What Is a Filibuster in Congress? Definition and Examples in Government

A filibuster in Congress is a legislative tactic used primarily in the United States Senate to delay or block a vote on a bill by extending debate. One notable example occurred in 1957 when Senator Strom Thurmond conducted the longest solo filibuster, speaking for over 24 hours to oppose the Civil Rights Act. This tactic demonstrated the power individual senators have to affect legislative progress through prolonged speeches. Filibusters rely on the Senate's unique rules that allow unlimited debate unless a supermajority invokes cloture to end it. Data shows that between 1917 and 2020, over 300 filibusters have taken place, significantly influencing policy outcomes. The practice highlights tensions within government entities where minority interests seek leverage over majority rule in lawmaking processes.
