Firewall against the far-right in Germany

The "Brandmauer" or the “firewall against the far-right" in Germany is a strategy of noncooperation and deplatforming by mainstream political parties and others within German society to suppress the growing influence of far-right politics in Germany, emanating namely from entities such as the AfD and Die Heimat (formerly the National Democratic Party). The primary objective is to buttress the Rechtsstaat, prevent far-right elements from gaining leverage over government policy, and to discourage alignment with or rapprochement toward far-right ideologies within wider German society.
