The origins of the Islamic State group can be traced back to three main organizations. Earliest of these was the "Jamāʻat al-Tawḥīd wa-al-Jihād" organization, founded by the Jihadist leader Abu Mus'ab al-Zarqawi in Jordan in 1999. Although the other two predecessor organizations emerged during the Iraqi insurgency against the U.S. occupation forces which included the "Jaish al-Ta'ifa al-Mansurah" group founded by Abu Omar al-Baghdadi in 2004 and the "Jaysh Ahl al-Sunnah wa’l-Jama’ah" group founded by Abu Bakr al-Baghdadi and his associates in the same year, the modern iteration of the Islamic State was formed after the U.S. occupational forces outlawed the Iraqi branch of the Arab Socialist Ba'ath Party putting the Sunni soldiers and bureaucrats out of work.
