Throughout its history, the region now known as South Dakota has experienced a series of significant migration waves, each influencing the cultural, economic, and demographic landscape of the state. Prehistoric peoples, often referred to as Paleo-Indians, established early human presence over ten thousand years ago. Subsequent centuries saw the growth and movement of diverse Native American nations, such as the Arikara, Mandan, Hidatsa, and later the Sioux (Lakota, Dakota, and Nakota). European fur traders, most notably of French-Canadian origin, entered the region in the eighteenth century, paving the way for larger waves of Euro-American settlers under federal acts like the Homestead Act of 1862. In the late nineteenth and early twentieth centuries, various European immigrant groups—including Scandinavians, Germans from Russia, and Hutterites—sought farmland and religious freedom. African American families arrived as part of broader social movements, while more recent decades have brought immigrants from Latin America, Asia, and Africa, each group drawn by employment prospects and resettlement programs.
