The count's sister Irmgard was married to Lothair Udo III, Margrave of the Nordmark, and was the mother of Helperich's successor in ruling the margraviate, Henry II.\nHelperich inherited the title Count of Pl\u00f6tzkau upon his father\u2019s death and the title Count of Walbeck from his mother, although this title was mostly ceremonial at this point.  In 1112, Emperor Henry V deposed Rudolf I as Margrave of the Nordmark because of conspiracy against the crown in his alliance with Lothair of Supplinburg, then Duke of Saxony (and later Holy Roman Emperor).  The margraviate was given to Helperich as an interim measure until Henry II, nephew of Rudolf and heir to the title, was of age.\nIn 1106, Helperich married Adele, daughter of Kuno of Northeim and Kunigunde of Weimar-Orlam\u00fcnde, widow of Dietrich III, Count of Katlenburg.

Brother of his predecessor Henry I the Long.\nLothair Udo was betrothed to Eilika of Saxony, daughter of Magnus, Duke of Saxony, and Sophia of Hungary. However, his attention was diverted to the House of Helperich, towards Count Helperich's enticing sister Ermengardam.  He married this woman, the count's sister Irmgard, daughter of Dietrich, Count of Pl\u00f6tzkau, and Mathilde von Walbeck, daughter of Conrad, Count of Walbeck.  Eilika moved on and married Otto the Rich, Count of Ballenstedt, and was mother to Albert the Bear, the last Margrave of the Nordmark and first Margrave of Brandenburg.  This provides an interesting twist in the history of the county of Stade.\nLothair Udo and Irmgard had four children:\n\nHenry II, Margrave of the Nordmark, also Count of Stade (as Henry IV)\nA daughter whose name is not known\nIrmgard von Stade, married Poppo IV, Count of Henneberg\nAdelheid von Stade, married Henry II, Margrave of Meissen.Lothair Udo was succeeded by his brother Rudolf as margrave and count upon his death.\n\nSources\nHucke, Richard G., Die Grafen von Stade. 900\u20131144.

His father Otto I promoted and directed the foundation of German settlement in the area, which had been Slavic until the 10th century.\n\nCount of Arneburg\nAlbert II was, from 1184 onwards, Count of Arneburg in the Altmark.  The Altmark belonged to Brandenburg, and his older brother Otto II claimed that this implied that the Ascanians owned Arneburg.\nWhen Henry of Gardeleggen died in 1192, he left his domains to Albert II. But that caused a conflict between himself and his brother. He was temporarily imprisoned in 1194 by Otto.\nIn 1197, he joined the German Crusade of 1197. He was present at the inaugural meeting of the Teutonic Knights in 1198 in Acre.\n\nMargrave of Brandenburg\nAlbert II inherited the Margraviate in 1205, after the death of his eldest brother Otto II.\nIn the dispute about the imperial crown between the Houses of Hohenstaufen and Guelph in the early 13th century, Albert initially supported the Hohenstaufen King Philip of Swabia, like Otto before him.  After Philip's assassination in 1208, however, he changed sides, because Emperor Otto IV had assisted him in securing the Margraviate against the Danes, and had confirmed Ascanian ownership of Brandenburg in a deed in 1212.\nDuring this period, Albert II had a lengthy dispute with Archbishop Albert I of Magdeburg. He also played an important r\u00f4le in the Brandenburg tithe dispute.\nAlbert II definitively secured the regions of Teltow, Prignitz and parts of the Uckermark for the Margraviate of Brandenburg, but lost Pomerania to the House of Griffins.\n\nDeath and succession\nAlbert II died in 1220.  At the time, his two sons were still minors.  Initially, archbishop Albert I of Magdeburg acted as regent.  In 1221, however, Albert's widow, Countess Matilda, took up the regency.  After her death in 1225, the brothers were declared legal adults and began ruling the Margraviate jointly.\n\nLegacy\nStephan Warnatsch describes Otto I's children as follows:[They] continued the territorialisation drive that had been initiated [by their father] and, from the end of the 12th Century, as the influx of settlers grew stronger, and, consequently, more people were available to develop the territory, started to expand into the areas of Ruppin, and in particular, Barnim and Teltow.  