A caucus is a meeting of supporters or members of a specific political party or movement. The exact definition varies between different countries and political cultures.
The term originated in the United States, where it can refer to a meeting of members of a political party to nominate candidates, plan policy, etc, in the United States Congress, or other similar representative organs of government. It has spread to certain Commonwealth countries, including Australia, Canada, New Zealand and South Africa, where it generally refers to a regular meeting of all members of Parliament who belong to a parliamentary party: in such a context, a party caucus can be quite powerful, as it has the ability to elect or dismiss the party's parliamentary leader. The term was used historically in the United Kingdom to refer to the Liberal Party's internal system of management and control.
The word caucus first came into use in the British colonies of North America, in reference to clubs or private meetings at which political matters were discussed.
The Boston Gazette of May 5, 1760, includes the statement: "It is reported, that certain Persons ... are called by the Name of the New and Grand Corcas."
A February 1763 entry in the diary of John Adams demonstrates that the word already held its modern connotations of a "smoke-filled room" where candidates for public election were pre-selected in private:
This day learned that the Caucas Clubb meets at certain Times in the Garret of Tom Daws, the Adjutant of the Boston Regiment. He has a large House, and he has a moveable Partition in his Garrett, which he takes down and the whole Clubb meets in one Room. There they smoke tobacco till you cannot see from one End of the Garrett to the other. There they drink Phlip I suppose, and there they choose a Moderator, who puts Questions to the Vote regularly, and Selectman, Assessors, Collectors, Wardens, Fire Wards, and Representatives are Regularly chosen before they are chosen in the Town ...
Similarly, William Gordon wrote in 1788:
The word caucus, and its derivative caucusing, are often used in Boston […] It seems to mean, a number of persons, whether more or less, met together to consult upon adopting or presenting some scheme of policy, for carrying a favorite point. The word is not of novel invention. More than fifty years ago, Mr. Samuel Adams's father, and twenty others, one or two from the north end of the town, where all the ship business is carried on, used to meet, make a caucus, and lay their plan for introducing certain persons into places of trust and power.
However, the word's origins remain uncertain. There are three main theories:
An analogical Latin-type plural "cauci" is occasionally used.
In United States politics and government, caucus has several distinct but related meanings. Members of a political party or subgroup may meet to coordinate members' actions, choose group policy, or nominate candidates for various offices.
There is no provision for the role of political parties in the United States Constitution. In the first two presidential elections, the Electoral College handled nominations and elections in 1789 and 1792 which selected George Washington. After that, Congressional party or a state legislature party caucus selected the party's presidential candidates. Nationally, these caucuses were replaced by the party convention starting in 1832 following the lead of the Anti-Masonic Party 1831 convention.
The term caucus is frequently used to discuss the procedures used by some states to select presidential nominees such as the Iowa caucuses, the first of the modern primary presidential election cycle, and the Texas caucuses. Since 1980 such caucuses have become, in the aggregate, an important component of the nomination process.
Main article: Congressional caucus
Another meaning is a sub grouping of officials with shared affinities or ethnicities who convene, often but not always to advocate, agitate, lobby or to vote collectively, on policy. At the highest level, in Congress and many state legislatures, Democratic and Republican members organize themselves into a caucus (occasionally called a "conference"). There can be smaller caucuses in a legislative body, including those that are multi-partisan or even bicameral. Of the many Congressional caucuses, one of the best-known is the Congressional Black Caucus, a group of African-American members of Congress. Another prominent example is the Congressional Hispanic Caucus, whose members voice and advance issues affecting Hispanics in the United States, including Puerto Rico. In a different vein, the Congressional Internet Caucus is a bipartisan group of Members who wish to promote the growth and advancement of the Internet. Other congressional caucuses such as the Out of Iraq Caucus, are openly organized tendencies or political factions (within the House Democratic Caucus, in this case), and strive to achieve political goals, similar to a European "platform", but generally organized around a single issue.
The term is also used in certain Commonwealth nations, including Australia, Canada, New Zealand and South Africa. However, when used in these countries, "caucus" is more usually a collective term for all members of a party in Parliament, otherwise called a parliamentary group, rather than a word for a regular meeting of these Members of Parliament. Thus, the Australian Federal Parliamentary Labor Party is commonly called "the Labor Caucus".
The word was used in New Zealand from at least the 1890s, when organized political parties began to emerge: the largest of them, the Liberal Party, used it to refer to its parliamentary members. It was introduced to Australia in 1901 by King O'Malley, an American-born Labour member of the first Federal Parliament.
