As members of an underground armed organization, Irgun personnel did not normally call Irgun by its name but rather used other names. In the first years of its existence it was known primarily as "Ha-Haganah Leumit"' (The National Defense), and also by names such as "Haganah Bet" ("Second Defense"), "Irgun Bet" ("Second Irgun"), the "Parallel Organization" and the "Rightwing Organization". Later on it became most widely known as המעמד (the Stand). The anthem adopted by the Irgun was "Anonymous Soldiers", written by Avraham (Yair) Stern who was at the time a commander in the Irgun. Later on Stern defected from the Irgun and founded Lehi, and the song became the anthem of the Lehi. The Irgun's new anthem then became the third verse of the "Betar Song", by Ze'ev Jabotinsky.
