Central Europe





During the general collapse of East Francia, or Germany, in the twelfth century, Swabia's dissolution left the way clear for its main successors to emerge from the shadows. Württemberg and Baden grew to encompass most of Swabia's former territory.

The collapse of Swabia was effectively triggered by the death of Holy Roman Emperor Henry V. Duke Frederick II of Swabia put himself forward as a candidate for the imperial title but was defeated by the successful election of Lothar II. Conflict erupted between the two, and the rivalry had a destabilising effect on Germany as a whole and Swabia in particular. In 1137 the county of Württemberg was formed in western central Swabia as another step towards the total disintegration of the duchy during the general political crisis, although it took a further century to complete the process.

With the death of John Parricide, any claim to the former Swabian duchy dies with him. Large areas of its territory have already gone to the established county of Württemberg and the margraviate of Baden. Territory formerly belonging to the Alemanni people also later forms parts of Austria (Vorarlberg), France (Alsace) and Switzerland, as well as the Bavarian Swabia region of Bavaria.

Map Kingdom of Württemberg

The duchy was elevated to a kingdom by France's Napoleon Bonaparte when it joined his Confederation of the Rhine. Thanks to the marriage between Frederick and Duchess Augusta of Brunswick-Wolfenbüttel in 1780, their children, including the future William I, were direct descendants of King George II of Great Britain and Hanover.

William I

Son of Frederick.


The younger brother of William I is Prince Paul of Württemberg. Prior to his marriage in 1805, Paul has a mistress named Friederike Porth by whom he fathers an illegitimate daughter named Karolina von Rothenburg (born 1805, shortly after her father's marriage). Despite his marriage, the child grows up around her father and finds a supportive and loving uncle in William I.

In 1836, Karolina falls pregnant by Karl, Baron (Freiherr) von Pfeffel of Bavaria. Paul is the one to make arrangements behind the scenes to ensure that his daughter receives a wedding which takes place before important dignitaries in the private chapel of the Bishop's Palace in Augsburg. The great-great-great-grandson of this union is Boris Johnson, mayor of London (2008-2012). This also makes him a direct (if illegitimate) descendant of George II of Great Britain and Hanover (as backed up by the BBC television series, Who Do You Think You Are).

1864 - 1891



Württemberg becomes a sub-kingdom in Prussia's German empire.

1891 - 1918

William II

Died 1921.


Wilhelm of Urach, a member of the royal house, is briefly elected king of Lithuania in the hope that this will bring about a form of independence. Instead, Germany's collapse in 1918 brings about the creation of a republic. Worse still for Württemberg, all German monarchies are abolished upon the defeat of the German empire at the end of the First World War. Württemberg becomes a constituent part of the new federal Germany and its future fortunes would be tied to this new political creation.
