Libertarianism
Libertarianism can be a kind of centre politics. Many of its beliefs come from classical liberalism. This usually means supporting a capitalist economy but with far more liberal freedoms. This is different from left-wing libertarianism or more right-wing types. But many libertatians do not believe in left vs. right politics. Libertarianism also has roots in anarchism and the Austrian School of economics. Some libertarians are part of the sovereign citizen movement.
