Yvetot (7), an old town in the dep. of Seine-Inférieure, 24 m. NW. of Rouen, with manufactures of textile fabrics, and a trade in agricultural produce, the seigneurs of which long bore the title of king, "Roi d'Yvetot," a title satirically applied by Béranger to Napoleon, and often employed to denote an insignificant potentate with large pretensions.
