The Scarecrow of Oz is the ninth book set in the Land of Oz written by L. Frank Baum. Scarecrow is a character in the fictional Land of Oz. In his first appearance, the Scarecrow reveals that he lacks a brain and desires above all else to have one. In reality, he is only two days old and merely ignorant. Throughout the course of the novel, he demonstrates that he already has the brains he seeks and is later recognized as "the wisest man in all of Oz," although he continues to credit the Wizard for them. He is, however, wise enough to know his own limitations and all too happy to hand the rulership of Oz, passed to him by the Wizard, to Princess Ozma, to become one of her trusted advisors, though he typically spends more time playing games than advising.
