What language manipulation causes the animals to give Napoleon the credit for all the good things accomplished on the farm?

Napoleon uses Propaganda and language manipulation through the character of Squealer, who distorts the truth and reinterprets events to promote Napoleon’s image. By consistently framing successes as a direct result of Napoleon’s leadership and decisions, Squealer reinforces the notion that he is the farm's savior. Additionally, the revision of the commandments and the celebration of Napoleon's achievements further solidify his central role in the farm's prosperity, effectively erasing any contributions from other animals. This manipulation cultivates a culture of blind loyalty and admiration for Napoleon.
