The Preußenschlag of 1932 (German pronunciation: [ˈpʁɔʏsənˌʃlaːk], Prussian coup), also known in English as the coup in Prussia or the putsch in Prussia, was the takeover of the Free State of Prussia, the largest German state, by Chancellor Franz von Papen, using an emergency decree issued by President Paul von Hindenburg under Article 48 of the Weimar Constitution on July 20, 1932.
The pretext for this measure was violent unrest in some areas of Prussia and the alleged inability of the Prussian government to handle the matter. The main trigger was the "Altonaer Blutsonntag" ("Altona Bloody Sunday"), a shootout between the SA and Communists in Altona on 17 July 1932, which claimed 18 lives.
It is more likely however that the Prussian government headed by Minister-President Otto Braun, with authority over the powerful Prussian police force, was simply one of the last major forces standing in the way of Papen's plans for nationalist rule.
The move was facilitated by the unstable situation of the Prussian government. The centre-left coalition of the Social Democrats, Centre Party and liberal German Democratic Party had ruled Prussia without interruption since 1918, but had lost its majority in the Landtag (state parliament) in the 1932 elections. However, under the Prussian constitution, a government could be removed from office only if there was a positive majority for a prospective successor. This provision, known as a "constructive vote of no confidence," was intended to ensure that a government had sufficient support to govern.
The Communists and National Socialists held over half the seats between them, but would not cooperate with each other or with other parties. Thus, no politically realistic alternative government was possible, and the Braun-led coalition remained in office.
However, Papen also lacked majority support in the Reichstag. His only means to govern was through the emergency provisions of Article 48, and hence via decrees issued by the Reichspräsident Hindenburg, over whom Papen had great influence. The emergency decree of July 20 dismissed the Braun government and declared Papen Reichskommissar (Reich Commissioner) for Prussia, vested in him all the competences of the Prussian ministries, and gave him direct control over the Prussian government.
The decree was declared partially unconstitutional on October 25, 1932, by the German Constitutional Court, but only in so far as the formal existence of the Prussian cabinet was concerned. The transfer of power to Papen was upheld, while the Braun cabinet retained the right to represent Prussia in the Reichsrat.
Prussia remained under direct administration of the federal government until April 1933. The Enabling Act of 1933 gave Hitler the effective power to enact legislation (including extraconstitutional laws) without the consent of the Reichstag. One of Hitler's first legislative acts was to dissolve all of the state parliaments (except Prussia's) and replace them with legislatures that were constituted based on the results of the partly-free federal election held in March. Prussia was excluded from this measure because it had held state elections at the same time, with a similar result (a Nazi plurality). With the banning of the Communist and Social Democratic parties, the Nazis now had a majority in the Prussian parliament, which elected Hermann Göring as Minister-President. However, under Hitler's rule, German states were effectively replaced by Nazi Gaue, so Göring's post was largely ceremonial.
