An allegory is a work that's designed to be a metaphor for something else. Just about every character is meant to be a representation of some group or concept, and their interactions in the work are meant to convey ideas about how these groups/concepts affect each other in real life. The story may say "Alice and Bob had tea together", but in actuality, Alice represents Capitalism, Bob represents Communism, and the "tea" is actually a meeting of the UN. Expect Rule of Symbolism to come into play in these stories. Perhaps the most famous example is Pilgrim's Progress, a Christian allegory in which the protagonist (named Christian) leaves his old life to go on a journey to the Celestial City, overcoming many obstacles along the way. Not all allegories are this Anvilicious, however. Some are very subtle, to the point where you don't even realize the story is an allegory until someone points it out to you. This is why so many readers get to thinking that Everyone Is Jesus in Purgatory. World of Symbolism is a Sub-Trope in which the Allegory only makes sense on the metaphorical level and not the literal one. Allegory Adventure is a Sub-Trope in which the plot is an allegory for another work of fiction. Compare Does This Remind You of Anything?. Contrast Applicability, which is when a story has meanings beyond with the author intended. Likewise, Everyone Is Jesus in Purgatory is when the reader sees meanings that aren't really there. See Also Metaphorgotten, when the story (or reader) loses track of what it was talking about.
- Tales Of The Black Freighter, the Story Within A Story in Watchmen: a tragic little pirate story about a man who gets so paranoid about pirates attacking his home town, that he goes crazy and ends up killing everyone himself, interesting in its own right, and then you realize that It's a metaphor for the villain's plan to "save the world" by murdering thousands, and further hints that his plan is totally in vain.
