Civil Rights Act of 1866
The Civil Rights Act of 1866, , enacted April 9, 1866, was the first United States federal law to define citizenship and affirm that all citizens are equally protected by the law. It was mainly intended, in the wake of the American Civil War, to protect the civil rights of persons of African descent born in or brought to the United States. This legislation was passed by Congress in 1865 and vetoed by U.S. President Andrew Johnson. In April 1866 Congress again passed the bill to support the Thirteenth Amendment. Johnson again vetoed it, but a two-thirds majority in each chamber overcame the veto to become law without presidential signature.
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.
