Helmold II of Plesse

Family tree: Helmold II. Von Plesse and the Bernhard line
Because only Mathilde's sons - and not their cousins ​​from the Gottschalk line - donated their share of the Berg zu Reinhausen to the monastery there in 1226, Gerhard Streich concludes that, according to the lineage of Count Reinhausen, it is an inheritance from the mother, who therefore (yellow) would either be a Countess Warpke-Lüchow or Blankenburg

Helmold II von Plesse (documented 1191/1213; † before 1226), was a nobleman in the entourage of Duke Henry the Lion and his son Emperor Otto IV and in 1211 commander of a crusade to Livonia .

count

Earlier research assumed that Helmold von Plesse, mentioned in a late document from Heinrich the Lion as a witness in 1191, was Helmold II and Helmold von Plesse, who appeared at the time of Emperor Otto IV, was Helmold III. acts. Since the local Helmold von Plesse was added as the last witness in the document from 1191, he must have been very young, perhaps just of age. Therefore there is now agreement about the identity of the Helmolde from 1191 to 1213, so that he is now counted as Helmold II.

family

Helmold II was the eldest son of the noble free Bernhard I von Höckelheim / Plesse (1170/1190), the founder of the (older) Bernhard line. His mother Mathilde / Mechthild was probably a Countess von Blankenburg or a Countess von Warpke-Lüchow, who presumably bequeathed a third of the castle hill in Reinhausen, on which the monastery stood, to her sons. His brothers were Werner (1197 / -before 1226), Bernhard II. (1209 / -1227) and Poppo von Plesse (1221 / -after 1250). Helmold II did not leave any children entitled to inheritance, because when his two younger brothers Bernhard II and Poppo transferred their share of the castle hill to the Reinhausen Monastery, neither Helmold s sons were involved nor were they included in the family's soul memory.

Ludolf I (1205/1247) and Gottschalk II von Plessen (1205 / -1247 / 1249) were his first cousins. Their father was Gottschalk I. von Höckelheim / Plesse, founder of the (younger) Gottschalk line.

The common grandfather of the four brothers Helmold, Werner, Bernhard and Poppo and their two cousins ​​Ludolf and Gottschalk was probably the Burgmann and later Burgrave Bernhard von Plesse (1150/1183)

Property and family history background

Plesse Castle

Helmold II. Was called after between Gottingen and Northeim lying plesse castle . It originally belonged to the Immedingern and was given to his diocese of Paderborn by Bishop Meinwerk in 1015 . The first known feudal bearer of Plesse Castle was Count Hermann II von Winzenburg (1123 / -1152) . He was murdered in 1152, whereupon Duke Henry the Lion pushed into his vacant fiefdom; in this context, the Guelph probably became Paderborn's Lehnsvasall with Plesse Castle. Since 1150 there was a Bernhard von Plesse (1150/1183) Burgmann, who was last called comes Bernhardus de Plesse in 1183 . He could be the grandfather or a great-uncle of Helmold II. It is believed that after the fall of Heinrich the Lion from 1180/82 onwards, the brothers Bernhard I - Helmold's father - and Gottschalk I von Höckelheim succeeded in being enfeoffed directly with the Plesse Castle by the Bishop of Paderborn, especially the brothers from 1189 only called von Plesse .

Shortly after Helmold II was first mentioned in the entourage of Henry the Lion, Emperor Heinrich VI. (1165–1197) as part of a castle exchange with Bishop Bernhard II of Paderborn (1188–1203) the castrum Plesse nobis et imperio in 1192. In 1195, the year of the death of Duke Henry the Lion, the exchange is reversed. No documents or other news about a connection between Helmold II and Plesse Castle are known apart from his name.

Höckelheim

Höckelheim Monastery at the end of the 16th century

Helmold's father Bernhard I and his brother Gottschalk I called themselves not only von Plesse, but also von Höckelheim. The eponymous place Höckelheim (west of Northeim, now a district) is first mentioned in a document in 1016, when Emperor Heinrich II (973-1024) gave the bishopric of Paderborn the inheritance of Bishop Meinwerk , which Bishop Meinwerk had transferred to his mother Adala and she in turn to the emperor , including Hukilhem .

