Under the Weimar Constitution, the Reich Chancellor was appointed by the Reich President, not automatically given to the leader of the largest Reichstag party. Article 53 states: “The Reich Chancellor ... [is] appointed and dismissed by the Reich President.” Article 54 then says the chancellor needed the confidence of the Reichstag to govern, but that is different from any rule or tradition that the largest party’s leader must become chancellor.

The historical record also contradicts the claim of such a tradition. The German Bundestag’s history of the Weimar Republic notes that the SPD was the strongest political force from 1919 to 1932, yet it “frequently found itself on the opposition benches,” while the Centre Party “provided the majority of the Chancellors.” That means the largest party often did not supply the chancellor.

So the article’s wording is misleading: in Weimar Germany, the presidency appointed the chancellor, and there was no consistent tradition that the leader of the largest Reichstag party was appointed chancellor.

This wording overstates Dachau’s place in the camp system. The United States Holocaust Memorial Museum explains that “the first concentration camps in Germany were established soon after Adolf Hitler's appointment as chancellor in January 1933” and that the SA and police began establishing such camps “beginning in February 1933.” The same source adds that Dachau later became the model that replaced these earlier camps.

USHMM’s Dachau entry is more precise: Dachau was “the first regular concentration camp established by the Nazi government.” In other words, Dachau was not literally the first concentration camp in Germany; it was the first regular/centralized Nazi concentration camp and the model for the later system.

So the article should not call Dachau simply “the first concentration camp in Germany” without qualification.

The 1930 Reichstag election did not give the Nazis and Communists anything close to 40% of the seats.

Authoritative election summaries show that in September 1930 the NSDAP won 107 seats and the KPD won 77 seats, in a Reichstag with 577 seats total. Combined, that is 184 seats out of 577, which is 31.9% of the chamber.

So the article’s “almost 40%” figure is mathematically wrong by about eight percentage points. Even if one looks at vote share instead of seats, the total is still only about 31% (18.3% for the NSDAP plus roughly 13.1% for the KPD).

This sentence misidentifies the man who shot Horst Wessel.

The Deutsches Historisches Museum’s biography of Wessel states that on 14 January 1930 Wessel was shot and badly wounded by “Albrecht Höhler (1898–1933)”, a member of the Roter Frontkämpferbund (RFB). The Deutsche Digitale Bibliothek likewise identifies the criminal proceedings as the “Erster Prozess gegen Ali Höhler ... wegen der Ermordung ... Horst Wessel” and names the accused as Albrecht Höhler.

So the article’s name “Albert Hochter” is incorrect; the historical figure was Albrecht ‘Ali’ Höhler.
