History teaching is within the confines of a curriculum and under the pressure of examinations is riven with unfortunate compromises and unintended outcomes. The question of the civil rights movement in America is a case in point. Textbooks in the UK tend to focus on the 1950s and 1960s, centring mainly around the story of Martin Luther King and the civil rights movement in the south. The narrative becomes more complex after the passage of the Voting Rights ActVoting Rights Act voting-rights-act-1965 The 1965 US federal law that banned discriminatory voting practices, particularly literacy tests and other mechanisms used to disenfranchise Black voters in the South. Combined with federal oversight of state election laws, it produced a dramatic increase in Black voter registration and electoral participation that transformed Southern and national politics. President Johnson signed the Voting Rights Act on 6 August 1965, five months after ‘Bloody Sunday’ in Selma. The Act outlawed literacy tests and other qualifying devices that had been used to prevent Black voters from registering, authorised federal examiners to register voters in states with a history of discrimination, and — in Section 5, the ‘preclearance’ provision — required states and jurisdictions with histories of voting discrimination to obtain federal approval before changing any voting law or procedure. The immediate impact was dramatic: in Mississippi, Black voter registration rose from 6.7% in 1965 to 59.8% in 1967; across the South, hundreds of Black officials were elected to positions ranging from school board to state legislature within five years. Section 5’s preclearance requirement was the law’s most effective enforcement mechanism: it reversed the historical burden of proof, requiring jurisdictions with discriminatory histories to demonstrate that proposed changes would not discriminate rather than requiring plaintiffs to prove discrimination after the fact. The Supreme Court’s 2013 decision in Shelby County v. Holder gutted the preclearance requirement by voiding the coverage formula that determined which jurisdictions needed to seek approval, effectively suspending Section 5 and immediately triggering new voting restrictions in several states. The Voting Rights Act and its subsequent history demonstrate that legal protections for political rights require continuous institutional enforcement — that rights recognised in law but not actively defended are eroded by the political forces that benefit from their erosion. The Act’s five decades of success were possible partly because the preclearance mechanism imposed procedural barriers on restrictive legislation before it took effect, preventing discriminatory laws from disenfranchising voters while litigation slowly proceeded. The Shelby County decision removed this mechanism on the reasoning that the conditions justifying it no longer existed — a decision that critics argued was immediately disproven by the wave of new voting restrictions that followed. The deeper question the Act’s history poses is whether formal legal equality, even effectively enforced, is sufficient to address the structural political inequality produced by generations of disenfranchisement. 1965 and then after 1968 most text
