The Kapp Putsch of 1920

The precise allegation

Right-wing military officers and Freikorps units attempted to overthrow Germany's Weimar government in March 1920. The coup conspiracy was overt and documented; the government fled Berlin, and a general strike helped defeat the putsch. The unresolved issue is not whether the coup occurred, but how much support it had among military elites who refused to defend the republic.

Chronology and political context

Wolfgang Kapp and General Walther von Lüttwitz led the coup after the government ordered the dissolution of Freikorps formations. Reichswehr units declined to fire on the rebels, prompting elected leaders to leave Berlin. Workers' organizations called a general strike that paralyzed the country. The putsch collapsed after several days, though political violence continued.

Primary historical record

Government proclamations, military orders, press accounts, and court proceedings document the attempted seizure. The record shows collaboration among military and civilian figures, as well as the official army's refusal to suppress it. Subsequent prosecutions were lenient and incomplete, limiting precise assignment of responsibility across the officer corps.

Corroboration and contrary evidence

Historical scholarship on the Weimar Republic confirms the role of Freikorps and conservative elites. The general strike's effectiveness is independently documented through administrative paralysis and contemporary reporting. Some officials later portrayed the army's neutrality as unavoidable; historians regard it as a revealing institutional choice rather than a neutral absence of action.

What remains uncertain

The number of officers who privately supported the coup, the degree of coordination outside Berlin, and the putschists' prospects of lasting control remain difficult to quantify. Later political accounts had incentives to excuse or magnify involvement. The coup's failure does not mean its consequences were minor: it exposed the republic's weak control over armed forces.

Calibrated verdict

A right-wing coup attempt is historically established, and military nonintervention materially enabled its initial success. The strike helped restore constitutional government. The event supports a claim of an attempted anti-democratic conspiracy, but not every conservative official can be labeled a participant without individualized evidence.

What evidence could change this assessment

Complete military correspondence from March 1920 or independently corroborated records of prior coordination could establish how widely the putsch was planned. Records identifying officers who actively resisted or assisted the coup would refine culpability. Such evidence would sharpen institutional responsibility without changing the established fact of the attempted overthrow.
