Gulliver's Travels was written by Jonathan Swift and first published in 1726. One of the top classic books, the original book presents itself as a simple traveller's narrative with the title Travels into Several Remote Nations of the World, in Four Parts, its authorship attributed to "Lemuel Gulliver, first a surgeon, then a captain of several ships." Different editions contain different versions of the prefatory material. The main body of the book is divided into four parts: (i) A Voyage to Lilliput (May 4, 1699 - April 13, 1702); (ii) A Voyage to Brobdingnag (June 20, 1702 - June 3, 1706); (iii) A Voyage to Laputa, Balnibarbi, Luggnagg, Glubbdubdrib, and Japan (August 5, 1706 - April 16, 1710); and (iv) A Voyage to the Country of the Houyhnhnms (September 7, 1710 - July 2, 1715). Despite the complexity of the work, Gulliver's Travels is often classified as a children's story because of the popularity of the Lilliput section. Broad overall themes include a satirical view of the state of European government as well as an analysis of whether men are inherently corrupt or whether they become corrupted. The book was an instant success and has become a classic in English literature.
