The Fabian Society (/ˈfeɪbiən/) is a British socialist organisation whose purpose is to advance the principles of social democracy and democratic socialism via gradualist and reformist effort in democracies, rather than by revolutionary overthrow. It was historically related to some of the furthest left factions of radicalism, a left-wing liberal tradition.
As one of the founding organisations of the Labour Representation Committee in 1900, and as an important influence upon the Labour Party which grew from it, the Fabian Society has strongly influenced British politics. Members of the Fabian Society have included political leaders from other countries, such as Jawaharlal Nehru and Lee Kuan Yew, who adopted Fabian principles as part of their own political ideologies. The Fabian Society founded the London School of Economics in 1895.