Moreover, the Oder region and the southern Uckermark were also targets of the Ascanian expansion.  In all these areas, the Ascanians ran into opposition from competing local princes.\n\nMarriage and issue\nIn 1205, Albert married Matilda of Groitzsch (1185\u20131225), daughter of the Count Conrad II of Lusatia, a member of the House of Wettin, and wife Elizabeth, from the Polish Piast dynasty.  They had four children:\n\nJohn I (born: c.\u20091213; died: 4 April 1266)\nOtto III \"the Pious\" (born: 1215; died: 9 October 1267)\nMatilda (died: 10 June 1261), married in 1228 Duke Otto I \"the Child\" of Brunswick-L\u00fcneburg (1204\u20131252), a member of the House of Guelph\nElizabeth (born: 1207; died: 19 November 1231), married in 1228 Landgrave Henry Raspe of Thuringia (1201\u20131247)\nPassage 4:\nHenry II, Margrave of Baden-Hachberg\nHenry II, Margrave of Baden-Hachberg (before 1231 \u2013 c.\u20091297/1298) was the ruling Margrave of Baden-Hachberg from 1231 to 1289.\n\nLife\nHenry II was the eldest son of Margrave Henry I of Baden-Hachberg and his wife, Agnes, a daughter of Count Egino IV of Urach.  In 1231, he succeeded his father as Margrave of Baden-Hachberg.  Since he was a minor at the time, he initially stood under the guardianship of his mother.  He was the first in his line of the House of Z\u00e4hringen to style himself Margrave of Hachberg.  In 1232, he purchased the Lordship of Sausenburg from St. Blaise Abbey.  Soon afterwards, he built Sausenburg Castle, which was first mentioned in 1246.He had disputes with the spiritual rulers in the area and with the Counts of Freiburg about the entangled rights and privileges they had (or claimed to have) on each other's possessions.  In 1250, some imperial and Hohenstaufen possessions became available for the taking after Emperor Frederick II had died.  Henry II grabbed some of these land and managed round off his territory.\nFor several years, he supported Count Rudolph of Habsburg in his disputes against the bishops of Basel and Strasbourg.  In 1273, he supported Rudolph in his bid to become King of the Romans.  He also supported Rudolph in his dispute against the main line of the Margraves of Baden.  During the war against Bohemia, Henry II fought on the imperial side in the decisive Battle on the Marchfeld.\nHe was a patron of the monasteries Tennenbach and Adelhausen.Henry II abdicated in 1289, and joined the Teutonic Knights.\n\nMarriage and issue\nHenry II was married to Anne, a daughter of Count Rudolph II of \u00dcsingen-Ketzingen.  They had the following children:\n\nHenry III, his successor as Margrave of Baden-Hachberg\nRudolf I, the first Margrave of Hachberg-Sausenberg\nFrederick, who also joined the Teutonic Knights\nVerena, married Egino I, Count of F\u00fcrstenberg\nHerman I, joined the Knights Hospitaller\nKunigunde, a nun at Adelhausen\nAgnes, married Walter of Reichenberg\nElisabeth, also a nun at Adelhausen\nPassage 5:\nHenry II, Margrave of the Nordmark\nHenry II (1102 \u2013 4 December 1128), Margrave of the Nordmark, also Count of Stade (as Henry IV), son of Lothair Udo III, Margrave of the Nordmark, and  Irmgard, daughter of Dietrich, Count of Pl\u00f6tzkau, and Mathilde von Walbeck.\nHenry assumed the title of Margrave of the Nordmark in 1114 from Helperich of Pl\u00f6tzkau, who was appointed margrave until Henry came of age. The previous margrave in this dynasty was Henry\u2019s uncle Rudolf I, who was also his guardian.  Rudolf was deposed by Emperor Henry V because of conspiracy against the crown, and was replaced by Helperich as an interim measure.  Henry assumed the titles of Count of Stade and Margrave of the Nordmark in 1114.\nHenry was married to Adelaide of Ballenstedt, a daughter of Otto, Count of Ballenstedt, and Eilika of Saxony.  Adelaide was therefore the sister of Albert the Bear. There are no known children as a result of this union.  Henry was succeeded as margrave by the son of Helperich, Conrad of Pl\u00f6tzkau.