In June 1967, during the Six Day war, Israel captured the heights. Six years later, in a surprise attack during what became known as the Yom Kippur war, Syria overran the Golan before being repulsed by Israeli counterattacks. After the war, Syria signed a disengagement agreement that left the Golan in Israel's hands. On 14 December 1981, the Knesset voted to annex the Golan Heights.
