Ba'athist Arabization campaigns in northern Iraq in the context of "Khanaqin"

Arabization or Arabicization (Arabic: تعريب, romanized: taʻrīb) is a sociological process of cultural change in which a non-Arab society becomes Arab, meaning it either directly adopts, is forced to accept, or becomes strongly influenced by the Arabic language, culture, literature, art, music, and ethnic identity as well as other socio-cultural factors. It is a specific form of cultural assimilation that often includes a language shift or linguistic imperialism. The term applies not only to cultures, but also to individuals, as they acclimate to Arab culture and become "Arabized". Arabization took place after the Muslim conquest of the Middle East and North Africa, as well as during the more recent Arab nationalist policies toward non-Arabic speaking minorities in modern Arab states, such as Algeria, Iraq, Syria, Egypt, Bahrain, and Sudan.

After the rise of Islam in the Hejaz and subsequent Muslims conquests, Arab culture and language spread outside the Arabian Peninsula through trade and intermarriages between members of the non-Arab local population and the peninsular Arabs. The Arabic language began to serve as a lingua franca in these areas and various dialects were formed. This process was accelerated by the migration of various Arab tribes outside of Arabia, such as the Arab migrations to the Maghreb and the Levant.

The Kurdistan Region (KRI) is a semi-autonomous federal region of the Republic of Iraq. It comprises four Kurdish-majority governorates of Arab-majority Iraq: Erbil Governorate, Sulaymaniyah Governorate, Duhok Governorate, and Halabja Governorate. It is located in northern Iraq, which shares borders with Iran to the east, Turkey to the north, and Syria to the west.

It does not govern all of Iraqi Kurdistan and lays claim to the disputed territories of northern Iraq; these territories have a predominantly non-Arab population and were subject to the Ba'athist Arabization campaigns throughout the late 20th century. Though the KRI's autonomy was realized in 1992, one year after Iraq's defeat in the Gulf War, these northern territories remain contested between the Kurdistan Regional Government (in Erbil) and the Government of Iraq (in Baghdad) to the present day. The Kurdistan Region Parliament is based in Erbil, the capital of KRI.

Throughout the 20th century, Iraq witnessed multiple periods of instability and conflict that prompted the creation and flight of many refugees. Earlier examples include the exodus of Iraqi Jews and the flight of Iraqi Kurds. The Iraqi invasion of Iran in 1980 and the ensuing Iran–Iraq War (1980–1988) triggered a deterioration of ties among the country's various ethnic and religious communities, and also exacerbated in violent events like the Ba'athist Arabization campaigns in northern Iraq (1968–2003), which led to the killing and displacement of thousands of minorities. The Iraqi invasion of Kuwait (1990) and the ensuing Gulf War (1990–1991), which ended with Iraq's defeat and the application of United Nations sanctions (1991–2003), also resulted in the creation of many Iraqi refugees. It was not until the beginning of the ongoing Iraqi conflict, however, that sustained waves of Iraqi refugees would be created, numbering in the millions: the 2003 invasion of Iraq and the ensuing Iraq War (2003–2011) killed and displaced hundreds of thousands of Iraqis, both internally and externally, and the later War in Iraq (2013–2017) forced even more people to flee from the country. Many Iraqi refugees established themselves in urban areas of other countries rather than in refugee camps.

In April 2007, there were approximately four million Iraqi refugees around the world, including: 1.9 million within Iraq; two million in neighbouring Arab countries, as well as in Iran and Turkey; and approximately 200,000 outside of the Middle East entirely. The United Nations High Commissioner for Refugees (UNHCR) has led the humanitarian efforts for Iraqi refugees. The number of displaced persons and refugees from the Iraqi conflict is considered to be the largest in the Middle East, though this figure may now be lower than that of the refugees of the Syrian civil war.
