Reception of Refugees 1948-1949: Palestinian Refugees fleeing Israel ended up in Jordan, Lebanon , Syria, and Egypt . In Jordan, certain Palestinians were allowed to apply for citizenship, but the majority were not and they were forced to live in Refugee Camps. Those who did not become Jordanian citizens remain refugees and their children remain refugees to this day. Those who did become citizens have an identifier in their passports saying that they are Palestinian (which opens them up to discrimination).
Black September Sept. 1970 to July 1971: A Civil War in Jordan in which around 15,000 Palestinians (militants and civilians) were killed by Jordanian Authorities after the Palestinian pseudo-state that had developed in western Jordan had attempted to assassinate King Hussein. The Palestinians lost and the militants were forcibly evicted.
