The Marca Geronis or March of Gero [1] was a vast super-march in the middle of the tenth century. It was probably created for Thietmar in the 920s and passed consecutively to his two sons, Siegfried and Gero. On Gero's death in 965 it was divided into five different marches: the Nordmark, Ostmark, Meissen, Zeitz, and Merseburg.
Because Siegfried's and Gero's comital seat was Merseburg, it has sometimes been called the March of Merseburg. However, there is also a Merseburger march which grew out of it after 965. Because the central diocese in his march was Magdeburg, it is sometimes called the March of Magdeburg. Other historians prefer to call it the Saxon Eastern March or Ostmark, but these terms are also applied to another march which grew out of it in 965. Because the Marca Geronis was created simultaneously with the March of Billung to the north, it is sometimes said to be the southern half of the Ostmark. Some historians even call it the "March of Meissen." [2] Within the span of one page, James Westfall Thompson refers to it as both the "Sorben Mark" and the "Thuringian March". [3]
Part of the complication involved in ascertaining the territoriality of the march over which Gero ruled is the nature of the margravial title in tenth-century Saxony. It may have signified territorial governance, but on the other hand may have been an honorific for especially powerful counts signifying nothing more than a preeminence in providing defence of the provinces in which were found their counties. It has been suggested that marcher jurisdictions even overlapped within provinces.
In 965, Merseburg became the centre of a smaller, more restricted march belonging to Gunther. On Gunther's death in 982, it was united to the March of Meissen.
The Altmark is a historic region in Germany, comprising the northern third of Saxony-Anhalt. As the initial territory of the March of Brandenburg, it is sometimes referred to as the "Cradle of Prussia", as by Otto von Bismarck, a native of Schönhausen near Stendal.
The 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.
Gero I, sometimes called the Great, was a German nobleman who ruled an initially modest march centred on Merseburg in the south of the present German state of Saxony-Anhalt, which he expanded into a vast territory named after him: the marca Geronis. During the mid-10th century, he was the leader of the Saxon Ostsiedlung.
The Margravate or Margraviate 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.
Rikdag, also called Ricdag, Riddag, or Rihdag, was Margrave of Meissen from 979 until his death. In 982, he also acquired the marches of Merseburg and Zeitz. After the Great Slav Rising in 983, he temporarily reunited all of the southern marca Geronis under his command. His march included the territory of the Chutizi and Dolomici tribes.
The 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.
The 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.
The 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.
Dietrichof Haldensleben was a count in the Schwabengau, later also in the Nordthüringgau and the Derlingau, who was the first Margrave of the Northern March from 965 until the Great Slav Rising of 983. He also bore the title of a dux (duke) in contemporary sources.He was a ancestor of John V
The March or Margraviate of Lusatia was 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.
OdoI was margrave in the Saxon Eastern March of the Holy Roman Empire from 965 until his death.
Gunther was the Margrave of Merseburg from 965 until his death, upon which the march of Merseburg was united to that of Meissen.
The Sorbian March was a frontier district on the eastern border of East Francia in the 9th through 11th centuries. It was composed of several counties bordering the Sorbs. The Sorbian March seems to have comprised the eastern part of Thuringia.
The Billung March or March of the Billungs was a frontier region of the far northeastern Duchy of Saxony in the 10th century. It was named after the family which held it, the House of Billung.
Thietmar (II) (c. 945 – 3 August 979) was Margrave of Meissen from about 976 until his death.
Thietmar (I) (also Thiatmar, Dietmar, or Thiommar) (died 1 June 932), Count and Margrave, was the military tutor (vir disciplinae militaris peritissmus) of Henry the Fowler while he was the heir and then duke of the Duchy of Saxony. He probably kept a small body of elite retainers (though he once feigned at having thirty legions behind him) armed with the latest in military technology and well-supplied with expensive horses. His armored cavalry played a decisive role in winning the Battle of Lenzen on 4 September 929, securing German domination along the Elbe river against West Slavic peoples.
Wiprechtof Groitzsch was the Margrave of Meissen and the Saxon Ostmark from 1123 until his death. He was born to a noble family of the Altmark, the son of Wiprecht of Balsamgau and Sigena of Leinungen. After his father's death in 1060, he was raised at the court of Lothair Udo II, Margrave of the Nordmark, in Stade.
The Nordthüringgau was a medieval county in the Eastphalian region of the German stem duchy of Saxony.
In the Slavic revolt of 983, Polabian Slavs, Wends, Lutici and Obotrite tribes, that lived east of the Elbe River in modern north-east Germany overthrew an assumed Ottonian rule over the Slavic lands and rejected Christianization under Emperor Otto I.
