In late May 1904 a small band of people led by a certain Kasan Mukmin, a kyai or rural religious teacher, mounted an uprising in the village of Kebonpasar in Gedangan district of Sidoarjo regency, East Java. It was a single incident in a series of protests involving small groups of affluent peasants in Java between 1880 and 1920 which are difficult to explain in terms of the “moral economy” perspective. J.C. Scott has suggested that increasing intrusion of market economic forces into the indigenous economic life in the process of capitalist economic transformation eroded the subsistence margin of peasants instigating them to mount uprisings. This view may well explain some major peasant uprisings in Southeast Asia, but as Mukmin's uprising illustrates, numerous small rural protests in Java after 1880 occurred in relatively prosperous areas and involved affluent peasants. They were not caused by violation of peasants' perception of moral economy.
