Darius was the third Persian ruler after Cyrus the Great. Darius was very instrumental to the building of the temple in Jerusalem, by the sixth year of this reign the second Temple had been completed after permission had been earlier given about 16 years ago by Cyrus but there wasn't action to match this permission Darius allowed the construction to proceed against all odds and not only did he do that, he also helped the construction efforts along by providing resources from his royal treasury.
