History


Origins in the French Revolution

The terms "left" and "right" first appeared during the French Revolution of 1789 when members of the
National Assembly In politics, a national assembly is either a unicameral legislature, the lower house of a bicameral legislature, or both houses of a bicameral legislature together. In the English language it generally means "an assembly composed of the repr ...

to the president's right and supporters of the revolution to his left. One deputy, the Baron de Gauville, explained: "We began to recognize each other: those who were loyal to religion and the king took up positions to the right of the chair so as to avoid the shouts, oaths, and indecencies that enjoyed free rein in the opposing camp". When the National Assembly was replaced in 1791 by a Legislative Assembly composed of entirely new members, the divisions continued. "Innovators" sat on the left, "moderates" gathered in the centre, while the "conscientious defenders of the constitution" found themselves sitting on the right, where the defenders of the Ancien Régime had previously gathered. When the succeeding

met in 1792, the seating arrangement continued, but following the coup d'état of 2 June 1793 and the arrest of the Girondins, the right side of the assembly was deserted and any remaining members who had sat there moved to the centre. Following the Thermidorian Reaction of 1794, the members of the far left were excluded and the method of seating was abolished. The new constitution included rules for the assembly that would "break up the party groups". Following the Restoration in 1814–1815, political clubs were again formed. The majority

s chose to sit on the right. The "constitutionals" sat in the centre while independents sat on the left. The terms extreme right and extreme left, as well as centre-right and centre-left, came to be used to describe the nuances of ideology of different sections of the assembly. The terms "left" and "right" were not used to refer to

per se, but, strictly speaking, to seating in the legislature. After 1848, the main opposing camps were the " democratic socialists" and the " reactionaries" who used red and white flags to identify their party affiliation. With the establishment of the Third Republic in 1871, the terms were adopted by political parties: the Republican Left, the Centre Right and the Centre Left (1871), the Extreme Left (1876) and the Radical Left (1881). The beliefs of the group called the Radical Left were actually closer to the Centre Left than the beliefs of those called the Extreme Left. Beginning in the early twentieth century, the terms "left" and "right" came to be associated with specific political ideologies and were used to describe citizens' political beliefs, gradually replacing the terms " reds" and "the reaction". The words Left and Right were at first used by their opponents as slurs. Those on the Left often called themselves " republicans", which at the time meant favoring a republic over a monarchy, while those on the Right often called themselves "

" By 1914, the Left half of the legislature in France was composed of Unified Socialists, Republican Socialists and Socialist Radicals, while the parties that were called "Right" now sat on the right side. The use of the words Left and Right spread from France to other countries and came to be applied to a large number of political parties worldwide, which often differed in their political beliefs. There was asymmetry in the use of the terms Left and Right by the opposing sides. The Right mostly denied that the left–right spectrum was meaningful because they saw it as artificial and damaging to unity. However, the Left, seeking to change society, promoted the distinction. As Alain observed in 1931: "When people ask me if the division between parties of the Right and parties of the Left, men of the Right and men of the Left, still makes sense, the first thing that comes to mind is that the person asking the question is certainly not a man of the Left." In British politics, the terms "right" and "left" came into common use for the first time in the late 1930s in debates over the
Spanish Civil War The Spanish Civil War () was a military conflict fought from 1936 to 1939 between the Republican faction (Spanish Civil War), Republicans and the Nationalist faction (Spanish Civil War), Nationalists. Republicans were loyal to the Left-wing p ...
. The Scottish sociologist Robert M. MacIver noted in ''The Web of Government'' (1947):
The right is always the party sector associated with the interests of the upper or dominant classes, the left the sector expressive of the lower economic or social classes, and the centre that of the middle classes. Historically this criterion seems acceptable. The conservative right has defended entrenched prerogatives, privileges and powers; the left has attacked them. The right has been more favorable to the aristocratic position, to the hierarchy of birth or of wealth; the left has fought for the equalization of advantage or of opportunity, for the claims of the less advantaged. Defence and attack have met, under democratic conditions, not in the name of class but in the name of principle; but the opposing principles have broadly corresponded to the interests of the different classes.


