Gulliver's Travels is a satirical novel by Jonathan Swift, published in 1726. It follows the voyages of Lemuel Gulliver and can be analyzed through the theme of colonialism. The novel is divided into four parts where Gulliver visits four different lands and faces struggles as both a colonizer and colonized. Swift uses these voyages and Gulliver's experiences to critique greed, selfishness, and flaws in human nature. The theme of colonialism, with its power dynamics between colonizers and colonized, helps to understand the plot and social commentary within Gulliver's voyages.
