Susa was the ancient capital of the Elamite Empire. It was located about 150 miles north of the Lower Sea (Persian Gulf) near the base of the Zagros Mountains. Susa was one of royal cities during the Persian Empire.

The Bible mentions three people in relation to Susa:

1) At Susa Esther was elevated to Queen of Persia (Esther 1:1-2:17) in the days of Ahasuerus (Xerxes I)

2) At Susa Nehemiah served as cupbearer to Artaxerxes I when he received the news about the walls of Jerusalem (Neh 1:1)

3) At Susa Daniel had a vision about the coming invasions by Persia and Greece (Dan 8:2)
