"Travels into Several Remote Nations of the World, by Lemuel Gulliver," commonly known as "Gulliver's Travels," is a satirical novel written by Jonathan Swift and published in 1726. The book is divided into four parts, each detailing Gulliver's adventures in different fictional lands.

In the first part, Gulliver finds himself stranded on the island of Lilliput, inhabited by people six inches tall. Here, he becomes embroiled in political disputes and learns about the petty squabbles among the Lilliputians.

The second part takes Gulliver to Brobdingnag, a land of giants. He serves as a plaything for the giant king while observing their society and culture.

In the third section, Gulliver visits Laputa, a flying island, and the strange lands of Balnibarbi, Luggnagg, and Glubbdubdrib. These regions introduce him to bizarre customs and intellectual pursuits.

Finally, in the fourth part, Gulliver arrives at the land of the Houyhnhnms, where horses are rational beings and humans, called Yahoos, are brutish creatures. This segment reflects Swift's critique of human nature and societal norms.

Through these fantastical journeys, Swift uses humor and irony to comment on the political and social issues of his time. "Gulliver's Travels" remains a classic work of literature that continues to provoke thought and discussion.
