The Six-Day War (Hebrew: מלחמת ששת הימים, Milhemet Sheshet Ha Yamim; Arabic: النكسة, an-Naksah, "The Setback," or حرب 1967, Ḥarb 1967, "War of 1967"), also known as the June War, 1967 Arab-Israeli War, or Third Arab-Israeli War, was fought between June 5 and 10, 1967, by Israel and the neighboring states of Egypt (known at the time as the United Arab Republic), Jordan, and Syria.
The war began on June 5 with Israel launching surprise bombing raids against Egyptian air-fields after a period of high tension that included an Israeli raid into the Jordanian-controlled West Bank,[11][12] Israeli initiated aerial clashes over Syrian territory,[13] Syrian artillery attacks against Israeli settlements in the vicinity of the border followed by Israeli response against Syrian positions in the Golan Heights and encroachments of increasing intensity and frequency (initiated by Israel) into the demilitarized zones along the Syrian border[14] and culminating in the Egyptian imposition of a naval blockade on Eilat and ordering of the evacuation from the Sinai Peninsula of the U.N. buffer force.
Within six days, Israel had won a decisive land war. Israeli forces had taken control of the Gaza Strip and the Sinai Peninsula from Egypt, the West Bank and East Jerusalem from Jordan, and the Golan Heights from Syria.
