Adopting protest tactics and visual performance of the far left, many neo‐Nazis in Europe, particularly in Germany, have developed a new style. Referencing their political opponents, the far‐left Autonomous Movement, they call themselves the Autonomous Nationalists. Though this new style caused intense conflicts in the beginning, Autonomous Nationalists have gained strong influence in the neo‐Nazi movement. What drives neo‐Nazis to adopt tactics such as ‘black blocs’ and certain symbols and dress of their political enemies? Based on movement's documents, semi‐structured interviews and observing demonstrations, this article uses empirical data to identify central dimensions of the Autonomous Nationalist's action repertoire and visual performance and their impact on the neo‐Nazi movement's collective identity. The analysis of external and internal effects reveals that the shift in public appearance strengthened the movement's mobilization potential, but otherwise decreased ideological internalisation and may increase the turnover of activists.
