Left–right political spectrum

The left–right political spectrum is a system of classifying political positions, ideologies, and parties. Left-wing politics and right-wing politics are often presented as opposed, although a particular individual or group may take a left-wing stance on one matter and a right-wing stance on another, and some stances may overlap and be considered either left- or right-wing depending on the ideology. In France, where the terms originated, the Left has been called "the party of movement" and the Right "the party of order". The intermediate stance is called centrism and a person with such a position is a moderate or centrist.

The spectrum is distinguished by position with regard to a social order present in a particular culture, with the left favoring transformation or dissolution of such structures as part of a general transformation of that culture and the right resisting such transformation, the speed with which it takes place, or advocating rollback of change that has taken place. In Europe, left and right reflect mainly class-issues, with the Left seeking more redistributive policies. In the US, social policies are also important, with the Left promoting social reform and the Right defending conservative Christian values.

The terms "left" and "right" appeared during the French Revolution of 1789 when members of the National Assembly divided into supporters of the king 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." However, the Right opposed the seating arrangement because they believed that deputies should support private or general interests but should not form factions or political parties. The contemporary press occasionally used the terms "left" and "right" to refer to the opposing sides.

When the National Assembly was replaced in 1791 by a Legislative Assembly comprising 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 National Convention 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. However, 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."
