Assyrians are an indigenous ethnic group native to Mesopotamia, a geographical region in West Asia. Modern Assyrians descend directly from Ancient Mesopotamians such as ancient Assyrians and Babylonians. Modern Assyrians may culturally self-identify as Syriacs, Chaldeans, or Arameans for religious, geographic, and tribal identification.
