The author has created satire on british kingdom.If yes, why?

Each of the four voyages in Gulliver's Travels serves as a vehicle for Swift to expose and excoriate some aspect of human folly. The first voyage has been interpreted as an allegorical satire of the political events of the early eighteenth century, a commentary on the moral state of England, a general satire on the pettiness of human desires for wealth and power, and a depiction of the effects of unwarranted pride and self-promotion. The war with the tiny neighboring island of Blefuscu represents England's rivalry with France. In Brobdingnag, Gulliver's diminutive status serves as a reminder of how perspective and viewpoint alter one's condition and claims to power in society. The imperfect, yet highly moral Brobdingnagians represent, according to many critics, Swift's conception of ethical rulers. The voyage to Laputa, the flying island, is a scathing attack upon science in the sixteenth and seventeenth centuries and reveals Swift's thorough acquaintance with the Philosophical Transactions of the Royal Society, the leading publication of the scientific community of his day. The third voyage unequivocally manifests Swift's contempt and disdain for abstract theory and ideology that is not of practical service to humans. But it is the voyage to the land of the Houyhnhnms that reveals Swift's ultimate satiric object—man's inability to come to terms with his true nature. In particular, the Houyhnhnms are interpreted as symbols and examples of a human order that, although unattainable, deserves to remain an ideal, while the Yahoos are found to be the representatives of the depths of humanity's potential fall if that ideal is abandoned.
