Many authors receive their inspiration for writing their literature from outside sources.
The idea for a story could come from family, personal experiences, history, or even their own creativity. For authors that choose to write a book based on historical events, the inspiration might come from their particular viewpoint on the event that they want to dramatize. George Orwell and Charles Dickens wrote Animal Farm and A Tale of Two Cities, respectively, to express their disillusionment with society and human nature. Animal Farm, written in 1944, is a book that tells the animal fable of a farm in which the farm animals revolt against their human masters. It is an example of social criticism in literature in which Orwell satirized the events in Russia after the Bolshevik Revolution.
