History

The County of Hohenzollern-Sigmaringen was created in 1576, upon the partition of the County of Hohenzollern, a fief of the Holy Roman Empire. When the last count of Hohenzollern, Charles I (1512-1579) died, the territory was to be divided up between his three sons:

• Eitel Frederick IV of Hohenzollern-Hechingen (1545–1605)
• Charles II of Hohenzollern-Sigmaringen (1547–1606)
• Christoph of Hohenzollern-Haigerloch (1552–1592)

The Princes of Hohenzollern-Sigmaringen ruled over a small principality in southwest Germany, with a seat at Sigmaringen Castle. Unlike the Hohenzollerns of Brandenburg and Prussia, the Hohenzollern of Sigmaringen, and their cousins of Hohenzollern-Hechingen, the seniormost branch of the Swabian branch of the House of Hohenzollern, and Hohenzollern of Haigerloch, remained Roman Catholic.

The principality became an independent state in 1815 after the Napoleonic Wars. Its ruler was deposed in the revolutions of 1848. His son, Karl Anton, succeeded him, and turned to Prussia for aid. Prussian troops arrived in August 1849, and in a treaty signed in December Hohenzollern-Sigmaringen was annexed by Prussia, effective in March 1850. The annexation of their state did not, however, mean the end of the importance of the House of Hohenzollern-Sigmaringen.

The last prince, Karl Anton, served as Minister-President of Prussia from 1858-61. Karl Anton's second son, Karl Eitel Friedrich of Hohenzollern-Sigmaringen became prince (1866–1881) and then king (1881–1914) of the Romanians, under the name Carol and the house remained on the throne until the end of the Romanian monarchy in 1947.

Because the Hohenzollern-Hechingen line died out in 1869 with the death of Constantin of Hohenzollern-Hechingen, the head of the House of Hohenzollern-Sigmaringen, Karl Anton of Hohenzollern-Sigmaringen, took the title of prince (Fürst) of Hohenzollern instead of Hohenzollern-Sigmaringen.

French opposition to the candidacy of Carol's elder brother Prince Leopold for the throne of Spain triggered the Franco-Prussian War (1870–1871), which led to the founding of the German Empire in January 1871.
