Animal Liberation Leagues were a network of animal rights organizations active in the UK in the 1980s. Whereas the Animal Liberation Front specialized in clandestine activity, mainly masked, at night, and involving small numbers of people, the Animal Liberation Leagues consisted of coordinated raids, or 'invasions', by a large number of people, mainly carried out during the day. One journalist described the Animal Liberation Leagues as "a sophisticated...development in the move to direct action". Raids were often carried out at the same time as legal demonstrations.
