Battle of Karameh
The 1967 Six-Day War exerted a significant effect upon Palestinian nationalism, as Israel gained military control of the West Bank from Jordan and the Gaza Strip from Egypt. Consequently, the PLO was unable to establish any control on the ground and established its headquarters in Jordan, home to hundreds of thousands of Palestinians, and supported the Jordanian army during the War of Attrition, which included the Battle of Karameh. However, the Palestinian base in Jordan collapsed with the Jordanian–Palestinian civil war in 1970. The PLO defeat by the Jordanians caused most of the Palestinian militants to relocate to South Lebanon, where they soon took over large areas, creating the so-called "Fatahland".
