The PLO subsequently committed itself to peace negotiations with Israel brokered by the international community. These began with the Madrid Conference in 1991, and resulted in the signing of the Oslo Accords in 1993, leading to the creation of the Palestinian National Authority. In 2002, a Quartet of third-party brokers developed a road map for peace aimed at achieving a viable solution to the conflict including the establishment of a Palestinian state. The current outline for a solution was determined and agreed to by both parties during the Annapolis Conference of 2007.
