The purpose of the biography:

There are two types of ways to write about someone's life. You can write about someone's life or they can write about their own life. When the person writes about their own life it is called an autobiography. When you write about their life it's called a biography. Each form can be fiction or nonfiction. The purpose of the biography is to take a person's highlighted events that occur in fiction or nonfiction form and explain them in a story. Most celebrities and well accomplished people use biographies to give the public a roadmap to their success. People who have survived horrific events also use biographies to tell their story. Some biographies don't even have to be about humans they can be based off of animals as well.
