Iran is historically known as Persia. The Persian Empire was one of the greatest empires of the ancient world with a series of imperial dynasties. The empire also was frequently invaded, first by Alexander the Great, then by the Parthians, later ruled by the Hellenistic Seleucid Empire.

Iran's hereditary monarch, Shah Mohammad Reza Pahlavi, fled the country in 1979 after decades of corrupt and authoritarian rule, and mounting religious and political unrest. Exiled Ayatollah Ruhollah Khomeini returned from Paris to lead an Islamic revolution and formed the world's first Islamic republic the same year. An eight-year war with Iraq followed.
