The U.S. Congress enacted major amendments to the Voting Rights Act of 1965 in 1970, 1975, 1982, 1992, and 2006. Each of these amendments coincided with an impending expiration of some of the Act's special provisions, which originally were set to expire by 1970. However, in recognition of the voting discrimination that continued despite the Act, Congress repeatedly amended the Act to reauthorize the special provisions.

The Leadership Conference on Civil and Human Rights is an American coalition of more than 240 national civil and human rights organizations and acts as an umbrella group for American civil and human rights. Founded as the Leadership Conference on Civil Rights (LCCR) in 1950 by civil rights activists Arnold Aronson, A. Philip Randolph, and Roy Wilkins, the coalition has focused on issues ranging from educational equity to justice reform to voting rights.
