The Assyrian-Chaldean-Syriac diaspora (Syriac: ܓܠܘܬܐ, Galuta, "exile") refers to Assyrians living in communities outside their ancestral homeland. The Eastern Aramaic-speaking Assyrians are descendants of the ancient Assyrians, and are one of the few ancient Semitic ethnicities in the Near East who resisted Arabisation, Turkification and Islamisation during and after the Arab conquest of Iraq.
The indigenous Assyrian homeland is within the borders of northern Iraq, northeastern Syria, southeastern Turkey and northwestern Iran, a region roughly corresponding with Assyria from the 25th century BC to the seventh century AD. Assyrians are Semitic Christians; most are members of the Assyrian Church of the East, the Ancient Church of the East, the Chaldean Catholic Church, the Syriac Catholic Church, the Assyrian Pentecostal Church or the Assyrian Evangelical Church. The term "Syriac" can be used to describe Assyrians by their religious affiliation.
Before the Assyrian genocide, the Assyrian people were largely unmoved from their native lands which they had occupied for about five thousand years. Although a handful of Assyrians had migrated to the United Kingdom during the Victorian era, the Assyrian diaspora began in earnest during World War I as the Turkish army massacred and forcibly relocated the Assyrian people with the aid of local Kurdish, Iranian and Arab tribes.
