1886: Germanisation policy and Settlement Commission in Polish provinces

Bismarck advocated a tougher policy towards Polish-speaking populations in the Prussian parliament. The Settlement Commission created in 1886 used public funds to encourage land purchases and settlement by German colonists in the eastern provinces, to the detriment of Polish landownership.

1884–1885: Colonial policy reversal — German protectorates and Berlin Conference

No legal proceedings

Having long been reluctant about colonial expansion, Bismarck accepted several African protectorates from 1884 and convened the Berlin Conference on Africa. In February 1885, an imperial letter of protection co-signed by Bismarck placed territories in East Africa under German sovereignty and granted a colonial company jurisdictional powers over local populations.

May–October 1878

1878: Exploits assassination attempts against Wilhelm I and dissolves Reichstag to secure anti-socialist majority

No legal proceedings

Following two assassination attempts against Wilhelm I, Bismarck politically accused the Social Democrats and called new elections after an initial anti-socialist bill failed. Historical sources indicate that he knew attributing the attacks to the SPD was unfounded but exploited the climate of fear to secure election of a more conservative Reichstag.

1871: "Pulpit Law" — criminalisation of certain political statements by clergy

No legal proceedings

At the beginning of the Kulturkampf, the Reich adopted the "Pulpit Law", allowing clergy members to be imprisoned for publicly discussing state affairs in a manner considered likely to disturb public peace. The measure constituted a direct attack on the Catholic clergy's political autonomy.

1870: Deliberately edits Ems Dispatch to provoke France and create a casus belli

No legal proceedings

Bismarck shortened and reformulated the account of a meeting between Wilhelm I and French ambassador Benedetti before releasing it to the press. Authoritative historical sources conclude that he intended to provoke a French reaction and make Prussia appear the victim of aggression.

1863–1866: Governs without parliamentary budget under "gap theory"

No legal proceedings

Unable to reach agreement with the House of Representatives on military reform, Bismarck governed for several years without an approved parliamentary budget, invoking a constitutional "gap" to allow the Crown and government to continue acting.

1862: "Blood and iron" speech during Prussian constitutional crisis

No legal proceedings

Before the budget committee of the Prussian Landtag, Bismarck declared that the great questions of the age would not be decided by speeches and majority votes, but by "iron and blood". The phrase became emblematic of his conception of power and immediately fuelled accusations of militarism and authoritarianism.

II. Documented background

Documented biographical or institutional milestones (elections, appointments, foundings, acquisitions…). These are not controversies and are not counted as such.

  1. March 1885–1886

    1885–1886: Expulsion of approximately 32,000 foreign Poles and Jews from Prussia

    The Prussian government ordered the expulsion of approximately 32,000 Polish and Jewish nationals of Russia or Austria-Hungary living in the eastern provinces. According to the studies cited, approximately one third of those expelled were Jewish. The measure formed part of a policy seeking to limit the Polish presence and strengthen the German character of eastern Prussia.
