AfD gains and Germany's firewall: what happens after winning votes

Alternative for Germany has converted anger over migration, prices, energy and political distrust into durable electoral strength, particularly in eastern Germany. Its latest regional gains deepen the pressure on Chancellor Friedrich Merz's Christian Democrats and raise a question that vote share alone cannot answer: who will govern with it?

Germany's established parties maintain a non-cooperation principle commonly called the Brandmauer, or firewall. It is a political commitment rather than a constitutional rule. Where AfD finishes first but lacks a majority, other parties can still construct a government without it. That preserves the barrier while often producing broader and less comfortable coalitions.

The party's classification also requires precision. News organisations commonly describe AfD as far right; Germany's domestic-intelligence authorities have subjected parts of the movement to scrutiny, with classifications contested through the courts. Those legal processes should not be collapsed into campaign rhetoric or treated as substitutes for evidence about individual voters.

The next phase is institutional. AfD will argue that exclusion disregards its voters; opponents will argue that democratic parties are entitled to refuse cooperation. The measurable questions are coalition arithmetic, parliamentary behaviour and whether mainstream parties can answer the grievances on which AfD has grown without adopting its most radical positions.
