filibuster

Etymology

Borrowed from Spanish filibustero (“pirate”), from French flibustier, ultimately from Dutch vrijbuiter (“freebooter”), from vrij (“free”) + buit (“booty”) + -er (“agent”). The alteration in the first syllable in French is due to the word's being somewhat conflated with vlieboot (“light, flat-bottomed cargo vessel with two or three masts”) when it was borrowed into French or another language from Dutch. The word is cognate and analogous to English freebooter.

noun

1. A mercenary soldier; a freebooter; specifically, a mercenary who travelled illegally in an organized group from the United States to a country in Central America or the Spanish West Indies in the mid-19th century seeking economic and political benefits through armed force.
   These duties involved prodigious physical and mental exertion, in a climate deadly to Europeans. They also involved much voyaging in waters haunted by filibusters and buccaneers. But nothing appears to daunt Labat. As for the filibusters, he becomes their comrade and personal friend;—he even becomes their chaplain, and does not scruple to make excursions with them. 1890, Lafcadio Hearn, Two Years in the French West Indies, New York, N.Y.: Harper & Bros., →OCLC
   Mexico's War of Independence (1810–1821) encouraged an increase in the activity of filibusters in northern Mexico, particularly Texas. Spain's concentration on repressing independence movements within Mexico created opportunities for filibusters to seize control of its northern frontier regions. 2002, E. John Gesick, Jr., “Filibusters”, in Lee Stacy, editor, Mexico and the United States, volumes 1 (Acapulco, Guererro – Film in Mexico), Tarrytown, N.Y.: Marshall Cavendish, page 307, column 1
   Filibusters were American citizens who used armed force to procure economic and political influence beyond the borders of the United States from 1848–1861. Their efforts were directed mainly southward toward Cuba, Mexico, and the Central American republics. These illegal excursions disrupted diplomatic relations of the United States within its own hemisphere by damaging relations with Latin American countries and the United Kingdom. 2012, William H. Brown, “Central America, Filibusters”, in Thomas M. Leonard, editor, Encyclopedia of U.S.–Latin American Relations, volumes 1 (A–E), Thousand Oaks, Calif.: CQ Press; London: SAGE Publications, pages 149, column 2 – 150, column 1
   As they attempted to use the international press to their advantage, the filibusters were eager to counter any articles they perceived as misrepresenting their actions. […] [T]he filibusters took issue with what they called the "Boletinero de Costarica" and its outspoken condemnation of the filibuster presence in Nicaragua. […] Costa Rican periodicals were especially scorned by the filibusters for their constant rallying cries against the US usurpers. 2016, Andreas Beer, “The Nicaraguan Press and El Nicaraguense”, in A Transnational Analysis of Representations of the US Filibusters in Nicaragua, 1855–1857, New York, N.Y.: Palgrave Macmillan, →DOI, pages 95–96
2. (US politics) A tactic (such as giving long, often irrelevant speeches) employed to delay the proceedings of, or the making of a decision by, a legislative body, particularly the United States Senate.
   No longer do filibustering Senators take the floor and speak until they are physically unable to filibuster any longer. Now, a filibuster typically begins when a Senator or group of Senators signals their intent to filibuster – which can be done by a private conversation with the majority leader or by quietly placing a bill or nomination on hold. Given the modern Senate's scarce floor time, this threat is usually enough to table the disputed issue until the dissenting Senators cave or until there are definitely enough votes to invoke cloture. 22 April 2010, Mimi Murray Digby Marziani, Diana Lee, “Statement for the Record, Brennan Center for Justice, New York, NY”, in Examining the Filibuster: Hearings before the Committee on Rules and Administration, United States Senate, One Hundred Eleventh Congress, Second Session, April 22, 2010, May 19, 2010, June 23, 2010, July 28, 2010, and September 22 and 29, 2010 (S.

   According to U.S. law, filibustering was a violation of the Neutrality Law of 1818, which prohibited the organization within the United States of any armed force that intended to attack a friendly foreign power. The American government attempted, through the enforcement of this law, to prevent its citizens from filibustering, mostly by preventing potential filibustering groups from organizing and collecting arms for future operations. 2012, William H. Brown, “Central America, Filibusters”, in Thomas M. Leonard, editor, Encyclopedia of U.S.–Latin American Relations, volumes 1 (A–E), Thousand Oaks, Calif.: CQ Press; London: SAGE Publications, page 150, column 2
