The Civil Rights Act of 1964 is approved after surviving an 83-day filibuster in the United States Senate.

The Civil Rights Act of 1964 is a landmark civil rights and labor law in the United States that outlaws discrimination based on race, color, religion, sex, and national origin. It prohibits unequal application of voter registration requirements, racial segregation in schools and public accommodations, and employment discrimination. The act "remains one of the most significant legislative achievements in American history".

A filibuster is a parliamentary procedure in which one or more members of a legislative body prolong debate on proposed legislation so as to delay or entirely prevent a decision. It is sometimes referred to as "talking a bill to death" or "talking out a bill", and is characterized as a form of obstruction in a legislature or other decision-making body.

The United States Senate is a chamber of the bicameral United States Congress; it is the upper house, with the U.S. House of Representatives being the lower house. Together, the Senate and House have the authority under Article One of the U.S. Constitution to pass or defeat federal legislation.
