The Six-Day War, or the 1967 Arab–Israeli war (5–10 June 1967), was fought between Israel and a coalition of Arab states, primarily Egypt, Syria, and Jordan within the context of the Arab–Israeli conflict. In the war, Israel captured and occupied the West Bank (including East Jerusalem) from Jordan, the Gaza Strip and the Sinai Peninsula from Egypt, and the Golan Heights from Syria.
Military hostilities broke out amid poor relations between Israel and its Arab neighbors, who had been observing the 1949 Armistice Agreements signed at the end of the First Arab–Israeli War. In 1956, regional tensions over the Straits of Tiran (giving access to Eilat, a port on the southeast tip of Israel) escalated in what became known as the Suez Crisis, when Israel invaded Egypt over the Egyptian closure of maritime passageways to Israeli shipping, ultimately resulting in the re-opening of the Straits of Tiran to Israel as well as the deployment of the United Nations Emergency Force (UNEF) along the Egypt–Israel border.
