Black Beauty is a novel by English author Anna Sewell. It was composed in the last years of her life, during which she remained in her house as an invalid. The novel became an immediate bestseller, with Sewell dying just five months after its publication, long enough to see her first and only novel become a success. With fifty million copies sold, Black Beauty is one of the best-selling books of all time. While forthrightly teaching animal welfare, it also teaches how to treat people with kindness, sympathy and respect. Black Beauty became a forerunner to the pony book genre of children's literature.