1070 the noble free Gottschalk - liber Godescalc de Lengede - can be proven not only with possession in Lengede near Göttingen, but also in Höckelheim. He was followed there by Eppo / Erp (1103). His brothers Dietrich (1107/1128) and Gottschalk (1107/1128) also owned Behnsen and Huldesam ; in Hullersen the Lords of Plesse still have rights in 1285. As a result, the brothers Bernhard I and Gottschalk I von Höckelheim / Plesse are to be regarded as descendants of Gottschalk von Lengede not only because of their first name tradition , but above all because of the feudum paternum under feudum paternum - the succession of ownership in the male line. His ancestors came from the dynasty of the Counts of Padberg , who in turn were descendants of the Franco-Alemannic Counts Haolde - followers of Emperor Otto I (912–973).

In 1247 the noblemen Ludolf, Gottschalk and Poppo von Plesse donated their own church and other property in Höckelheim to found a monastery, which became the burial place of the family.

Career

In the wake of the Guelphs

The first document in which Helmold II von Plesse appears as a witness is dated June 6, 1191. Duke Heinrich the Lion and his eldest son Heinrich - who later became the Count Palatine of the Rhine (around 1173–1227) - were the exhibitors. In the cathedral church of St. Blasien in Braunschweig they transferred some hooves to the Walkenried monastery . In the group of secular witnesses, Bernhard zur Lippe (1140–1224) is mentioned as the first and the young Helmold II von Plesse as the twelfth. Twenty years later, on behalf of Pope Innocent III. (1198–1216) and Emperor Otto IV. (1175–1218) started a crusade to Livonia.

Between 1196 and 1197 Helmold II von Plesse was with Count Palatine Heinrich several times. Helmold II and his brother Werner tested for Bishop Gardolf von Halberstadt (1193/1201) in 1197. In 1203 Helmold II worked for Archbishop Siegfried II of Mainz (1200–1230) with the transfer of real estate to the St. Blasius Monastery in Northeim. He also helped Abbot Dietmar II von Corvey (1206–1216) in property matters and tested for King Otto IV for the first time in 1207 in Minden Cathedral , the emblematic wedding church of the ruler's parents. Since then he has been a follower of Otto IV, the lion's youngest son.

King's ride

Helmold II accompanied the ruler in 1208/1209 on his king's ride through the empire. Confirmation as king was necessary because the opposing king - Philip of Swabia - had been murdered on June 21, 1208 in Bamberg by Otto VIII. Count Palatine von Wittelsbach (before 1180–1209). Bernd Ulrich Hucker traced the itinerary of the subsequent king ride. The ride began in the late summer of 1208 in Braunschweig and ended there at Whitsun the following year. In thirty-one places royal official acts were carried out, in whose authentication the ruler's entourage was involved in various ways. The Reichshofmarschall Heinrich von Kalden (before 1175-after 1214), who belonged to the Hohenstaufen emperor Heinrich VI, also belonged to it. (1165–1197), the murdered Staufer King Philip of Swabia (1177–1208), now served the Guelph and later also the Staufer Emperor Friedrich II (1194–1250). On January 6, 1209, Kalden and other Reichsministeriale received the order at the court conference in Augsburg to find and kill the murderer of King Philip of Swabia. Kalden did the job personally on March 7, 1209. Whitsun 1209, the king's ride ended with a court day and knight tournament in Braunschweig. The Quedlinburg coat of arms, one of the oldest heraldic monuments of the Middle Ages, bears witness to this. The gem was by no means created by L'art pour l'art, but is primarily evidence of a knightly society founded by the ruler. Otto IV created this egalitarian community, which broke through all class barriers, based on the example that he had experienced in his youth at the Anglo-Norman royal court and the knight idea cultivated there - in particular the revival of the legendary King Arthur's round table .

Diplomatically, the existence of the knightly society of King Otto IV can be proven in monastery documents from Osterode (Harz) and Mariensee (Calenberg) and also as a symbol of the Great Company , as this society was called in literary evidence of the time. On the jewel there are 33 coats of arms and two knights on their horses in splendid tournament equipment - on the lid in the center the coats of arms of Emperor Otto IV and his closest confidants and highest-ranking representatives at court. On the sides of the box there are 19 more coats of arms, including Helmold II von Plesse. It is the oldest heraldic evidence of the coat of arms of the Lords of Plesse. Their seal tradition began shortly thereafter. The coat of arms shows a wall anchor in silver on red. The color of the anchor later mutated to red on silver.

