•Why it earns a slot
Black Beauty is the book most credited with shifting British and American public opinion against bearing-reins and other fashionable horse abuses in the 1880s and 1890s, making it one of the most consequential animal-welfare documents ever written in the form of fiction.
Told in the first person by a horse, Black Beauty traces his life from a happy foalhood on an English farm through a long series of owners ranging from kind to brutal. The novel follows his steady decline through overwork, injury, and neglect before a final rescue restores him to comfort and security. Along the way Sewell uses Beauty's observations to argue passionately against check-reins, bearing-reins, drunken drivers, and every form of animal cruelty.
