One must not only THINK. One must also LEARN.
"...The terms Left and Right have been used to refer to political affiliation since the early part of the French Revolutionary era. They originally referred to the seating arrangements in the various legislative bodies of France, specifically in the French Legislative Assembly of 1791, when the king was still the formal head of state, and the moderate royalist Feuillants sat on the right side of the chamber, while the radical Montagnards sat on the left.[9] This traditional seating arrangement continues to be observed by the Senate and National Assembly of the French Fifth Republic.
Originally, the defining point on the ideological spectrum were the attitudes towards the ancien régime ("old order"). "The Right" thus implied support for aristocratic, royal and clerical interests, while "The Left" implied support for republicanism, secularism and civil liberties.[1] At that time, support for socialism and liberalism were regarded as being on the left. The earlier "left-wing" politicians were advocates of laissez faire capitalism[citation needed] and the "right-wing" politicians opposed it, until the early nineteenth century when anti-capitalism gained favour among the leftists due to the rise of socialism.
However, among the left-wing were not only liberals but also Robespierre, who was a protosocialist, a disciple of Rousseau. When his section of the Jacobin party got the power, left-controlled French National Convention moved to decree numerous economic interventions during the Revolution, including price controls (enforced under penalty of death),[10] forced loans on those with incomes exceeding 1000 livres, and the abolishment of the Paris Stock Exchange and all joint-stock companies.[11]
During the French Revolution, the definition of who was on the left and who on the right shifted greatly within only a few years. Initially, leaders of the Constituent Assembly like Antoine Barnave and Alexandre de Lameth, who supported a very limited monarchy and a unicameral legislature, were seen as being on the left, in opposition to more conservative leaders who hoped for a more British-style constitutional monarchy (the British monarch was a very powerful figure in 18th century British politics, unlike today), and to those who opposed the revolution outright. By the time of the convening of the Legislative Assembly in 1791, their party, now called the Feuillants, had come to be seen as on the right due to its support for any form of monarchy, and for the limited franchise of the 1791 Constitution. By the time of the National Convention only a year later, the semi-liberal Girondins, who had been on the left in the Legislative Assembly due to their support for external war to spread the revolution, and strong dislike for the king, had themselves come to be seen as being on the right due to their ambivalence about the overthrow of the monarchy, their opposition to Louis's execution, and their dislike for the city of Paris, which had come to see itself as the heart of the Revolution.
It should be emphasized that in these years there was little in their views of economic policy to distinguish the various factions of the French Revolution from one another. Both Montagnards on the (1792-1793) left and Monarchiens on the (1789) right were essentially orthodox liberals on economic matters, although the Montagnards proved more willing than other groups to court popular favor in Paris by agreeing to (temporary) economic controls in 1793, and there were indeed economic radicals to the left of the Montagnards who insisted on genuine economic redistribution to achieve the Egalité promised by the revolutionary slogan.
Instead, the focus of ideological differences during the revolution had much more to do with attitudes towards the Revolution itself - whether it was a horror against God and Nature to be turned back and destroyed, a necessary rupture with the past that must (at some point) be brought to a close so order and good government could be restored, or a necessary and permanent feature of French political life. For the most part, nearly all of the political figures of the Revolution itself held the middle position, and disagreed largely on at what point it was time to call the Revolution fulfilled.
After the revolution settled down in 1794 following the fall of Robespierre on 9 Thermidor, a more clear-cut political spectrum began to emerge. On the left were Jacobins, former supporters of Robespierre and the Terror, who longed to see the restoration of the democratic Constitution of 1793. The most prominent of these was Babeuf, now considered a proto-communist. On the right were the monarchists, who hoped to restore a monarchy, whether constitutional or absolute. In the center were the Thermidorians, who wrote the Constitution of 1795 and hoped that the limited republic of the Directory would stand in the middle position between these two extremes. The failure of the Directory did little to change these basic political alignments - Jacobins and Monarchists remained, and most of those who had initially supported the Directory came to support the dictatorship, and eventually the rule, as emperor, of Napoleon Bonaparte.
It was during this period of retrenchment in France itself that the idea of the left-right political spectrum began to be exported to the rest of Europe. As the French conquered and annexed lands beyond the French border, it was again the issue of attitudes towards the French Revolution, which largely determined political alignment. With the rise of Napoleon, though, matters became more complicated, as those outside France who had supported the Revolution were forced to decide whether this also meant supporting Napoleon's dictatorship. At the same time, the traditional rulers of the other states of Europe - whether Napoleon's enemies in Austria and Prussia, or dependent rulers in German states like Bavaria, often came to a nuanced position on Napoleon and the Revolution's legacy, hoping to import many of the centralizing reforms which had brought the old regime to an end and allowed, it seemed, Napoleon's great victories, without opening the way for the chaos and violence of the Terror.
