Gulliver embarks on four separate voyages in Gulliver’s Travels. There is a storm before every journey. All the four voyages add new perspectives to Gulliver’s life and also give him new opportunities for satirizing the ways of England.
In the first voyage, Gulliver travels to Lilliput, where he is huge and the Lilliputians are small. Initially, the Lilliputians look amiable, but the reader soon understands that they are very ridiculous and petty creatures. For “making water”, Gulliver gets convicted of treason in the capital (although he was putting out a fire and saving innumerable lives)–among other “crimes.”
In the second voyage, Gulliver travels to Brobdingnag, which is a land of Giants and he is as small as the Lilliputians were to him. So, naturally, Gulliver is scared, but his keepers are surprisingly gentle. He gets humiliated by the King when he is forced to see the difference between how England is and how it ought to be. Gulliver soon understands that he must have been very revolting to the Lilliputians.
In the third voyage, Gulliver travels to Laputa (and neighbouring Luggnagg and Glubdugdribb). When he visits the island of Glubdugdribb, he gets the power to call up the dead and discovers the deceptions of history. In the land of Laputa, the people are over-thinkers and are outrageous in many ways. He also meets the Stuldbrugs there, which is basically a race that is blessed with immortality. But Gulliver finds out that they are miserable.
In the fourth voyage, Gulliver travels to the land of Houyhnhnms, who are horses gifted with a reason. Their coherent, clean, and trouble-free society is contrasted with the foulness and brutality of the Yahoos, who are beasts in human shape. Gulliver manages to unwillingly come to recognize their human vices. He ends up staying with the Houyhnhnms for many years and gets totally captivated with them to a point that he never wants to leave. When he gets to know that the time has come for him to leave the island, he faints from unhappiness. When he returns to England, Gulliver feels appalled about other humans, including his own family.
