Cite as: 570 U. S. ____ (2013) 3 Opinion of the Court Mississippi, North Carolina, South Carolina, and Virginia began to enact literacy tests for voter registration and to employ other methods designed to prevent AfricanAmericans from voting. Katzenbach, 383 U. S., at 310. Congress passed statutes outlawing some of these practices and facilitating litigation against them, but litigation remained slow and expensive, and the States came up with new ways to discriminate as soon as existing ones were struck down. Voter registration of African-Americans barely improved. Id., at 313–314. Inspired to action by the civil rights movement, Congress responded in 1965 with the Voting Rights Act.
