House of Hohenzollern - Swabian Senior Branch

Swabian Senior Branch

The senior Swabian branch of the House of Hohenzollern was founded by Frederick II, Burgrave of Nuremberg.

Ruling the minor German principalities of Hechingen, Sigmaringen and Haigerloch, this branch of the family decided to remain Roman Catholic and from 1567 onwards split into the Hohenzollern-Hechingen, Hohenzollern-Sigmaringen and Hohenzollern-Haigerloch branches. Romanian branch of this family became Orthodox, starting from Ferdinand's I children. When the last count of Hohenzollern, Charles I of Hohenzollern (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)
• Christopher of Hohenzollern-Haigerloch (1552–1592)

They never expanded from these three Swabian principalities, which was one of the reasons they became relatively unimportant in German history for much of their existence. However, they kept royal lineage and married members of the great royal European houses.

In 1767 the principality of Hohenzollern-Haigerloch was incorporated into the other two principalities. In 1850, the princes of both Hohenzollern-Hechingen and Hohenzollern-Sigmaringen abdicated their thrones, and their principalities were incorporated as the Prussian province of Hohenzollern.

The last ruling Prince of Hohenzollern-Sigmaringen, Karl Anton, would later serve as Minister-President of Prussia between 1858 and 1862.

The Hohenzollern-Hechingen finally became extinct in 1869. A descendent of this branch was Sophie Chotek, wife of Archduke Francis Ferdinand of Austria-Este.

However, a member of the Hohenzollern-Sigmaringen family, Charles Eitel, second son of prince Karl Anton, was chosen to become prince of Romania as Charles I in 1866. In 1881 Charles I became the first king of the Romanians.

Charles' older brother, Leopold, was offered the Spanish throne after a revolt removed queen Isabella II in 1870. Although encouraged by Bismarck to accept it, Leopold backed down once France's Emperor, Napoleon III, stated his objection. Despite this, France still declared war, beginning the Franco-Prussian war.

Charles I had only a daughter who died very young, so Leopold's younger son Ferdinand I would succeed his uncle as king of the Romanians in 1914, and his descendants continued to rule in Romania until the end of the monarchy in 1947.

In modern times this branch has been represented only by the last king, Michael I of Romania, and his daughters. The descendants of Leopold's oldest son William continue to use the titles of prince or princess of Hohenzollern.

King Michael renounced his connection in 2011.
