In particular, Plecker resented African Americans who passed as Native Americans, and he came to firmly believe that the state's Native Americans had been "mongrelized" with its African American population. In fact, since shortly after the Civil War, Native Americans from all over the country had been brought to the Hampton area to be educated with blacks, and some of them had also married blacks, although Hampton's Indian schools had closed down as racial discrimination against Native Americans and the eugenics movement both grew in the state. Plecker refused to recognize the fact that many mixed-race Virginia Indians had maintained their culture and identity as Native Americans over the centuries despite economic assimilation. Plecker ordered state agencies to reclassify most citizens who claimed American Indian identity as "colored", although many Virginian Native Americans continued to live in their communities and maintained their tribal practices. Church records, for instance, continued to identify them as Native Americans. Specifically, Plecker ordered state agencies to reclassify certain families whom he identified by surname, because he decided that they were trying to pass and evade segregation. This remained legal in the South until federal legislation overturned it in the 1960s.
