In the years after the Islamic Revolution of 1979, thousands of people were sentenced to be shot for political offenses, drug trafficking, and crimes against the Islamic Republic by the newly established Revolutionary Courts. These included many of the Shah's former ministers, such as former Prime Minister Amir Abbas Hoveida, and the head of SAVAK General Nematollah Nassiri. By 1980, one year after the Shah had been overthrown, over 700 people had been shot by the new Islamic Republic. Many of the members of the former regime are suspected to have been unjustly executed in biased trials. A campaign against drug trafficking resulted in the executions of many for drug possession, including addicts, often based on minimal evidence. Some of these people were also alleged opponents of the regime. Many executions also took place after the Kurdistan revolt of 1979–1980.
