Anti-miscegenation cases in the American West
Anti-miscegenation cases in the American West were legal cases in which the government attempted to interfere with marriages between people of different racial, ethnic, or political backgrounds in the American West. During the fur trade of the 18th and early 19th century, White European trappers and traders often married into Indigenous nations.
