The Israeli annexation of East Jerusalem, known to Israelis as the reunification of Jerusalem, refers to the Israeli occupation of East Jerusalem during the 1967 Six-Day War, and its annexation. Jerusalem was envisaged as a separate, international city under the 1947 United Nations partition plan. It was, however, divided by the 1948 war that followed Israel's declaration of independence. As a result of the 1949 Armistice Agreements, the city's western half came under Israeli control, while its eastern half, containing the famed Old City, fell under Jordanian control. In 1950, Jordan annexed East Jerusalem as part of its larger annexation of the West Bank. Israel occupied East Jerusalem during the 1967 Six-Day War; since then, the entire city has been under Israeli control. In Israel, the reunification of Jerusalem is celebrated is commemorated as Jerusalem Day, an annual holiday. In July 1980, the Knesset passed the Jerusalem Law as part of the country's Basic Law, which declared unified Jerusalem the capital of Israel, formalizing its effective annexation. The United Nations Security Council ruled the law "null and void" in United Nations Security Council Resolution 478. Background Jordan and an alliance of Arab states rejected the 1947 UN Partition Plan under which Jerusalem was to be a corpus separatum, instead invading former Palestinian Mandate territory, and by the armistice in 1949 was in control of the Old City and East Jerusalem (excluding Mount Scopus). The Arab invading armies failed to take control over the rest of Israel, including West Jerusalem. The city was then divided along the 1949 Armistice Line. East Jerusalem was annexed to Jordan in 1950. The city remained divided until the Six-Day War in 1967. As part of the Jordanian campaign, on June 5, 1967, the Jordanian Army began shelling Israel. When the Israeli cabinet convened to decide how to respond, Yigal Allon and Menahem Begin argued that this was an opportunity to take the Old City of Jerusalem, but Eshkol decided to defer any decision until Moshe Dayan and Yitzhak Rabin could be consulted. During the late afternoon of June 5, the Israelis launched an offensive to encircle Jerusalem, which lasted into the following day. On June 7, heavy fighting ensued. Dayan had ordered his troops not to enter the Old City; however, upon hearing that the UN was about to declare a ceasefire, he changed his mind, and without cabinet clearance, decided to capture it.
