Left-right politics or the Left-right political spectrum is a common way of classifying political positions, political ideologies, or political parties along a one-dimensional political spectrum.

Left vs. Right is an imprecise, broad, dialectical interpretation of a set of factors or determinants. "The Left" and "The Right" are usually understood to represent polar opposites for each determinant, though a particular individual or party may take a "left" stance on one matter and a "right" stance on another.
