Terrorism, in some of its definitions, serves to communicate a message from terrorists to a target audience (TA). By extension, symbols play an important role in such communication, through graphics that the organizations use to represent themselves, as well as the meaning and significance behind their choice of targets. Symbolism of terrorist groups Terrorist organizations use graphic marks and insignias as symbols to represent their ideology, purpose, and goals. These insignias are replete with meaningful symbols that communicate the message, purpose, history, and goals of the organizations. As such, they contribute to the creation of unique organizational culture. A few databases exist which catalog the symbols used in terrorist images and propaganda, the most prominent of which are the International Terrorist Symbols Database and the Islamic Imagery Project. Also exist the academic research "Terroristica". International Terrorist Symbols Database The International Terrorist Symbols Database is a compilation of insignias from terrorist organizations put together by the Anti-Defamation League. Published on their website, it features profiles of thirty different symbols from groups such as Al Qaeda in Iraq, Hamas, Hezbollah, the Muslim Brotherhood, the Popular Front for the Liberation of Palestine, and others. Not all of the groups discussed are officially recognized on the U.S. State Department's Foreign Terrorist Organizations list, yet they all have references to attacks made by the organization. Each image profile contains a description of the insignia, an explanation of the symbols involved, and a detailed history of the organization's history, ideology, goals, leaders, and major attacks. Below are examples of a few of the terrorist images included in the database, along with the corresponding analysis of the symbols involved in the image. Al Qaeda in Iraq One of several emblems used by Al Qaeda in Iraq, the adjacent image depicts a gray globe positioned in a black background. On top of the globe is an open Quran, from which a rifle, a fist, and a flag emerge. The yellow writing beneath the globe may be translated as "Monotheism and Jihad." The flag represents Al Qaeda in Iraq's goal of creating an Islamic caliphate,while its color denotes the death and the militant means the organization is willing to take to achieve this goal. The rifle and fist are also symbols of militancy. By positioning these symbols on top of the Quran, the image communicates the foundation of their mission in Islam, while the globe indicates their worldwide ambitions
