Voting Rights Act of 1965
Congress responded to rampant discrimination against racial minorities in public accommodations and government services by passing the Civil Rights Act of 1964. The Act included some voting rights protections; it required registrars to equally administer literacy tests in writing to each voter and to accept applications that contained minor errors, and it created a rebuttable presumption that persons with a sixth-grade education were sufficiently literate to vote. However, despite lobbying from civil rights leaders, the Act did not prohibit most forms of voting discrimination. President Lyndon B. Johnson recognized this, and shortly after the 1964 elections in which Democrats gained overwhelming majorities in both chambers of Congress, he privately instructed Attorney General Nicholas Katzenbach to draft "the goddamndest, toughest voting rights act that you can". However, Johnson did not publicly push for the legislation at the time; his advisers warned him of political costs for vigorously pursuing a voting rights bill so soon after Congress had passed the Civil Rights Act of 1964, and Johnson was concerned that championing voting rights would endanger his Great Society reforms by angering Southern Democrats in Congress.
Civil rights movement
From 1890 to 1908, southern states passed new constitutions and laws to disenfranchise African Americans and many poor whites by creating barriers to voter registration; voting rolls were dramatically reduced as blacks and poor whites were forced out of electoral politics. After the landmark Supreme Court case of "Smith v. Allwright" (1944), which prohibited white primaries, progress was made in increasing black political participation in the Rim South and Acadiana – although almost entirely in urban areas and a few rural localities where most blacks worked outside plantations. The "status quo ante" of excluding African Americans from the political system lasted in the remainder of the South, especially North Louisiana, Mississippi and Alabama, until national civil rights legislation was passed in the mid-1960s to provide federal enforcement of constitutional voting rights. For more than sixty years, blacks in the South were essentially excluded from politics, unable to elect anyone to represent their interests in Congress or local government. Since they could not vote, they could not serve on local juries.
