Religion in Animal Farm is used, as Karl Marx famously said, as an "opiate of the masses." The animals are distracted from their horrible living situation and life of labor with visions of "Sugarcandy Mountain," a supposed heaven. Religion is also peripherally associated with corrupt power. The government tolerates religion precisely because of its ability to placate and to distract the lower-class animals. Yet religion is also the only thing that makes the animals’ lives seem worth living as their situation becomes increasingly miserable.
Although relatively little text time is devoted to Moses the raven, the theme of religion is constantly present in Napoleon's regime.
Although they play very different roles, Moses and Napoleon derive power and interact with the other animals in similar ways, making clear a connection between dictatorship and religion.
