Wilhelm I, German Emperor

Born in Berlin on 22 March 1797, Wilhelm was the second son of Frederick William III and Queen Luise. He entered military service young, fought against Napoleon in 1814 and held successive commands. The accession of his childless elder brother Frederick William IV made him heir to the throne.

During the Berlin revolution of 1848, his support for military suppression provoked intense opposition and a temporary departure for Britain. He commanded forces against the Baden and Palatinate uprisings in 1849. Later residence in Koblenz brought more contact with liberals without displacing his commitment to royal and military authority.

After his brother fell ill, Wilhelm became regent, formally assuming that role in 1858. He swore to uphold the Prussian constitution and appointed a more liberal ministry. As king from 1861, however, he confronted parliament over the financing of military reform.

In September 1862 he appointed Bismarck, supporting military policy without the required parliamentary budget approval. Their durable partnership did not represent a united royal household: Queen Augusta and the crown-princely couple strongly distrusted Bismarck. Military organization had become a dispute over constitutional authority.

Wars in 1864, 1866 and 1870–1871 established Prussian predominance. Proclaimed German emperor at Versailles on 18 January 1871, Wilhelm retained the Prussian crown. The April constitution vested the federal presidency in Prussia’s king and assigned the emperor international representation, parliamentary convocation and appointment of the chancellor.

He generally supported Bismarck but could pursue different preferences. In 1879 he traveled to Russia seeking reconciliation with Alexander II after the Berlin Congress, while hesitating over closer alliance with Austria-Hungary. Dynastic ties and strategic policy could diverge. He died in Berlin on 9 March 1888 and was succeeded by Frederick III.
