The Deerslayer, or The First Warpath (1841) was the last of James Fenimore Cooper's Leatherstocking tales to be written. Its 1740-1745 time period makes it the first installment chronologically and in the lifetime of the hero of the Leatherstocking tales, Natty Bumppo. The novel's setting on Otsego Lake in central, upstate New York, is the same as that of The Pioneers, the first of the Leatherstocking tales to be published (1823). The Deerslayer is considered to be the prequel to the rest of the Leatherstocking tales. Fenimore Cooper begins his work by relating the astonishing advance of civilization in New York State, which is the setting of four of his five Leatherstocking tales.

James Fenimore Cooper (September 15, 1789 - September 14, 1851) was an American writer. He created the character of Natty Bumpo, the archetypal American frontiersman.
