Hunted to extinction in Britain during the 18th century, the wolf was until relatively recently a native inhabitant of the British Isles. In packs, they were known to be deadly predators to both other animals and humans alike. According to writings from ancient British chroniclers, they used to be extremely numerous across the Isles. Many Medieval British kings and officials offered a bounty to hunters for wolf pelts and heads in an attempt to cull the population. While they no longer exist in Britain today outside of zoos, the species continues to thrive across the rest of the world.
