The IDF was established on May 31, 1948, two weeks after the establishment of the State of Israel. The acronym IDF stands for Israel Defense Forces, and the Hebrew letters stand for Tzva Haganah Le'Yisrael, or, quite literally, Israel Defense Army (צה"ל). It was comprised of several underground organizations and brigades fighting for the independence before 1948, also all acronyms: Palmach (פלמ"ח), Lechi (לח"י) and Etzel (אצ"ל).
