Why did Gulliver cross the Chanel and go to the blefuscu?

Gulliver crossed the Channel to Blefuscu primarily to escape the political turmoil and oppression in Lilliput, where he had fallen out of favor with the emperor. He sought refuge in Blefuscu, a rival nation, where he hoped to find a more hospitable environment. Additionally, his journey reflects themes of exploration and the pursuit of freedom from authoritarian rule.
