In Wyoming, a law was passed that prohibited the marriage of "pure white bloods" from marrying African Americans or mulattos. This was put into place to make sure blacks and whites were truly separated. Whites did not want to be associated with other whites that were not racist/ even though of falling in love with an African American. A similar law was passed in Colorado, but if the law was broken, the punishment included excessive fines or jail time. South Carolina, Louisiana, and Nebraska also had these laws put into place.
