The history of the Islamic State of Iraq and the Levant (ISIL) began with the group's foundation in 1999 by Jordanian Salafi jihadist Abu Musab al-Zarqawi under the name Jamāʻat al-Tawḥīd wa-al-Jihād (transl. "The Organisation of Monotheism and Jihad"). In a letter published by the US State Department in February 2004, Zarqawi wrote that jihadists should use bombings to start an open sectarian war in Iraq so that Sunnis from other countries would mobilize against the assassinations carried out by Shias, specifically the Badr Organisation, against Ba'athists and Sunnis. The Islamic State would eventually grow to control territory with a population of millions.