In New Zealand, the term is now used by all political parties, but in Australia, it continues to be used only by the Labor Party. For the Australian Liberal, National and Green parties, the usual equivalent term is "party room". In South Africa all parties use the term "caucus". In Canada, "caucus" refers to all members of a particular party in Parliament, including senators, or a provincial legislature. These members elect among themselves a caucus chair who presides over their meetings. This person is an important figure when the party is in opposition, and is an important link between cabinet and the backbench when the party is in government.
In such contexts, a party caucus can be quite powerful, as it can elect or dismiss the party's parliamentary leader. The caucus system is a departure from the Westminster tradition in giving members of the upper house a say in the election of the party leader, who may become head of government. The caucus also determines some matters of policy, parliamentary tactics, and disciplinary measures against disobedient MPs. In some parties, the caucus also has the power to elect MPs to Cabinet when the party is in government. For example, this is traditionally so in the Australian Labor Party and the New Zealand Labour Party.
In contrast to other Anglosphere nations, the term is never used for all members of a party in the United Kingdom Parliament: the usual term for that concept, both in the UK and in the Republic of Ireland, is "parliamentary party".
On the rare occasions when the term "caucus" is encountered in modern UK politics, it is generally used to mean a subgroup, faction or pressure group within a political party in a similar manner to congressional caucuses in the United States. For example, in 2019 the One Nation Conservatives and Blue Collar Conservatives were established as factions within the Conservative Party, both being described as "caucuses".
The word "caucus" had a wide currency in the UK in the late 19th century, in reference to a highly structured system of management and control within a political party, specifically the Liberal Party. It was originally a pejorative term, used by detractors of the system with overtones of corrupt American practices; but the name was soon adopted by the Liberals themselves.
The system had originated at a local level in Birmingham in preparation for the 1868 general election, when, under the 1867 Reform Act, the city had been allocated three parliamentary seats, but each elector had only two votes. In order to spread votes evenly, the secretary of the Birmingham Liberal Association, William Harris (later dubbed the "father of the Caucus") devised a four-tier organizational structure (of ward committees, general committee, executive committee, and management committee) through which Liberal voters in different wards could be instructed in the precise combinations in which to cast their votes. In 1877 the newly formed National Liberal Federation was given a similar structure, on the initiative of Joseph Chamberlain, and again worked out in detail by Harris.
Shortly afterwards the term "caucus" was applied to this system by The Times newspaper, which referred to "the 'caucus' with all its evils", and by the Conservative prime minister, Benjamin Disraeli. In 1880 Queen Victoria, following a meeting with Disraeli, wrote disapprovingly in a private note of "that American system called caucus". The Liberal Caucus was also vilified by socialists and trade unionists, who (prior to the establishment of the Independent Labour Party) sought a route to parliamentary representation through the Liberal Party via the Labour Representation League and the Labour Electoral Association, but found their way barred by the party's management structures.
Moisey Ostrogorsky devoted some nine chapters of his Democracy and the Organization of Political Parties (1902) to discussion of the development and operation of the "Caucus" in this sense.
In conventions, where the membership from different parts of the organization may gather, each separate group within the organization may meet prior to the convention as a caucus. Each caucus may decide how the group would vote on various issues that may come up at the convention. Unless the votes are made binding, however, each delegate is still free to vote in any fashion.
The term caucus is also used in mediation, facilitation and other forms of alternative dispute resolution to describe circumstances wherein, rather than meeting at a common table, the disputants retreat to a more private setting to process information, agree on negotiation strategy, confer privately with counsel or with the mediator, or simply gain "breathing room" after the often emotionally difficult interactions that can occur in the common area where all parties are present. The degree to which caucuses are used can be a key defining element, and often an identifier, of the mediation model being used. For example, "facilitative mediation" tends to discourage the use of caucuses and tries to keep the parties talking at a single table, while "evaluative mediation" may allow parties to separate more often and rely on the mediator to shuttle information and offers back and forth.
As one of its number points out, the Blue Collar group of Conservative MPs is bigger than almost any other caucus in the parliamentary party, including the One Nation bloc of self-styled moderates.
There is to be a sort of Liberal Parliament organized, which, in American language, seems intended to act as a great Liberal 'Caucus'.
... what the Times calls the new Liberal Caucus ...
We may say, and say truly, that the policy of the politicians of the Midland capital will bring upon us the 'caucus' with all its evils, but we cannot hope to checkmate it by giving it a bad name. The apologists of the system will tell us that the 'caucus' is a product of the peculiar conditions of life in America, which need not be apprehended in a society of totally different circumstances
I observe that you, in common with the Prime Minister, have adopted the word 'caucus' to designate our organization.
... the word ['caucus'] chosen by the Prime Minister to describe [the Liberals'] system, and eagerly caught up by lesser critics ... conveys the idea of secrecy and irresponsibility ...
That the Liberals had worked on that American system called caucus, originated by the great Radical, Mr Chamberlain.