Ideological groupings

Generally, the left wing is characterized by an emphasis on "ideas such as

Political parties

Political scientists have made models in which the ideologies of political parties are mapped along a single left–right axis. Klaus von Beyme categorized European parties into nine families, which described most parties. Beyme was able to arrange seven of them from left to right:
communist Communism () is a sociopolitical, philosophical, and economic ideology within the socialist movement, whose goal is the creation of a communist society, a socioeconomic order centered on common ownership of the means of production, di ...

Christian democratic Christian democracy is an ideology inspired by Christian social teaching to respond to the challenges of contemporary society and politics. Christian democracy has drawn mainly from Catholic social teaching and neo-scholasticism, as well ...
, conservative and right-wing extremist. The position of agrarian and regional/ethnic parties varied. A study conducted in the late 1980s on two bases, positions on ownership of the means of production and positions on social issues, confirmed this arrangement. There has been a tendency for party ideologies to persist and values and views that were present at a party's founding have survived. However, they have also adapted for pragmatic reasons, making them appear more similar.

and then support of the Bolshevik Revolution. Right-wing extremist parties are harder to define other than being more right-wing than other parties, but include fascists and some extreme conservative and nationalist parties. Green parties were the most recent of the major party groups to develop. They have mostly rejected socialism and are very liberal on social issues. These categories can be applied to many parties outside of Europe. Ware (1996) asserted that in the United States both major parties were liberal, even though there are left–right policy differences between them.

The right wing believes in the established church both in itself and as an instrument of social cohesion, and they believe in the need for strong political leadership to minimize social and political divisions. To the left, this is seen as a selfish and reactionary opposition to social justice, a wish to impose doctrinaire religion on the population and a tendency to authoritarianism and repression. The differences between left and right have altered over time. The initial cleavage at the time of the French Revolution was between supporters of absolute monarchy (the right) and those who wished to limit the king's authority (the left). During the 19th century, the cleavage was between

Peter Berkowitz writes that in the U.S., the term ''liberal'' "commonly denotes the left wing of the Democratic Party" and has become synonymous with the word ''progressive,'' a fact that is usefully contextualized for non-Americans by Ware's observation that at the turn of the 21st century, both mainstream political parties in the United States, generally speaking, were liberal in the classical sense of the word. Michael Kazin writes that the left is traditionally defined as the social movement or movements "that are dedicated to a radically

have frequently argued that a single left–right axis is too simplistic and insufficient for describing the existing variation in political beliefs and include other axes to compensate for this problem. American libertarian writer David Boaz argued that the political terms ''left'' and ''right'' are used to spin a particular point of view rather than as simple descriptors, with those on the left typically emphasizing their support for working people and accusing the right of supporting the interests of the upper class; and those on the right usually emphasizing their support for

. The open–closed political spectrum has seen increased support following the rise of populist and centrist parties in the 2010s. Norberto Bobbio saw the polarization of the Italian Chamber of Deputies in the 1990s as evidence that the linear left–right axis remained valid. Bobbio thought that the argument that the spectrum had disappeared occurred when either the left or right were weak. The dominant side would claim that its ideology was the only possible one, while the weaker side would minimize its differences. He saw the left and right not in absolute terms, but as relative concepts that would vary over time. In his view, the left–right axis could be applied to any time period. A survey of Canadian legislative caucuses conducted between 1983 and 1994 by Bob Altemeyer showed an 82% correlation between party affiliation and score on a scale for right-wing authoritarianism when comparing right-wing and

caucuses. There was a wide gap between the scores of the two groups, which was filled by liberal caucuses. His survey of American legislative caucuses showed scores by American Republicans and Democrats were similar to the Canadian right and liberals, with a 44% correlation between party affiliation and score. While in many Western European democracies, traditionally the left is associated with socially liberal and economically left values, while the right is traditionally associated with socially conservative and economically right values, Eastern European, post-communist parties are frequently juxtaposed, with economically left parties holding nationalist positions more frequently and economically right parties being liberal and internationalist.
