|Goblin Liberation Front|
The Goblin Liberation Front was a clandestine extremist group that advocated goblin rights, that was very active in the 1870s. Due to its eminence at the time, it also attracted a number of disaffected anarchist wizards.
After the mysterious incident that comprised the Quidditch World Cup in 1877 (after which no one could remember a single game, even though there was clear and ample evidence that a venue had been chosen, publicity materials had been produced, and tickets had been sold), theories about what had transpired included a mass Memory Charm perpetuated by the Goblin Liberation Front.
