Etymology The Israeli cabinet ratified the name "Israel Defense Forces" (), Tzva HaHagana LeYisra'el, literally "army for the defense of Israel," on 26 May 1948. The other main contender was Tzva Yisra'el (). The name was chosen because it conveyed the idea that the army's role was defense, and because it incorporated the name Haganah, the pre-state defensive organization upon which the new army was based. Among the primary opponents of the name were Minister Haim-Moshe Shapira and the Hatzohar party, both in favor of Tzva Yisra'el. History The IDF traces its roots to Jewish paramilitary organizations in the New Yishuv, starting with the Second Aliyah (1904 to 1914). The first such organization was Bar-Giora, founded in September 1907. Bar-Giora was transformed into Hashomer in April 1909, which operated until the British Mandate of Palestine came into being in 1920. Hashomer was an elitist organization with narrow scope, and was mainly created to protect against criminal gangs seeking to steal property. The Zion Mule Corps and the Jewish Legion, both part of the British Army of World War I, would further bolster the Yishuv with military experience and manpower, forming the basis for later paramilitary forces. After the 1920 Palestine riots against Jews in April 1920, the Yishuv leadership realized the need for a nationwide underground defense organization, and the Haganah was founded in June of the same year. The Haganah became a full-scale defense force after the 1936–1939 Arab revolt in Palestine with an organized structure, consisting of three main units—the Field Corps, Guard Corps, and the Palmach. During World War II, the Yishuv participated in the British war effort, culminating in the formation of the Jewish Brigade. These would eventually form the backbone of the Israel Defense Forces, and provide it with its initial manpower and doctrine. Following Israel's Declaration of Independence, Prime Minister and Defense Minister David Ben-Gurion issued an order for the formation of the Israel Defense Forces on 26 May 1948. Although Ben-Gurion had no legal authority to issue such an order, the order was made legal by the cabinet on 31 May. The same order called for the disbandment of all other Jewish armed forces. The two other Jewish underground organizations, Irgun and Lehi, agreed to join the IDF if they would be able to form independent units and agreed
