This call came after the Iranian Revolution that took place in Iran in 1979. This revolution led to the establishment of an islamic government in Iran. It also led the religious leaders of the country to call others in order to establish Islamic republics. One of the consequences of this change was the war with Iraq. Iraq invaded Iran on September 22, 1980. The main motivation was Iraq's fear that the dominant leaders of the Iranian Revolution would become a threat to the Iraqi regime.