\n\nSources\nKrause, Karl Ernst Hermann, Lothar Udo II. und das Stader Grafenhaus. In: Allgemeine Deutsche Biographie. Band 19, Duncker & Humblot, Leipzig, 1884\n\n\n== External links ==\nPassage 6:\nHenry II, Margrave of Meissen\nHenry II (1103\u20131123) was the Margrave of Meissen and the Saxon Ostmark (as Lusizensis marchio: margrave of Lusatia) from his birth until his death. He was the posthumous son of Margrave Henry I and Gertrude of Brunswick, daughter of Egbert I of Meissen. He was by inheritance also Count of Eilenburg. He was the second Meissener margrave of the House of Wettin.\nHe was initially under the regency of first his mother and after her death in 1117 under his great uncle Thimo. He died young and without children in 1123. His lands were inherited by his half-sister Richenza of Northeim. He left a widow, Adelaide, daughter of Lothair Udo III, Margrave of the Nordmark. The succession to the marches was disputed after his death.\nPassage 7:\nRudolf II, Margrave of the Nordmark\nRudolf II (died 14 March 1144), Margrave of the Nordmark, and Count of Stade, Dithmarschen and Freckleben, son of Rudolf I, Margrave of the Nordmark, and Richardis, daughter of Hermann von Sponheim, Burgrave of Magdeburg.\nRudolf, the traditional heir to the margraviate assumed the title upon the death of his predecessor Conrad von Pl\u00f6tzkau.\nA chronicle of the 15th century reported that Rudolf resided in Burg, Dithmarschen (B\u00f6kelnburg). He ruled with a heavy hand and demanded his grain tithe even after several years of drought. The Dithmarscher farmers used a ruse to get rid of their unpopular regent. Hidden in sacks of corn were weapons.  As agreed, they opened the bags at the sound of the battle cry \"R\u00f6hret de Hann, snidet de sac spell!\" (Shall ye touch hands, cuts the bag volumes). They set the castle on fire, killed the count and so won their freedom. This event is still recounted today in performances at the castle. His widow, Elizabeth, later married Henry V, Duke of Carinthia.Rudolf was married to Elisabeth, daughter of Leopold I the Strong, Margrave of Styria. No children are recorded of this union. With the death of Rudolf, the male line of the Margraves of the Nordmark died out.\nAfter the death of Rudolf, his brother Hartwig transferred his inheritance to the Archbishopric of Bremen in return for a regrant of a life interest, presumably to obtain a powerful protector against the aggression of Henry the Lion.  The move was ineffective, as Henry took possession of the lands and captured both Hartwig and the archbishop Adelbero, releasing them only after they agreed to recognize his claim.\nRudolf\u2019s successor as Margrave of the Nordmark was Albert the Bear.  Upon Rudolf's death, his brother Hartwig succeeded him as Count of Stade.\nPassage 8:\nHenry I the Long, Margrave of the Nordmark\nHenry I the Long (c. 1065 \u2013 27 June 1087), Margrave of the Nordmark, also Count of Stade (as Henry III), son of Lothair Udo II, Margrave of the Nordmark, and Oda of Werl, daughter of Herman III, Count of Werl, and Richenza of Swabia.\nHenry married Eupraxia of Kiev, daughter of Vsevolod I, Grand Prince of Kiev, and his second wife Anna.  There were no children as a result of this marriage, and Eupraxia, widowed, married next Henry IV, then King of Saxony, who became Holy Roman Emperor.\nRaffensperger suggests that Henry's motivation in marrying Eupraxia was to bring Saxony closer to Kiev.  In fact, the marriage may have been arranged by Oda of Stade, daughter of Lothair Udo I, Margrave of the Nordmark, who had married Sviatoslav II, Grand Prince of Kiev. Oda is identified as a relative of Henry\u2019s father Lothair Udo II as well as a niece of Henry III, Holy Roman Emperor, and Pope Leo IX.\nUpon his death, Henry was succeeded as margrave and count by his brother Lothair Udo III.\n\nNotes\nSources\nVernadsky, George, Kievan Russia, Yale University Press, New Haven, Connecticut, 1948, ISBN 9780300010077\nRaffensperger, Christian, Reimagining Europe: Kievan Rus' in the Medieval World, Harvard University Press, Cambridge, Massachusetts, 2012\nH.

