystopias to be toppled, people have to agree that there is some cause greater than the power of the dystopian government. Religion is often one of the most powerful reasons that people take up arms against a government. It is a primary motivator; governments understand this, hence the suppression of religion in communist (and often authoritarian) governments and the Party in 1984.
