Lemuel Gulliver, a learned surgeon, decides to go for sea voyages to the remote islands of the world, as he is keen to explore the world.

During his first voyage, Gulliver is shipwrecked because of a storm but manages to swim safely to Lilliput. While sleeping, Gulliver is held captive by about six inches tall inhabitants of the island. Due to his large size, Gulliver is initially perceived to be a threat. Later on, he is considered to be a harmless creature but a great expense on the kingdom. After getting a brief summary of their historical events, Gulliver decides to assist them in their battle against their rival state, Blefuscu. He stops the battle by bringing the enemy fleets to the kingdom. For this, he is honoured with the title of a Nardac by the king. Flimnap and Skyresh Bolgolam, officials of the court, envy his success and conspire against him. They bring out four articles of impeachment against him. These are extinguishing the fire at the queens palace in a disgraceful manner, refusing to obey the kings order to enslave the Blefuscudians, maintaining good behaviour with the delegates of the enemy and planning a visit to Blefuscu, their enemy. Therefore, an order is passed to blind him before starving him to death. Fortunately, Gulliver is warned against the charges beforehand and he escapes to Blefuscu. The emperor of Blefuscu welcomes him warmly. In Blefuscu, he finds a broken boat, which he repairs, and sails back to England.

Within two months of his return, Gulliver departs for another voyage. During the voyage, their ship gets drifted by a storm. Some of the crew members get down at the shore of a deserted island to find drinking water. Unfortunately, Gulliver is left alone on this island of giants. In Brobdingnag, he is taken to a farmer home and is left in the care of his nine years old daughter, Glumdalclitch. The farmer earns a good fortune by making him perform at various places. Consequently, Gullivers health starts deteriorating and the farmer sells him to the queen. Though the king and the queen treat him with respect and fondness, Gulliver faces several misfortunes threatening his life. One day, his box apartment, in which he was carried by Glumdalclitch, is picked by an eagle and dropped into the sea. Finally, he is rescued by an English ship.

Again, his thirst of seeing the world takes Gulliver on a new voyage. In this voyage, his sloop is attacked by the pirates. Gulliver is punished by being left in the sea in a small boat with scanty provisions. He reaches a group of islands. On fifth day, he reaches an island where he finds a land mass floating in the air. He is pulled up to the island by chains. He finds the inhabitants busy in their own thoughts and interested in only mathematics and music. Hence, he decides to visit Balnibarbi, where he is hospitably received by Lord Munodi. Gulliver observes that Lord Munodis estate is greener and more systematically built than the other part of the country as it follows the ancient methods of agriculture and construction.Further, he visits the academy of projectors in Lagado where the scientists are busy in their researches and the teachers are involved in speculative learning. Then, he visits Glubdubbdrib where he gets a chance to communicate with the worlds great philosophers and tyrants who died several years ago. Finally, he travels to Luggnagg. The king makes arrangements for his departure to Japan from where he boards a ship back to England.

In his final voyage, Gulliver takes up the post of the captain of the ship. As most of his crewmen die because of sea sickness, he hires men from various islands who turn out to be rogues. Consequently, they leave Gulliver on a marooned island. On this island, Gulliver finds a race horses, called Houyhnhnms, governing the island with intelligence. They are being served by a race of wild human-like creatures called Yahoos. Gulliver realises that the Houyhnhnms are the most virtuous race on theearth, whereas the humans were full of vices. Therefore, he decides to live in the company of the Houyhnhnms forever. But, Gulliver is forced to leave the Houyhnhnmland. He decides to shun human company and live the rest of his life on a secluded island. But, the crew of a Portuguese ship, in command of Pedro de Mendez, discovers him and takes him to Lisbon. Gulliver rejects humans as he feels disgusted by their vices and the offensive odour of their bodies. Yet, the captain treats him hospitably and makes arrangements for his return to England. Gulliver reaches back home safely but maintains distance from his family members and spends most of the time in a stable with a pair of horses whom he treats as companions and converses well with. Only after about five years, he start coming to terms with the mankind.
