"I was going to put Stop the Outrageous Abuse of Our Fellow Magical Creatures and Campaign for a Change in Their Legal Status - but it wouldn't fit. So that's the heading of our manifesto."
-- Hermione Granger (GF14)
Founded in 1994 by Hermione Granger in response to what she saw as gross injustice in the treatment of house-elves. The Society didn’t exactly catch on among Hogwarts students, but she persevered. Eventually (fall of 1995) she started knitting hats and socks which she left lying around Gryffindor tower, hoping to free some unsuspecting elf who picked them up while cleaning the common room. Once the elves discovered the hidden garments, they were deeply offended and refused to clean Gryffindor Tower anymore. Dobby picked up the slack, doing all the cleaning himself.
