 From 1890 to 1908, Southern states accomplished disenfranchisement of blacks and—in some states—many poor whites.During the first three decades of the 20th century, no blacks served in the U.S. Congress due to their disenfranchisement across the South.Black leaders were barred in 1922 from the Virginia Republican Congressional Convention; the state had imposed racial segregation in public places and disenfranchised most blacks by this time.
