The Mastiff's history is deeply rooted in antiquity, with ancestors believed to have existed over 2,500 years ago in the mountains of Asia. These ancient molossers were used as war dogs and guardians. Mastiffs were brought to Britain by Phoenician traders, where they were further developed. The Romans, impressed by their size and ferocity, used them in arena combat against gladiators, lions, and other animals. During the medieval period, they guarded estates and served as hunting dogs. The breed nearly went extinct after World War II, but dedicated breeders in North America and Britain helped restore their numbers. The American Kennel Club (AKC) officially recognized the Mastiff in 1885.
