 With the completion of the transcontinental railroad, and the recent indian skirmishes like 'The battles of Horseshoe Bend' and Jackson driving the Seminole out of Florida, and the Cherokee out of Georgian reserves with the addition of the Homestead Act of 1862, there was an extreme desire to populate the western frontiers that had already been somewhat settled by the Baptists/presbyterians/Methodists.
