Ok so in reality King Xerxes was a powerful Persian Emperor who ruled over the Persian empire from 485 to 465 BC. He was the son of Darius the Great and a descendent of Cyrus the Great. He was not at all gay like depicted in the movie "300", that movie was so inaccurate. King Xerxes married Esther a Jewish young woman who saved many Jewish people during the persecution of Jews in Persian Empire. She pleaded with her husband to spare the lives of her people, the Jews and he did, giving them the right to defend themselves in his kingdom. The story of Queen Esther and King Xerxes can be read in the Bible or seen in the ACCURATE movie "One Night with the King."
King Xerxes is powerful enough to rule an empire with his eyes closed and hands tied behind his back.
