There were several reasons why the bazaar class worked hard to help advance the revolution. The government of Mohammed Reza Pahlavi was anathema to the bazaaris, who seemed set to lose out as the country was being industrialized, and they feared that they would be left behind and their status in society would be reduced. Similarly, another concern for the bazaar class, not just in Tehran but throughout Iran, was that these traditional economic forces did not benefit from the 1974–1978 oil boom, and were thus even more inclined to aid the revolution.