Rome trip

Soon after the Court Day in Braunschweig, Otto IV set out for Italy. First stations were Goslar, Walkenried, Würzburg, Speyer, Worms (tournament) and Ulm; then collection of the army in Augsburg on the Lechfeld. Here now began the actual procession of the Guelph to Rome, to be there on October 4, 1209 by Pope Innocent III. (1198–1216) to be crowned emperor. The stations of this company largely corresponded to the classic imperial routes. Helmold II von Plesse occupied Buffone Castle near Terni , where the Guelph camped his forces. In Terni himself he helped with notarizations with which Otto IV. - now Kaiser - favored the monasteries Walkenried and Pforte on December 24th and 26th, 1209 respectively .

Crusade to Livonia

Helmold II did not take part in the emperor's march to Sicily; because in 1210 he certified for Bishop Bernhard III. von Paderborn (1204–1223) real estate deals and was probably preparing for the upcoming Livonia Crusade, which was organized at the request of Bishop Albrecht von Riga (1198–1229) to implement Otto IV's imperial policy in the Baltic Sea region. From the chronicle of the Latvian priest Heinrich (around 1187- after 1259), which he wrote around the year 1227, it emerges that in 1211 the noblemen Helmold II von Plesse and Bernhard (rather Hermann) von Lippe (around 1140-1224 ) - accompanied by Bishops Bernhard III. von Paderborn (1204–1223), Yso von Verden (1205–1231) and Philipp von Ratzeburg (1204–1215) - successfully led the crusade against the Estonians.

After the fighting, in 1211 Helmoldus comes de Plessa was the first in the group of secular witnesses to testify to Bishop Adalbert von Riga's privileges for Gotland merchants ( merchants ) and the division of Livonia between Bishop Albert of Riga and the milites Christi - the Order of the Brothers of the Sword - to which, contrary to older views, he himself did not belong, because his name appears diplomatically correct after the clerical witnesses, but before the Brothers of the Sword. In the first of the two documents of division he is called Helmoldus de Plesse nobilis homo - noble lord - in the second simply Helmoldus de Plesse.

Back with the emperor

Helmold II von Plesse was already with Emperor Otto IV in Nordhausen in July 1212 and helped to transfer bailiwick rights to the Walkenried monastery. The last two documents on which he was involved date January 27, 1213. Both were made out in Braunschweig, one for the Emperor, the other for Duke Heinrich of Saxony and Count Palatine of the Rhine, the older brother of the Emperor. Helmold II von Plesse would have been around forty at the time.

Remembrance of the dead and relatives

Reinhausen Monastery, where the monks once prayed for members of the Bernhard Line

Around 1226 Bernhard II and Poppo von Plesse - the youngest brothers of the Livonia driver - renounced their right to the third part of the monastery hill in favor of the Reinhausen monastery. In return, they asked the monks to join their fraternal prayer community - consortium fraternitatem - expressly for themselves and their closest relatives, including their brother Helmoldus . The monks accepted them into their community as if they were all the founders of the monastery (place) - tamquam uni fundatorum loci . This speaks for a close relationship between her mother and the founders of the Reinhausen monastery; because the cousins ​​from the Gottschalk line were present at this transfer, but did not participate in the donation.

This document shows: Around 1226 the parents and their two older sons - Helmold II and Werner von Plesse - were no longer alive; they died with no legitimate offspring. Prayer should be made for the dead as well as for all living relatives, including the brothers Helmold III. and Bernhard III. von Plesse - the two nephews of the Livonia driver. Bernhard III. broke new ground, because under the name de Walia - a place on the Aller near Rethem - he favored the Walsrode monastery in 1221 and 1227 . From 1240 to 1263 de Walia then appeared on a massive scale as a vassal of John I of Mecklenburg (1227–1264); he was the Burgmann of Mecklenburg. In two Mecklenburg documents from 1244 and 1256, de Walia appears together with his brother Helmoldus , who is only called frater eius without being named. There are no other people who bear the Walia name. Because of this and because the brothers also have the leading first names of the von Plesse men, they are the pseudonym for Bernhard III. and the knight Helmold III. from Plesse. They are the nephews of the Livonia driver mentioned in the Reinhausen monastery charter.

The only question that remains unanswered is where the Livonia rider Knight Helmold II von Plesse found his final resting place. Probably hardly in Mecklenburg or in the state of Lüneburg (Walia), but probably quite befitting in the Reinhausen monastery, where his brothers established a prayer community around 1226 for their deceased relatives. To be buried in a monastery whose monks pray for you as if you were one of the founders of the abbey speaks for Reinhausen, especially since the Höckelheim monastery with a burial place for the Lords of Plesse was not yet founded.
