Divide and Rule is a 1948 collection of two science fiction novellas by American writer L. Sprague de Camp, first published in hardcover by Fantasy Press, and later reissued in paperback by Lancer Books in 1964.

He appreciates the basis of de Camp's science fiction "in the behaviour of real people living in unfamiliar social set-ups, logically developed from to-day's trends or from a given premise."

He considers "The Stolen Dormouse... more solidly based," but nonetheless singles out for praise "the description of the hero's wedding night, spent under his wife's bed in the company of a tame puma and in the throes of hay fever.

"[8] Astounding reviewer P. Schuyler Miller praised the book for "provid[ing] more sheer entertainment than any the fantasy publishers have yet given us," noting that de Camp uses his "detailed knowledge of history" to depict "hypothetical future societies which ape those of the past--with differences.

Calling de Camp "the funniest writer in science fiction," he noted that "[t]hough the writing was choppy in spots, the details of an utterly unique social set-up, complete with its own slang, was engrossingly worked out and chuckle-provoking.
