On the night of 9–10 July 1980, several hundred active-duty and retired Iranian paratroopers made their way to the Nuzhih air-force base near the city of Hamadan to initiate a coup d'état against Iran's fledgling Islamic regime. The Iranian government had learned of the plot, and many of the paratroopers were arrested as they arrived at the base. Several hundred additional participants in the plot were arrested in the following days. Those arrested were soon put on trial, and many were executed. Fearing that other military personnel were linked to the plot or sympathized with it, the government carried out an extensive purge of the armed forces in the following months. Hundreds of other participants in the plot were never apprehended, however, and many continued to plot against the Islamic regime, though they never again posed a serious threat to it.
