Increasing Western influence in Asia saw Christian missionaries travel to the region to proselytize, which led them into conflict with various Asian governments over the tensions caused by the introduction of Christianity. In China, the activities of Western missionaries indirectly led to the Taiping Rebellion, as Christian rebels led by Hong Xiuquan revolted against the Qing government. In response to these developments and what Joseon royalty perceived as a subversive religion, regent Heungseon Daewongun initiated a series of persecutions of Korean Christians in 1866 in which 8,000 were killed, including several French missionaries. In response, the French dispatched an unsuccessful expedition to Korea, which reaffirmed Korean isolationism.
