What happened
Hitler emerged from an internal leadership struggle as the central leader of the National Socialist German Workers' Party, giving the movement a more personalized structure and a clearer mass-political style.
Why it matters
This event matters because Hitler's rise was inseparable from the reshaping of the party around his personal authority, propaganda style, and political instincts. It is the clearest internal starting point for his path to national power.
Notes
Use this as the opening event for Hitler's political ascent rather than his earlier entry into nationalist politics.
