"B.O.G. cannot condone the use of violence to further its aims"
-- a cheerful Brodrig the Boss-Eyed, interviewed by the Daily Prophet (DP3)
A group pressing for goblin rights, including the right to carry and use wands
Members of the B.O.G. were meeting with Ministry representatives in Chipping Clodbury when a small riot broke out. Some goblins got hold of real wands and were transfiguring post boxes and litter bins into wildebeests and marching through the streets chanting B.O.G. slogans and calling for the release of Hodrod the Horny-Handed. The leader of the organisation is Brodrig the Boss-Eyed (DP3)
There exist several labour movements/groups, calling themselves the "Brotherhood of xxx", and who aim to collectively obtain better conditions and rights for their members
Chipping Clodbury is almost certainly derived from the name of a town in which Rowling grew up, Chipping Sodbury.
While the date printed on DP3 is 1 June 1999, the timeframe for these events is 1992-1993.
