William I (died 16 April 963) is the first known member of the house of the Counts of Weimar.
William was first mentioned in a 949 deed as a count ( Graf ) in Thuringia. [1] Originating from the Saalfeld region, he held large estates around Weimar, Jena, and Apolda, possibly stemming from late Duke Burchard of Thuringia, whose sons were expelled by King Henry the Fowler in 913.
He was probably married to Adela, a daughter of the Popponid (Elder House of Babenberg) duke Poppo of Thuringia, margrave of the Sorbian March, who had been deposed by the East Frankish king Arnulf in 892. William too appeared in the rank of a Thuringian margrave. From 953 to 955, he and several Wettin counts joined the revolt of Duke Liudolf of Swabia against King Otto the Great, wherefore he was temporarily deposed and exiled to the court of Otto's brother Duke Henry of Bavaria. By 956, however, William was re-installed into his offices.
He had at least three children:
The House of Babenberg was a noble dynasty of Austrian Dukes and Margraves. Descending from the Popponids and originally from Bamberg in the Duchy of Franconia, the Babenbergs ruled the imperial Margraviate of Austria from its creation in 976 AD until its elevation to a duchy in 1156, and from then until the extinction of the line in 1246, whereafter they were succeeded by the House of Habsburg.
Leopold I, known as the Illustrious was a member of the House of Babenberg who ruled as Margrave of Austria from 976 until his death. He was the first margrave of the Babenberg dynasty which ruled the March and Duchy of Austria until its extinction in 1246.
The Duchy of Bavaria was a frontier region in the southeastern part of the Merovingian kingdom from the sixth through the eighth century. It was settled by Bavarian tribes and ruled by dukes (duces) under Frankish overlordship. A new duchy was created from this area during the decline of the Carolingian Empire in the late ninth century. It became one of the stem duchies of the East Frankish realm, which evolved as the Kingdom of Germany and the Holy Roman Empire.
Hermann I, Landgrave of Thuringia and Count Palatine of Saxony, was the second son of Louis II, Landgrave of Thuringia, and Judith of Hohenstaufen, the sister of Emperor Frederick Barbarossa.
The German Emperor was the official title of the head of state and hereditary ruler of the German Empire. A specifically chosen term, it was introduced with the 1 January 1871 constitution and lasted until the abdication of Wilhelm II was announced on 9 November 1918. The Holy Roman Emperor is sometimes also called "German Emperor" when the historical context is clear, as derived from the Holy Roman Empire's official name of "Holy Roman Empire of the German Nation" from 1512.
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.
Henry was the leading military commander of the last years of the Carolingian Empire. He was commander-in-chief under Kings Louis the Younger and Charles the Fat. His early career was mostly restricted to East Francia, his homeland, but after Charles inherited West Francia in 884 he was increasingly active there. During his time, raids by the Vikings peaked in Francia. The sources describe at least eight separate campaigns waged by Henry against the Vikings, most of them successful.
The Luitpoldings were an East Frankish dynasty that ruled the German stem duchy of Bavaria in the ninth century. They are named after their descent from Margrave Luitpold of Bavaria, who reasserted Bavarian autonomy in the early 10th century. His son Arnulf the Bad first assumed the title of Duke of Bavaria.
The Marchof Carniola was a southeastern state of the Holy Roman Empire in the High Middle Ages, the predecessor of the Duchy of Carniola. It corresponded roughly to the central Carniolan region of present-day Slovenia. At the time of its creation, the march served as a frontier defense against the Kingdoms of Hungary and Croatia.
The House of Henneberg was a medieval German comital family (Grafen) which from the 11th century onwards held large territories in the Duchy of Franconia. Their county was raised to a princely county in 1310.
Poppo I, Count of Weimar-Orlamünde, was margrave of Istria from 1012 and of Carniola from 1040 to his death.
Ulric I, also Odalric or Udalrich, Count of Weimar-Orlamünde, was margrave of Carniola from 1045 and of Istria from 1060 to his death.
The House of Andechs was a feudal line of German princes in the 12th and 13th centuries. The counts of Dießen-Andechs obtained territories in northern Dalmatia on the Adriatic seacoast, where they became Margraves of Istria and ultimately dukes of a short-lived imperial state named Merania from 1180 to 1248. They were also self-styled lords of Carniola.
Conrad, called the Old or the Elder, was the Duke of Thuringia briefly in 892–93. He was the namesake of the Conradiner family and son of Udo of Neustria. His mother (probably) was a daughter of Conrad I of Logenahe (832–860). He was the count of the Oberlahngau (886), Hessengau (897), Gotzfeldgau (903), Wetterau (905), and Wormsgau (906). He united all of Hesse under his political control and under his heirs this territory became the Duchy of Franconia.
The Duchy of Thuringia was an eastern frontier march of the Merovingian kingdom of Austrasia, established about 631 by King Dagobert I after his troops had been defeated by the forces of the Slavic confederation of Samo at the Battle of Wogastisburg. It was recreated in the Carolingian Empire and its dukes were appointed by the king until it was absorbed by the Saxon dukes in 908. From about 1111/12 the territory was ruled by the Landgraves of Thuringia as Princes of the Holy Roman Empire. When Frederick IV, the last independent ruler of Thuringia died in 1440, the territory passed to his nephew, the Saxon elector Frederick II.
Sophia of Hungary, a member of the royal Árpád dynasty, was a Margravine of Istria and Carniola from about 1062 until 1070, by her first marriage with Margrave Ulric I, as well as Duchess of Saxony from 1072 until her death, by her second marriage with Duke Magnus Billung.
Otto III. Weimar-Orlamünde, sometimes called Otto IV was a German nobleman. He was a member of the House of Ascania and a titular Count of Weimar-Orlamünde. He was the ruling Count of Weimar and Lord of Rudolstadt and Plassenburg.
The Poppinids were an Frankish dynasty flourising in the early 9th century that originated from Grabfeld. They are named after their descent from Poppo of Grapfeld, who in turn descended from the Robertians. The Popponids gradually evolved into the Elder House of Babenberg. They were related to the Luitpoldings.
