This article discusses two Christian critiques of Islam published during the colonial era, and the response by the colonial government to each. The first goal of the article is to characterize Christian criticisms of Islam during the colonial era. The second is to demonstrate how conflict over Islam could shape relations between British administrators and Christian missionaries. The third goal is to narrate the history of a religious controversy as it developed over two generations. As will be seen, the war of words over government religious policy toward Islam could become quite vicious, even without any active participation by Muslims.
