The American Board began its work among the Dakotas in 1835. It was one of the most powerful tribes on the continent, numbering over 40,000. Their hunting-grounds extended from the 43 degrees to the 49 degrees of latitude, and from the Mississippi River to the Black Hills west of the Missouri. This was a territory equal in extent to that of Scotland. The name Dakota means the “allied one,” and indicates the bands that united to form the tribe.

They were incarcerated at the Mankato prison in Minnesota, where thirty-eight were hung in one day. The remainder in prison were visited by the missionaries, and the prison house became a chapel. Soon it was a Bethel, a great revival began, which lasted all winter, and in the spring, two hundred Dakotas
