The area of the world once home to the Persian Empire has seen its fair share of social and political turbulence. In 1979, the western-supported ruler Shah Mohammad Reza Pahlavi was overthrown during the Iranian Revolution, and a conservative Islamic cleric named Ayatollah Ruhollah Khomeini came to power and formed an Islamic republic. This system of government still remains even after Khomeini's passing in 1989, with Ali Khamenei succeeding him as supreme leader of the country.
