The work of building the temple at Jerusalem, which had been but nominally commenced in the reign of Cyrus, when it was suddenly arrested before the death of that king, and which had not been touched throughout the reigns of the two succeeding kings, Cambyses and Pseudo-Bardes, was taken up in earnest in the second year of Darius, the son of Hystaspes (B.C. 521). The disorders of the empire were then favourable to local liberty. Cambyses committed suicide during a revolt of his army on the march to meet the Pretender who had assumed the name of his murdered brother, Bardes. Seven months later the usurper was assassinated in his palace by some of the Persian nobles. Darius, who was one of the conspirators, ascended the throne in the midst of confusion and while the empire seemed to be falling to pieces. Elam, the old home of the house of Cyrus, revolted; Syria revolted; Babylon revolted twice, and was twice taken by siege. For a time the king's writ could not run in Palestine. But it was not on account of these political changes that the Jews returned to their work. The relaxing of the supreme authority had left them more than ever at the mercy of their unfriendly neighbours. The generous disposition of Darius might have led them to regard him as a second Cyrus, and his religion might have encouraged them to hope that he would be favourable to them, for Darius was a monotheist, a worshipper of Ormazd. But they recommenced their work without making any appeal to the Great King and without receiving any permission from him, and they did this when he was far too busy fighting for his throne to attend to the troubles of a small, distant city.
