Like a memoir, an autobiography is the author’s retelling of his or her life and told in first person point of view, making the author the main character of the story.
Autobiographies are also narrative nonfiction, so the stories are true but also include storytelling elements such as a protagonist (the author), a central conflict, and a cast of intriguing characters.
