Islamic State
The Islamic State (IS), also known as the Islamic State of Iraq and the Levant, Islamic State of Iraq and Syria, and by its Arabic acronym Daesh, is a militant Islamist group and former unrecognized quasi-state that follows the Salafi jihadist branch of Sunni Islam. It was founded by Abu Musab al-Zarqawi in 1999 and gained global prominence in 2014, when it drove Iraqi security forces out of key cities during the Anbar campaign, which was followed by its capture of Mosul and the Sinjar massacre.
