The Persian Empire was founded by Cyrus the Great who conquered Babylon in 536 BC. Cyrus issued the decree for the Jews to return to Jerusalem and rebuild the temple. Under Darius the second Temple of Zerubbabel was completed; and under Xerxes, or Ahasuerus, the events recorded in the Book of Esther in the Bible happened; under Artaxerxes the Jewish state was reformed by Ezra, and the walls of Jerusalem were rebuilt by Nehemiah. The capital of the Persian Empire was Shushan. The Empire lasted a little more than 200 years, and came to an end in 330 BC.
