The kibbutz was established in 1944 by a small group of mainly Romanian immigrants. The first-generation settlers were members of the MarxistZionist youth movementHashomer Hatzair. Following the 1948 Arab–Israeli Warthe United Nations-established border between Israel and Syria was drawn to run only a few hundred yards east of the kibbutz. On Thursday 13 June 1974, four PF-GC terrorists infiltrated the Lebanon-Israel border and invaded the kibbutz. They entered one of the buildings shooting Edna Mor and Shoshana Galili. Edna left behind a child and husband who moved out of the kibbutz shortly after. The terrorists continued shooting at random. Judith Sinton, a volunteer from New Zealand, on her way back to the apiary after breakfast, was shot by a terrorist and killed. The members of the kibbutz seized their weapons and ran in the direction from where gunfire was heard. In the gun battle that followed, all four terrorists were killed. The terrorists' aim was to take Israeli hostages in return for 100 jailed terrorists. Their written message ends: "We love to die, as you love to live." The artistAvraham Eilat who was at that time a member of the kibbutz documented the event.
Economy
As of 2006, Shamir was one of the most prosperous kibbutzim in Israel, producing honey, toiletries, and advanced optical products. The optical enterprise, Shamir Optical Industry, is a fully incorporated stock company and is quoted on NASDAQ. The kibbutz also earns money from tourism; it offers views of Mount Hermon to the north and the Hula Valley below the kibbutz. A relatively rare phenomenon can be observed from Shamir – a "sunrise in the west." As the kibbutz is nested in the steeply-rising western slopes of the Golan, when the sun rises, its first rays at daybreak illuminate the peaks of the Ramim mountain range across the valley to the west of Shamir. As the sun climbs progressively higher, more of Ramim is bathed in sunshine, which can then be observed progressing from west to east, down the slopes of Ramim, across the valley and up the slopes of the Golan before reaching the kibbutz.
Landmarks
Of notable interest are some 3rd century border stones with Greek inscriptions. Surrounding the kibbutz is a field of more than 400 dolmens, dated to the Bronze Age IB . The largest of the dolmens has a basalt capstone of 50 tons which has rock art on its underside—the only art known from dolmens in the southern Levant. Its excavators judge that the scale of the dolmen field and size of the dolmens indicate a governmental system more complex than that usually assigned to the period.
