The main way to end a filibuster is through cloture, first defined in 1917 as a two-thirds majority vote of the Senate, but later revised in 1975 to require only 60 votes. The cloture rule was established at the urging of President Woodrow Wilson.
Senate rules first allowed filibusters in 1806, but the term was not popular until the 1850s. The filibuster rule was initially intended to ensure minority opinions were heard before the Senate voted on an issue. The Senate first invoked cloture in 1919 to end a filibuster against the Treaty of Versailles. Filibusters were also used to delay votes on the Civil Rights Acts of 1957 and 1964.
