March of the Nordgau
The March of the Nordgau (German: Markgrafschaft Nordgau) or Bavarian Nordgau (Bayerischer Nordgau) was a medieval administrative unit (Gau) on the frontier of the German stem duchy of Bavaria. It comprised the region north of the Danube and Regensburg (Ratisbon), roughly covered by the modern Upper Palatinate stretching up to the river Main and, especially after 1061, into the Egerland on the border with Bohemia.
The area east of Franconia proper up to the Bohemian Forest had been settled by Germanic Varisci and Armalausi tribes in ancient times; after the Migration Period it was occupied by the Merovingian king Chlodio. From the mid 6th century onwards, the region was Christianised by several wandering bishops, among them Saints Boniface and Emmeram of Regensburg. In 739, the Diocese of Regensburg was founded. The great fortress of Wogastisburg was built at the insistence of Saint Boniface by Charles Martel.
When King Charlemagne deposed Duke Tassilo III of Bavaria in 788, he entered the Nordgau and brought the Carolingian Empire into contact with Bohemia permanently. For this reason, the incorporated Nordgau has been called the Bohemian March on occasion, although this term is also reserved for the later Margraviate of Moravia. By a 806 deed issued at Thionville, Charlemagne separated the Bavarian lands left of the Danube including the ducal residences of Regensburg and Lauterhofen, called pagum, qui dicitur Northgowe. His chancellor Einhard reached the confirmation by Pope Leo III.
The Nordgau was again separated from Bavaria following the death of the Luitpolding duke Arnulf in 937. There has been some confusion over whether or not the Nordgau was separated from Bavaria at this date or only as late as 976, when the East Franconain count Berthold of Schweinfurt, who had helped to suppress the rebellion of the Bavarian duke Henry the Wrangler against Emperor Otto II, was appointed margrave to administrate the region as a distinct march.
Likewise, Berthold's son Count Henry of Schweinfurt appeared as Margrave of the Nordgau in 994. He backed the election of Duke Henry IV of Bavaria as King of the Romans in 1002, however, he the new king (Henry II) responded with ingratitude. Count Henry soon after joined a revolt (Schweinfurter Fehde) led by the Polish ruler Bolesław I the Brave, after which he was deposed and arrested. In 1004, King Henry II installed his brother-in-law Count Henry of Luxembourg as Bavarian duke and gave the temporal authority of the Nordgau region over to the Bishopric of Bamberg, which he heavily favoured throughout his career. However, the margravial title survived in a succession of families in the region. Count Henry's possessions were partly restored and his descendants used the title "Margrave of Schweinfurt".
Throughout the 11th and 12th centuries, the Nordgau was a pathway for invading armies from Bohemia and Hungary and for the countering armies of the Holy Roman Empire. In the mid 11th century, the Salian emperor Henry III had an Imperial castle erected at Cham to encounter the forces of Duke Bretislaus I of Bohemia. It became the residence of the Rapotonen noble family, who eventually received the margravial title by royal grant about 1073, passing it down as "Margrave of Vohburg" to their descendants.
Margrave Diepold III (d. 1146) was a loyal supporter of Emperor Henry V and founder of the abbeys in Reichenbach and Waldsassen. From about 1125, he had the fortress of Eger (Cheb) erected at the border with Bohemia. His daughter Adelaide married the Swabian duke and later emperor Frederick Barbarossa in 1147.
The Egerland was incorporated as a Hohenstaufen imperial territory upon Diepold's death and the town of Eger itself was inherited by Emperor Frederick Barbarossa in 1167. It attained the immediate status of an Imperial city, while large parts of the Norgau were controlled by the Bavarian House of Wittelsbach from the mid 13th century onwards. In 1322 the Wittelsbach emperor Louis IV gave the Egerland in pawn to the Kingdom of Bohemia. By the 1329 Treaty of Pavia, he ceded the remaining Nordgau region to his Palatinate nephews Rudolf II and Rupert I, whereafter it became known as the "Upper Palatinate".
