WThe Holy Roman Empire was a multi-ethnic complex of territories in Western and Central Europe that developed during the Early Middle Ages and continued until its dissolution in 1806 during the Napoleonic Wars. The largest territory of the empire after 962 was the Kingdom of Germany, though it also included the neighboring Kingdom of Bohemia and Kingdom of Italy, plus numerous other territories, and soon after the Kingdom of Burgundy was added. However, while by the 15th century the Empire was still in theory composed of three major blocks – Italy, Germany, and Burgundy – in practice only the Kingdom of Germany remained, with the Burgundian territories lost to France and the Italian territories, ignored in the Imperial Reform, mostly either ruled directly by the Habsburg emperors or subject to competing foreign influence. The external borders of the Empire did not change noticeably from the Peace of Westphalia – which acknowledged the exclusion of Switzerland and the Northern Netherlands, and the French protectorate over Alsace – to the dissolution of the Empire. By then, it largely contained only German-speaking territories, plus the Kingdom of Bohemia. At the conclusion of the Napoleonic Wars in 1815, most of the Holy Roman Empire was included in the German Confederation.
WThe Archbishopric of Magdeburg was a Roman Catholic archdiocese (969–1552) and Prince-Archbishopric (1180–1680) of the Holy Roman Empire centered on the city of Magdeburg on the Elbe River.
WThe March or Margraviate of Lusatia was as an eastern border march of the Holy Roman Empire in the lands settled by Polabian Slavs. It arose in 965 in the course of the partition of the vast Marca Geronis. Ruled by several Saxon margravial dynasties, among them the House of Wettin, the lordship was contested by the Polish kings as well as by the Ascanian margraves of Brandenburg. The remaining territory was finally incorporated into the Lands of the Bohemian Crown in 1367.
WThe March of Merseburg was a short-lived march of the Holy Roman Empire. It comprised the lands of the Polabian Slavs beyond the margravial residence at Merseburg on the Saale river.
WThe March of Zeitz was a march of the Holy Roman Empire. It was created by Emperor Otto I in the division of the marca Geronis in 965, following the death of Gero the Great. Its capital was Zeitz. Its first and only margrave was Wigger. In 982, Zeitz was reunited with the marches of Meissen and Merseburg under Ricdag, who thus temporarily reunited all of the southern marca Geronis save the Saxon Ostmark. In 983, Zeitz was overrun by the Sorbs and the marcher territory fell into the hands of the Slavs. Nevertheless, the march of Zeitz, along with the later March of Lusatia, was a recurring division of the Meissen march during the reign of the Emperor Henry II.
WThe Margravate of Meissen was a medieval principality in the area of the modern German state of Saxony. It originally was a frontier march of the Holy Roman Empire, created out of the vast Marca Geronis in 965. Under the rule of the Wettin dynasty, the margravate finally merged with the former Duchy of Saxe-Wittenberg into the Saxon Electorate by 1423.
WThe Northern March or North March was created out of the division of the vast Marca Geronis in 965. It initially comprised the northern third of the Marca and was part of the territorial organisation of areas conquered from the Wends. A Lutician rebellion in 983 reversed German control over the region until the establishment of the March of Brandenburg by Albert the Bear in the 12th century.
WThe Saxon Eastern March was a march of the Holy Roman Empire from the 10th until the 12th century. The term "eastern march" stems from the Latin term marchia Orientalis and originally could refer to either a march created on the eastern frontier of the East Frankish duchy of Saxony or another on the eastern border of the Duchy of Bavaria: the Bavarian marchia Orientalis, corresponding to later Austria.
