In her 1913 book on Baptist missionary history entitled, Following the Sunrise: A Century of Baptist Missions, 1813-1913 (Philadelphia, 1913), Helen Barrett Montgomery observes in a brief introduction to early Baptist work in Siam that, "The story of American Baptist missionary work in China, strangely enough, does not begin in China, but in Siam, where it is interwoven with the story of missions in Burma." (p. 146) Her observation highlights one of the most fascinating challenges facing those who "dabble" in the history of the Christian movement in Thailand, namely the way in which it connects to so much else in so many other places. Leaving aside whether or not the history of Protestant missions in China actually begins in Bangkok or not, the history of 19th century Baptist missions in Siam is tied to the development of Baptist missions in Burma and profoundly influenced by the opening of China to Protestant missions. In my own research on the Presbyterians, I have found myself repeatedly drawn into the orbit of other histories including even that of
British India, which bordered the northern Thai states in the era of the Presbyterian Laos Mission ("Laos" here referring to those northern states that were tributary to Siam, not modern-day Laos). For me, one of the most fascinating "cognate" fields of study for the history of the church in Thailand is Protestant missions history among the American Indians. Many of the themes are the same, the experiences are similar, and there was even at least one Presbyterian missionary, Jonathan Wilson, who first served out on the plains of the American West before he became a missionary in Siam and then in the North.
In an almost paradoxical way, then, the field of Thai Christian historical studies is an incredibly minor and modest field of immense, nearly global proportions. What fun!
