The Shah of Iran visited Miami, Florida with his second wife Soraya in the late 1970s. The Shah's regime in Iran was overthrown in 1979 by the Iranian Revolution, replacing the monarchy with an Islamic republic under the leadership of Ayatollah Khomeini. History showed that not understanding past events can lead to those events repeating, as the circumstances in Iran that led to the overthrow of the Shah's government were again present in the late 1970s.
