The Palestine Liberation Organisation or PLO was formed in 1964 by the Arab states as an organisation embracing the various Palestinian resistance organisations into one organisation with the aim of creating a secular democratic state over the whole of pre-Second World War Palestine. Under the leadership of Yasser Arafat the PLO modified its objective to the creation of an independent Palestinian state in any part of Palestine from which Israel would agree to withdraw. The PLO was recognised by the United Nations in 1974. After the end of the 20th century the influence of the PLO among Palestinians had waned, to be replaced by more militant groups such as Hamas (formed in 1987 to oppose the Israeli occupation of the Palestinian territories of West Bank, Gaza and Jerusalem) and Hezbollah.
