Mandaeism
There are thought to be between 60,000 and 70,000 Mandaeans worldwide, and until the 2003 Iraq war, almost all of them lived in Iraq. The 2003 Iraq War reduced the population of Iraqi Mandaeans to approximately 5,000 by 2007.  Most Iraqi Mandaeans fled to Syria and Jordan under the threat of violence by Islamic extremists and the turmoil of the war.
