United States Senate breaks a 75-day filibuster against the Civil Rights Act of 1964, leading to the bill's passage.

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 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".
