are the basic organisation which anarchists
create to spread anarchism
. The term "affinity group
" comes from the Spanish F.A.I
. (Iberian Anarchist Federation) and refers to the organisational form devised by the Spanish Anarchists in their struggles. It is the English translation of "grupo de afinidad."
At its most basic, it is a (usually small) group of anarchists who work together to spread their ideas to the wider public, using propaganda, initiating or working with campaigns and spreading their ideas within popular organisations (such as unions) and communities. It aims not to be a "leadership" but to give a lead, to act as a catalyst within popular movements.
