British Assyrians are British people of Assyrian descent or Assyrians who have British citizenship. They are the indigenous pre-Arab, pre-Kurdish and pre-Turkic people of Mesopotamia (present-day northern Iraq, southeast Turkey, northwestern Iran, Syria) and nearby areas, which encompass the Assyrian homeland). They speak Syriac and are predominately Christian. Concentrations of Assyrians are found in Greenford and in Hanwell, both towns within the London Borough of Ealing. Assyrians in the UK and other western countries mostly migrated from Iran, Iraq, Jordan, and Syria. Migration was largely triggered by long standing ethnic and religious persecution in their homeland.
