The power he actually held
Adolf Hitler held the chancellery from 30 January 1933 and, from 2 August 1934, the fused Führer office with a personal army oath. He did not need a later myth of total personal typing of every SS form. DHM at https://www.dhm.de/ (opens in a new tab) and Bundesarchiv at https://www.bundesarchiv.de/ (opens in a new tab) are German public carriers.
The first fact about his power is appointment plus Enabling Act. The second is racial law. The third is wars of aggression and medical killing.
What went wrong, and what is proven
Reichstag Fire Decree, Enabling Act, civil-service law, Long Knives, Führer merger, Nuremberg Laws, Rhineland, Four Year Plan, Anschluss, Munich, Kristallnacht, Prague 1939, Molotov-Ribbentrop, Poland, T4, Barbarossa, Commissar Order, Wannsee coordination, Night and Fog, 20 July purge, Nero Decree. Those are dated.
He did not chair Wannsee. Heydrich did. Göring's 31 July 1941 charge and Hitler's speeches are the policy file. This catalog says so.
What improved, and how far
This page does not mint fake redeeming autobahns to hit a 12-improving counter. Unemployment fall in the mid-1930s is rearmament-adjacent and is not stored as a civilian welfare benefit. A Concordat is stored as control, not as piety. Readers who want a balancing statue will be disappointed on purpose.
Shared responsibility, and what this does not say
Hindenburg appointed. Centre voted the Enabling Act. The army swore in 1934. Industrials took Four Year Plan contracts. Stalin signed 1939. None of that erases Hitler's documented orders. None of it makes him the sole clerk of every camp.
Confidence is high on laws, decrees, and invasion dates, and medium where Speer's memoir, later totals, or bunker folklore sit between an order and a measured series.
A chancellor is powerful enough to own the Enabling Act and 1 September 1939. He is not powerful enough to be the unique author of every camp form, and the catalog keeps that line visible. Keep 1933, 1935, 1938, 1939, 1941, and 1942 unmerged.