He was the second son of Otto II, Margrave of Meissen and Hedwig of Brandenburg.\n\nBiography\nTheodoric, called in German Dietrich, the younger son of Otto II, Margrave of Meissen, fell out with his brother, Albert the Proud, after his mother persuaded his father to change the succession so that Theodoric was given the Margraviate of Meissen and Albrecht (although the older son) the margraviate of Weissenfels. Albert took his father prisoner to try to make him return the succession to the way it had been. After Otto obtained his release by an order of the emperor Frederick I, he had only just renewed the war when he died in 1190. Albert then took back the Meissen margraviate from his brother. Theodoric attempted to regain the margraviate, supported by Landgraf Hermann I of Thuringia, his father-in-law. In 1195, however, Theodoric left on a pilgrimage to Palestine.\n\nAlbrecht's Death\nAfter Albrecht's death in 1195, leaving no children, Meissen, with its rich mines, was seized by the emperor Henry VI as a vacant fief of the empire. Dietrich finally came into possession of his inheritance two years later on Henry's death.\nAt the time of the struggle between the two rival kings Philip of Swabia and Otto IV, Holy Roman Emperor, Phillip gave Dietrich the tenure of the march of Mei\u00dfen again. After that time, Dietrich was on Phillip's side and remained true to the Staufer even after Phillip was murdered in 1208.\nDietrich became caught up in dangerous disagreements with the city of Leipzig and the Mei\u00dfen nobility. After a fruitless siege of Leipzig, in 1217 he agreed to a settlement but then took over the city by trickery, had the city walls taken down and built three castles of his own within the city, full of his own men.\n\nDeath\nMargrave Dietrich died on 18 February 1221, possibly poisoned by his doctor, instigated into doing so by the people of Leipzig and the dissatisfied nobility. He left behind a widow, Jutta of Thuringia, daughter of Hermann I, Landgrave of Thuringia. Some of his children had already died.\n\nMarriages and issue\nChildren from his marriage to Jutta of Thuringia, daughter of Hermann I, Landgrave of Thuringia:\nHedwig (d. 1249) married Count Dietrich V of Cleves (1185\u20131260)\nOtto (d. before 1215)\nSophia (d. 1280) married Count Henry of Henneberg-Schleusingen (d. 1262)\nJutta married Mestwin II, Duke of Pomerania\nHenry the Illustrious (1218\u20131288) Margrave of MeissenChildren from extramarital liaisons:\n\nKonrad\nDietrich II (not the same as Dietrich von Kittlitz)\nHeinrich\nPassage 10:\nWilliam, Margrave of the Nordmark\nWilliam (died 10 September 1056) was the Margrave of the Nordmark from 1051 until his death. He was the eldest son and successor of the Margrave Bernard by a daughter of Vladimir the Great. He died fighting the Slavs in the Battle of Pritzlawa. Upon his death, he was succeeded by his half-brother Otto as Margrave of the Nordmark.\n\nSources\nBury, J. B.
