S.E. Hinton was inspired to write The Outsiders based on her experiences in high school in the 1950s in Tulsa, Oklahoma. She observed social divisions between lower class "Greasers" and wealthy "Socs." The 1967 novel is about class conflict between the Greaser gang and the Socs. It explores themes of violence, prejudice and finding one's place in the world. The story is told in first person by the protagonist Ponyboy Curtis and examines what it means to be an outsider from both sides of the social divide.
