The Basic Income Earth Network (BIEN; until 2004 Basic Income European Network) is a network of academics and activists interested in the idea of a universal basic income, i.e. a guaranteed minimum income based solely on citizenship and not on work requirement or charity. It serves as a link between individuals and groups committed to or interested in basic income, and fosters informed discussion on this topic throughout the world. Their website defines a basic income as "an income unconditionally granted to all on an individual basis, without means test or work requirement."
Formed in 1986, BIEN held its first international conference in Louvain-la-Neuve in September of that year. It expanded its scope from Europe to the Earth in 2004. From 1988 they published a paper newsletter three times per year; now replaced by an electronic newsletter distributed six times per year.
