Germany's 'Brandmauer': A political firewall designed to isolate the far-right

History · Published 19 October 2026 Swipe more like this →

In short: In German politics, the 'Brandmauer' is more than a metaphor; it is a deliberate strategy of noncooperation. By creating a barrier between mainstream parties and the far-right, the establishment seeks to prevent the normalization of anti-democratic discourse. But as the line between policy and ideology blurs, the firewall faces its toughest test.

The 'Brandmauer' (firewall) is a strategy of demarcation used by mainstream German political parties to suppress the influence of far-right groups like the Alternative for Germany (AfD). The goal is to prevent these parties from gaining legitimacy or access to government power. This policy is widely supported across Germany but faces criticism for being potentially undemocratic. Some argue that by refusing to engage, mainstream parties allow the far-right to claim victimhood or skirt responsibility for their own actions.

The effectiveness of this firewall is currently under intense scrutiny. While the CDU officially maintains a stance of incompatibility with the AfD since 2018, research suggests the barrier is porous. A 2024 study by the Rosa Luxemburg Foundation identified 121 instances of cooperation between democratic and far-right parties in former Eastern German states between 2019 and 2023. Notably, the CDU had the highest number of collaborations, often by supporting AfD motions on non-controversial topics like transport, sport, and culture.

A significant turning point occurred in January 2025, when a resolution on immigration and border crossings passed with a razor-thin margin of 348 to 345 votes. This required the AfD to play a decisive role, leading some media outlets to report that the firewall had 'cracked.' Furthermore, research indicates that when mainstream politicians adopt far-right themes—such as restrictive immigration—it can inadvertently legitimize those views and erode social norms of tolerance, even if the intent is to address public concerns.

At the local level, the firewall manifests as specific 'non-cooperation' rules: no joint proposals, no shared press conferences, and no joint statements with right-wing factions. However, these measures face legal and practical hurdles. In 2025, a Dortmund council attempted to formalize a motion requiring decisions to be approved only by non-AfD councillors, but the move was declared illegal by a neighboring administration, which argued it would create 'second-class' representatives.
