Glinda or Glinda the Good Witch is a fictional character in the Land of Oz created by American author L. Frank Baum. She is the most powerful sorceress of Oz, ruler of the Quadling Country south of the Emerald City, and protector of Princess Ozma.
Baum's beloved 1900 novel The Wonderful Wizard of Oz refers to Glinda as the Good Witch of the South. Later books call her a "sorceress" rather than a "witch". Baum's writings make clear that he did not view witches as inherently wicked or in league with the Devil, so this change was probably meant to signal that Glinda was even more powerful than a witch.
Glinda is usually described as the most powerful magician in Oz. In The Patchwork Girl of Oz, neither Ozma nor the Wizard can break a spell, but later it is revealed that Glinda can do so. In the books, Glinda is depicted as a tall young woman with red hair in a clinging white dress.
Besides a vast knowledge of magic, Glinda employs various tools, charms, and instruments in her workshop. The Emerald City of Oz reveals that she owns a Great Book of Records that allows her to track everything that goes on in the world from the instant it happens.
Glinda lives in a palace near the southern border of the Quadling Country, attended by one hundred beautiful maidens (twenty-five from each country of Oz). She also employs a large army of female soldiers, with which she placed Ozma on the throne of Oz at the end of The Marvelous Land of Oz. Men are not much in evidence in Glinda's society.
As a ruler, Glinda is strongly protective of her subjects. She creates gated communities for the rabbits of Bunnybury and the paper dolls of Miss Cuttenclip, and later in The Emerald City of Oz seals off all of Oz from the Great Outside World for its security. However, unlike Ozma, Glinda is willing to ignore strife and oppression in remote corners of Oz like Jinxland and the Skeezer territory as long as it does not threaten the Emerald City or innocent outsiders.
