Civil Rights Act

The Civil Rights Act of 1964 was the single most important piece of legislation passed by Congress in American history. It gave the government sweeping powers to strike down segregation, to enforce fair hiring practices, and to rectify bias in law enforcement and in the courts. The Act so dramatically altered American society that, looking back, "it seems preordained", as Everett Dirksen, the GOP leader in the Senate and a key supporter of the bill, said, "no force is more powerful than an idea whose time has come." But there was nothing predestined about the victory.

On June 25, 2013, the US Supreme Court handed down its decision in Shelby County v. Holder, invalidating a key provision of voting rights law. The decision - the culmination of an eight-year battle over the power of Congress to regulate state conduct of elections - marked the closing of a chapter in American politics. That chapter had opened a century earlier in the case of Guinn v. United States, which ushered in national efforts to knock down racial barriers to the ballot.
