Palestinian refugees
In 1949, UNRWA formally defined the term "Palestine refugee" to refer to any Palestinian citizen or the descendant of any male Palestinian citizen who—if their regular place of residence was located within Mandatory Palestine between 1 June 1946 and 15 May 1948—was found to have "lost both home and means of livelihood" during the 1948 Palestine war. While this definition originally included Arab Palestinians displaced from or within Israel as well as Jewish Palestinians displaced from Arab-controlled territory, it ceased to apply to Arabs and Jews who became Israeli citizens in 1952; Arab Palestinians who were displaced from their homes while ultimately remaining within Israeli territory were instead designated as "present absentees" and not subject to UNRWA's jurisdiction.
