North Dakota and South Dakota

Definition and stakes

The New Student's Reference Work (1914)

In 1849 North Dakota east of the Missouri became part of Minnesota for a time, and the area west of the river was made a part of Nebraska Territory. In 1851 to the Federal government was ceded part of the lands held by the Sioux Indians, and these lands were thrown open for settlement. In 1861 Dakota Territory was created, part of Montana and part of Wyoming being included in it; while two years later, on the creation of Idaho Territory, the Dakotas assumed almost their present area, and in 1889 they were separated, forming North Dakota and South Dakota.

This frequently does not result in a well-balanced permanent population, and the real settlement of South Dakota dates from the succeeding period when its prairie lands were taken up by wheat growers from the States of the upper Mississippi Valley. The wheat industry in Wisconsin gradually died during the decade of 1870-80, and many who found the ground unprofitable there moved farther west, as did others with similar motives from western New York and the States of the old Northwest Territory.

The leaders of that period believed that it would be a crime for them to sit idly by and permit the great territory to become one state, with but two members of the United States Senate, thus entailing to posterity forever a sort of political vassalage to the small states of the eastern seaboard. Besides this there was at that period an inherent difference between the people of South Dakota and those of the North. South Dakota was chiefly occupied by homesteaders, who brought with them the conservative notions of small farmers, about public and private economy, morality, and education.
