A chronological account of all known church or denominational missionary efforts among the Sioux peoples. The author grew up among them, as his parents were Baptist missionaries to the Lakota Sioux Indians on the Pine Ridge Indian Reservation. His parents began their missionary work in 1950 and stayed for 52 years.
"This book on religion and missionary work among the Sioux Indians was begun as a chart for a college research paper at Tabor College in Hillsboro, Kansas, in the spring semester of 1964. Due to the interest shown in such a project, I decided to get as complete as picture a possible of all of the missionary work done among the Sioux Indians by all church denominations or religious organizations up to and including the year 1965, which was three hundred years after the first recorded missionary work done among the Sioux Indians. This book has been written to show what was done by each church denomination or religious organization in chronological form giving the year that each event happened. It was also written for the benefit of these church denominations or religious organizations, especially to help promote the need for missionary work among the Sioux Indians by the fundamental Bible believing churches." - Author's preface.
