The Boston Globe, Christian Science Monitor, and Washington Post have dubbed it a “Twitter Revolution,” speculating about whether new technology will enable Iranian protesters to overcome government forces. The role of technology in the current unrest is well-covered elsewhere. What is lacking in much of the coverage, however, is a sense of context.

Technology has been essential both to empire formation and preservation, and to state degradation in the Middle East. The late historian Marshall G.S. Hodgson described the Ottoman, Safavid, and Mughal Empires as “gunpowder empires.” Their sultans and shahs consolidated control over expansive territories by controlling weaponry which potential aspirants to power along the periphery did not have. Once the central government lost monopoly over guns and cannons, however, the empires fractured–devolving into fiefdoms or dissolving completely.

In Iran, technology played a particularly important role in state preservation Looking at 18th and early 19th century atlases, borders are all over the place. Discrepancies of dozens if not hundreds of miles mark frontiers on maps published by different gazetteers. Whereas today imperialism is presented in almost cartoonish terms as a free-for-all, in reality there were huge debates during the 19th century whether or not to expand imperial control over various territories. Imperial rule was an expensive prospect, and so many imperial powers preferred to advance informal control.
