The Palestine Liberation Organization (PLO) was founded by Ahmed Shukeiri in 1964, with the aim of representing the Palestinian people and their nationalist aspirations. The organization was created in response to the Arab defeat in the 1967 Six-Day War with Israel and was originally composed of various Palestinian factions, including political parties, resistance groups, and refugee committees. The PLO is recognized as the sole legitimate representative of the Palestinian people by the Arab League and the United Nations. Over the years, the PLO has undergone various transformations and internal conflicts, and has engaged in both armed struggle and diplomacy in its quest for Palestinian self-determination.
