The IDFtraces 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. It was converted to Hashomer in April 1909, which operated until the British Mandate of Palestinecame 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. During World War I the forerunners of the Haganah/IDF were the Zion Mule Corps and the Jewish Legion. After the Arab riotsagainst Jews in April 1920, the Yishuv's leadership saw the need to create 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 successor to the Jewish Legion of World War I was the Jewish Brigade.
The IDF was founded following the establishment of the State of Israel, after Defense Minister and Prime Minister David Ben-Gurionissued an order on May 26, 1948. The order called for the establishment of the Israel Defense Forces, and the abolishment of all other Jewish armed forces. Although Ben-Gurion had no legal authority to issue such an order, the order was made legal by the cabineton May 31
