Dárá continued the government of the empire in the same spirit as his father; claiming custom and tribute from the inferior rulers, with similar strictness and decision. After the death of Failakús, Sikander became the king of Rúm; and refusing to pay the demanded tribute to Persia, went to war with Dárá, whom he killed in battle; the particulars of these events will be presently shown. Failakús reigned twenty-four years.
