Hijab has been a very controversial issue in Iran for nearly ninety years. The founder of Iran's Pahlavi dynasty, Reza Shah, banned the hijab in January 1939 despite the strong opposition by clerics but a few years later under his son Mohammad Reza Shah Pahlavi the ban fell into oblivion. Only five months after the Islamic Revolution of 1979, then leader of Iran Ayatollah Ruhollah Khomeini banned hijablessness in government offices. The ban gradually spread to the entire society within the next two years.
