The Fabian Society is a British socialist organization whose purpose is to advance the principles of democratic socialism through gradualist and reformist effort in democracies, rather than by revolutionary overthrow. The Fabian Society founded the London School of Economics and Political Science in 1895. Today, the society functions primarily as a think tank and is one of 21 socialist societies affiliated with the Labour Party.

The Fabian Window, designed in 1910 by George Bernard Shaw, shows a coat of arms bearing a wolf in sheep’s clothing. In the window, two Fabians, Sidney Webb and Edward R. Pease, are helping build ‘the new world’ while other Fabians kneel worshipfully before a stack of Fabian writings.
