British Missionaries and Imperial States, 1870-1918

The authors examine the interaction of missionary organizations with local political powers and with their home government, arguing that in trying to decide which course of action to pursue, missionaries became knowledgeable students of imperial politics and the shifting state of international affairs. They show that leadership of British missionary societies was split between those who wanted to be treated without favouritism by the British government and those who had more aggressive expectations. In doing so they explore the pressures that contributed to the formation of imperial policy and perspective during a significant period of the evolution of the British empire.
