The Grand Bazaar (Persian: بازار بزرگ Bāzār-e Bozorg) in Tehran, Iran, is split into several corridors that are over 10 kilometres (6.2 mi) in length, each specializing in different types of goods.

However, under the reign of Reza Shah, as Tehran began to grow and reform exponentially in the early 20th century, the changes brought by this rapid development saw much of the bazaar disappear.

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.

The Grand Bazaar continues largely to support the establishment, particularly as conservative political forces often adopt a low tax, laissez-faire approach to the bazaaris.
