The nature of the question is quite broad in its scope. I think that using Animal Farm in comparison to Orwell's other work of political critique, 1984, can reveal some interesting elements. Both work make distinct and strongly passionate claims against a centralized authority that has no checks or limitations to its power. Both works construct a strong statement against the ways in which authority silences individual voices. This becomes a critical issue in both works. Both works detail what happens when individuals seek to challenge an authority structure without a large following behind them. Winston and Snowball both end up failing in their attempts to either outwardly challenge the authority structure or even try to offer another competing notion of the good. In both works, the use of propaganda is critical in keeping the citizenry in an obscure manner about what is being done in its name. The citizens of Oceania and the Animals on the farm do not really know and do not really have any awareness of what is being done in their name and are kept in direct ignorance about issues. Through these comparisons, one can see how both works are similar to one another, using Orwell's 1984 as a work of comparison to Animal Farm.
