Satire runs throughout all four worlds in Gulliver's travels.
"Satire is a sort of glass wherein beholders do generally discover everybody's face but their own; which is the chief reason that so very few are offended with it." .
Frequently at this time literature was used as a political tool, it was used to send messages, make people think, and to make insubordinate criticism to monarchy, political parties or religious factions. To do this effectively, Swift used Satire. This is where writing exposes the follies of human behavior by presenting it as absurd or ridiculous. It is not what is said that what is important but what is inferred. The story of Gulliver's travels was effectively split into 4 parts (or the four different worlds) Each world Satirizes a different factor or part on England.
In his first voyage to Lilliput, Gulliver is shipwrecked. His captors are a twelve of his own size but they manage to secure him as their prisoner. The social and political background of these people is similar to that of the people in England. Satire is introduced gradually in Lilliput- sometimes at Gulliver's expense, but more often at the expense of the Lilliputians. "Slender ligatures" tie Gulliver and while he is being fed he considers himself "bound by the laws of hospitality," The Emperor is intended to represent King George I, who reigned in Swift's time, and there are also many resemblances to King George in the description of the King of Laputa whom we meet later.
An example of satire in Lilliput is the war Gulliver won for the Lilliputians. It started by petty disagreements. In this case it's the side the egg is cracked open. The native Blefescu or France, are breaking their eggs the opposite side. This leads to war. Between these years Britain was at war with France. So this is an indirect comparison. People which didn't comply in the story were exiled and for what? For not breaking their egg at the right end.
