ISIS, ISIL, Islamic State? A terminology primer

Fred Dews

“ISIL is not ‘Islamic’ … and ISIL is certainly not a state,” said President Obama in a September 2014 speech about the terrorist organization commonly referred to as Islamic State. The self-proclaimed caliphate has been called many names. Here is a primer on the terminology, drawn from our latest Brookings Essay, “The Believer,” by Will McCants on the rise of Islamic State leader Abu Bakr al-Baghdadi.

Islamic State in Iraq

When it was established in 2006, the group called itself the Islamic State of Iraq. The group’s devotees often shortened the name to the Islamic State.

ISIS

In April 2013, Baghdadi officially renamed Islamic State of Iraq the “Islamic State in Iraq and al-Sham,” the Arabic term for the eastern Mediterranean region. Jihadists often use the term to refer to Syria alone.

ISIL

President Obama and the U.S. government use the acronym “ISIL,” which stand for “Islamic State in Iraq and the Levant.” The Levant, from a French word, covers most of al-Sham.

Daesh

Some Western officials use the Arabic acronym for ISIS, Daesh, because Islamic State members reportedly find the acronym offensive.
