Assyrian nationalism is a movement of the Assyrian people that advocates for independence or autonomy within the regions they inhabit in northern Iraq, northeastern Syria, northwestern Iran, and southeastern Turkey.
The Assyrian people claim descent from those who established the Mesopotamian Assyrian civilization and empire which was centered in Ashur, modern day Iraq, which at its height, covered the Levant and Egypt, as well as portions of Anatolia, Arabia and modern-day Iran and Armenia. The empire lasted from perhaps as early as the 25th century BC until its collapse around 7th century BC.
The movement emerged in the late 19th century in a climate of increasing ethnic and religious persecution of the Assyrians in the Ottoman Empire, and is today commonly espoused by Assyrians in the Assyrian diaspora and Assyrian homeland.
The Unrepresented Nations and Peoples Organization (UNPO) recognizes Assyrians as an indigenous people of northern Iraq, southeastern Turkey, northeastern Syria and the fringes of northwestern Iran, as does the Political Dictionary of the Modern Middle East.
The ideology of Assyrian nationalism is based on the political and national unification of ethnic Assyrian followers of a number of Syriac Christian churches (mainly those originating in, or based in and around Upper Mesopotamia) with classical, Akkadian influenced Syriac as its cultural language and Eastern Aramaic dialects as spoken tongues. Its main proponents in the late 19th century and early 20th century were Naum Faiq, Freydun Atturaya, Ashur Yousif, Malik Khoshaba and Farid Nazha.
Within the Syriac Christian population in the near east as a whole, Assyrianism is confined specifically by certain geographic, ethnic, linguistic and confessional boundaries.
Geographically and linguistically, an Assyrianist position is held by those who speak Eastern Aramaic dialects who live or descend from those who once lived in northern Iraq, northeastern Syria, southeastern Turkey and northwestern Iran.
Theologically, the position is a little more complex.
