The Assyrian diaspora (Syriac: ܓܠܘܬܐ, romanized: Galuta, lit. 'exile') refers to ethnic Assyrians living in communities outside their ancestral homeland. The Eastern Aramaic-speaking Assyrians claim descent from the ancient Assyrians and are one of the few ancient Semitic ethnicities in the Near East who resisted Arabization, Turkification, Persianization and Islamization during and after the Muslim conquest of Iraq, Iran, Syria and Turkey.
The indigenous Assyrian homeland is within the borders of northern Iraq, southeastern Turkey, northwestern Iran, and northeastern Syria, a region roughly corresponding with Assyria from the 25th century BC to the 7th century AD. Assyrians are predominantly Christians; most are members of the Assyrian Church of the East, the Ancient Church of the East, the Chaldean Catholic Church, the Syriac Orthodox Church, the Syriac Catholic Church, the Assyrian Pentecostal Church and the Assyrian Evangelical Church. The terms "Syriac", "Chaldean" and "Chaldo-Assyrian" can be used to describe ethnic Assyrians by their religious affiliation, and indeed the terms "Syriac" and "Syrian" are much later derivatives of the original "Assyrian", and historically, geographically and ethnically originally meant Assyrian (see Name of Syria).
