can somebody tell me how the name left and right was first u

"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."  copyright ybarra-cgm

The interesting thing about placing the preferred people on the King's Right Hand Side is that the king (and those "preferred people") lost shortly afterwards and the king was deprived of his noggin. Maybe if he'd switched them, he'd have survived?
