Arbela, the ancient name of Arbil or Erbil, a small village in Turkish Kurdistan, which lies on the usual route between Bagdad and Mosul, about 40 m. E. by S. of the latter city, in lat. 36° 11' N., according to the elder Niebuhr's observations. The third and last of the great battles between Alexander and Darius (331 B. C.) is called after this place, though it was not actually fought at Arbela, but at a place 36 m. W. by N. called Gaugamela, now Karmelis.
