Far-right politics, or right-wing extremism, is a spectrum of political thought that tends to be radically conservative, ultra-nationalist, and authoritarian, often also including nativist tendencies. The name derives from the left–right political spectrum, with the "far right" considered further from center than the standard political right.

The left–right political spectrum is a system of classifying political positions, ideologies and parties, with emphasis placed upon issues of social equality and social hierarchy. In addition to positions on the left and on the right, there are centrist and moderate positions, which are not strongly aligned with either end of the spectrum. It originated during the French Revolution based on the seating in the French National Assembly.
