What is a character sketch for the King of Lilliput?

The Lilliputian Emperor is presented by Swift as an absurd, laughable character. He is an autocrat who takes himself very seriously indeed—a little too seriously, perhaps. As well as being rather pompous, the Emperor is quite small-minded and vindictive, executing his subjects for the most trifling of infractions. For all the finery of his court and the lavishness of his hospitality, the Emperor is nothing more than a petty tyrant who wants to conquer and enslave the Blefuscans for no good reason.
Although the Emperor likes to think that he's the one in charge, in actual fact he's easily manipulated by his ministers and other court lackeys. He insists on absolute loyalty to himself and his often ridiculous policies on pain of death. Gulliver discovers this for himself when he refuses to go along with the Emperor's plan to destroy Blefuscu. The Emperor is deeply offended by Gulliver's refusal and, egged-on by his toady advisers, sets out to have him executed for high treason.
