What was the Kulturkampf launched by Otto von Bismarck?

The Kulturkampf (German for "culture struggle") was a period of intense conflict between 1871 and 1887 during which German Chancellor Otto von Bismarck attempted to subject the Roman Catholic Church to state control.1

Driven by his distrust of Catholic loyalty to the newly formed German Empire and concerns over the 1870 proclamation of papal infallibility, Bismarck implemented several restrictive measures:1

• Educational Control: Religious schools were placed under state inspection, and religious teachers were excluded from state schools.1
• Clerical Restrictions: Priests were forbidden from expressing political opinions from the pulpit, and the Jesuit order was dissolved in Germany.1
• Legal Authority: The May Laws of 1873 imposed state oversight on religious training and ecclesiastical appointments, and civil marriage became mandatory in 1875.1

The campaign ultimately failed as Catholics resisted through the Centre Party, leading Bismarck to seek compromise. By 1887, most anti-Catholic legislation was repealed, though the struggle left a legacy of state control over public records and education.1
