During the 1970's, Shah Mohammad Reza Pahlavi, who had acceded to the monarchist governmental leadership role present throughout Iran's history, implemented economic, educational and social reforms. In 1978, in the midst of democratic reforms, the Shah and the Iranian people celebrated 2,500 years of Persian Monarchy. Thereafter, the Carter Administration, awkwardly wielding a contorted rhetoric of "human rights" thoughtlessly encouraged the overthrow of the Shah and thereby hastened the arrival of an exiled and obscure cleric Ayatollah Khomeini, and with him the Islamic Republic of Iran.
