DEIOCES, the founder of the Median empire, flourished towards the close of the eighth century B.C. On the destruction of Sennacherib and his army under the walls of Jerusalem, the nations which till that time had owned allegiance to the Assyrians revolted, and among them the Medes. Deioces, whose love of justice had already made him distinguished in his own village, was appointed ruler of the new kingdom, and founded the Median dynasty, which lasted for 150 years. Deioces died after a peaceful reign of 35 years.
