The name of the act is the Voting Rights Act of 1965.
This act was the culmination of hard work and dedication by Civil Rights leaders like Martin Luther King Jr. This law, signed by President Lyndon B. Johnson, got rid of the literacy tests that stopped thousands, possibly even millions, of African-Americans from voting during the late 19th and early 20th century. The increase in African-American voter participation sky rocketed and allowed for millions of African-Americans to gain a voice in the political process.
