East Jerusalem or Eastern Jerusalem (Arabic: القدس الشرقية, Hebrew: מזרח ירושלים) is the sector of Jerusalem that was not part of Israeli-held West Jerusalem at the end of the 1948–1949 Arab–Israeli War. Israeli and Palestinian definitions of it differ; the Palestinian official position is based on the 1949 Armistice Agreements, while the Israeli position is mainly based on the current municipality boundaries of Jerusalem, which resulted from a series of administrative enlargements decided by Israeli municipal authorities since the June 1967 Six-Day War. Despite its name, East Jerusalem includes neighborhoods to the north, east and south of the Old City, and in the wider definition of the term even on all these sides of West Jerusalem.
During the 1948 Arab–Israeli War, Jerusalem was contested between Jordan and Israel, and on the cessation of hostilities, the two countries secretly negotiated a division of the city, with the eastern sector coming under Jordanian rule. This arrangement was formalized in the Rhodes Agreement in March 1949. A week after David Ben-Gurion presented his party's assertion that "Jewish Jerusalem is an organic, inseparable part of the State of Israel" in December 1949, Jordan annexed East Jerusalem. These decisions were confirmed respectively in the Knesset in January 1950 and the Jordanian Parliament in April 1950.
On being captured by Israel in the 1967 Six-Day War, East Jerusalem, with expanded borders, came under Israeli rule. It includes Jerusalem's Old City and some of the holiest sites of Judaism, Christianity, and Islam, such as the Temple Mount, Western Wall, Al-Aqsa Mosque, Dome of the Rock and the Church of the Holy Sepulchre.
