Refugees of Iraq are Iraqi nationals who have fled Iraq due to war or persecution. Throughout the past 30 years, there have been a growing number of refugees fleeing Iraq and settling throughout the world, peaking recently with the latest Iraq War. Precipitated by a series of conflicts including the Kurdish rebellions during the Iran–Iraq War (1980 to 1988), Iraq's Invasion of Kuwait (1990) and the Gulf War (1991), the subsequent sanctions against Iraq, and culminating in the violence during and after the American-led invasion and occupation of Iraq, millions have been forced by insecurity to flee their homes in Iraq. Like the majority of refugees worldwide, Iraqi refugees have established themselves in urban areas in other countries rather than in refugee camps.
