Darius the Persian (Neh. 12:22) was probably the Darius II. (Ochus or Nothus) of profane history, the son of Artaxerxes Longimanus, who was the son and successor of Ahasuerus (Xerxes). There are some, however, who think that the king here meant was Darius III. (Codomannus), the antagonist of Alexander the Great (B.C. 336-331).
