The Duchy of Franconia (German: Herzogtum Franken) was one of the five stem duchies of East Francia and the medieval German kingdom emerging in the early 10th century. The word Franconia, first used in a Latin charter of 1053, was applied like the words Francia, France, and Franken, to a portion of the land occupied by the Franks.[1]


It stretched along the valley of the River Main from its confluence with the Upper Rhine up to the Bavarian March of the Nordgau, in the areas of the present-day Bavarian region of Franconia, the adjacent southern parts of the Free State of Thuringia, northern Baden-Württemberg (i.e. Rhine-Neckar and Heilbronn-Franken) and Hesse. It also included several Gaue on the left bank of the Rhine around the cities of Mainz, Speyer and Worms comprising present-day Rhenish Hesse and the Palatinate region.

Located in the centre of what was to become the German kingdom about 919, it bordered the stem Duchy of Saxony in the north, Austrasian Lorraine (Upper and Lower Lorraine) in the west, the Duchy of Swabia in the southwest and the Duchy of Bavaria in the southeast.


The territory of the Duchy of Franconia was the part of the core Frankish realm of Austrasia that was not included into Lotharingia by the Treaty of Verdun

The duchy evolved during the decline of the Carolingian Empire, when it was a part of the core Frankish realm of Austrasia (i.e. "Eastern Francia"), and got its form when the northwestern parts of Austrasia became a new realm called Lotharingia.

Unlike the other stem duchies, Franconia did not evolve into a stable political entity, though the local Salian counts held large estates in the western parts (Rhenish Franconia). In 906 the Conradine relative Count Conrad the Younger in the Lahngau is mentioned as a dux Franconiae. Upon the extinction of the East Frankish Carolingians in 911, he was elected the first German king (as Conrad I, Rex Francorum according to Salic law) and was succeeded as Franconian duke by his younger brother Eberhard. However, the Conradines did not prevail against the rising Saxon Ottonians: In 919 Duke Henry of Saxony succeeded Conrad as German king and the Franconian stem duchy was seized by Henry's son King Otto I of Germany after an unsuccessful revolt of Duke Eberhard was shattered at the 939 Battle of Andernach. King Otto did not appoint a new duke of Franconia, and the duchy was fragmented into several counties and bishoprics, which reported to the German kings directly.

The Salian counts in Rhenish Franconia were sometimes mentioned as Franconian dukes and they became Germany's royal and imperial dynasty in 1024. In 1093 their Franconian territories were granted as a fief to the palatine count of Aachen, which would evolve into the important German principality of Electoral Palatinate (Kurpfalz). With the advancement of Count Conrad the Red, Rhenish Franconia became the heartland of the Salian dynasty, which provided four emperors in the 11th and 12th centuries: Conrad II, Henry III, Henry IV, and Henry V. It contained the cities of Mainz, Speyer and Worms, the latter two being the administrative centres of countships within the hands of the Salian descendants of Conrad the Red. These counts were sometimes referred to as the Dukes of Franconia.

Emperor Conrad II was last to bear the ducal title. When he died in 1039, Rhenish Franconia was governed as a constellation of small states, like the cities of Frankfurt, Speyer and Worms, the Prince-bishoprics of Mainz, Speyer, and Worms, as well as the Landgraviate of Hesse, then part of Thuringia. Alongside these powerful entities were many smaller, petty states. In 1093, Emperor Henry IV gave the Salian territories in Rhenish Franconia as a fief to Henry of Laach, the Count palatine of Lower Lorraine at Aachen. His lands would evolve into the important principality of Electoral Palatinate. While Emperor Frederick Barbarossa in 1168 granted the ducal title to the Prince-Bishops of Würzburg in Eastern Franconia, Rhenish Franconia was divided and extinguished. Its territories became part of the Imperial Upper Rhenish Circle in 1500.


The ducal title was held by the German kings and Holy Roman Emperors until the death of Emperor Conrad II in 1039. It was later claimed by the Prince-Bishops of Würzburg. Though in 1116 the Salian emperor Henry V once again vested Conrad of Hohenstaufen with the ducal dignity, Conrad's nephew Emperor Frederick Barbarossa finally received the rights from the Würzburg bishops in 1168. The bishops however continued to pretend their claim to the duchy until the bishopric was secularized in 1803 and absorbed into the Electorate of Bavaria. When the Grand Duchy of Würzburg, the Archbishopric of Mainz and most other parts of Franconia became part of the Kingdom of Bavaria in 1814, the kings assumed the ducal title. The present head of the House of Wittelsbach, Franz, Duke of Bavaria (* 1933) is still traditionally styled as His Royal Highness the Duke of Bavaria, Duke in Swabia and Franconia, Count Palatine of the Rhine.
