The political philosophy of leaning o the right or left dates back to what event?

The political philosophy of leaning right or left dates back to the seating arrangements in the French National Assembly during the late 18th century, particularly around the time of the French Revolution. Those who supported the monarchy and traditional institutions sat on the right, while those advocating for revolutionary change and egalitarianism sat on the left. This spatial division has since evolved into broader ideological distinctions between conservative (right) and progressive (left) political beliefs.
