Following the 1979 Islamic revolution in Iran in 1981, the Bahraini Shia population orchestrated a failed coup attempt under the auspices of a front organisation, the Islamic Front for the Liberation of Bahrain. The coup would have installed a Shia cleric exiled in Iran, Hujjatu l-Islām Hādī al-Mudarrisī, as supreme leader heading a theocratic government. In December 1994, a group of youths threw stones at female runners for running bare-legged during an international marathon. The resulting clash with police soon grew into civil unrest.
