In June 1992, indigenous peoples, environmentalists, activists, and heads of state gathered in Rio de Janeiro, Brazil for the Earth Summit and the Global Forum. The Earth Summit, officially called the United Nations Conference on Environment and Development (UNCED), brought together 118 heads of state, making it the largest summit meeting ever held. It was, "as promised, the most significant UN gathering since its inception in 1945," according to the U.S. Citizens Network Newsletter.
