Answer: Swift uses imaginary lands, made-up characters, and fictional conflicts of belief.
Jonathan Swift's Gulliver Travels is written as a satire. This means that the work is meant to be a humorous social commentary. It is also a veiled critique of society, leaders and ideas of the time. The way in which Swift "masks" the real recipients of the criticism is by creating imaginary lands, made-up characters, and fictional conflicts of belief. However, the author hopes that the reader will still be able to understand who and what he is actually referring to.
