There are close to 30 million Kurds spread across northern Syria, northern Iraq, southern Turkey, and western Iran.  They are the largest ethnic group without a homeland in the world.  In the 1990s, the Kurds in northern Iraq, with the aid of the Coalition no-fly zone, began to develop their own autonomy, in what is now known as Iraqi Kurdistan.  The Kurdistan Regional Government is functionally now its own country, although it is still officially recognized as part of Iraq.
