Sibet Lubben

East Frisia at the time of the chiefs .

Sibet Lubben, also called Sibet Lubbenson or Sibet von Rüstringen , (attested in 1416 ; † 1433 ) was an East Frisian chief to Rüstringen and Östringen .

Life

Sibet Lubben was the son of the Lubbe Sibets (attested 1397–1420), the chief of Burhave in Butjadingen , from his first marriage to Frouwa, the daughter of Edo Wiemken the Elder (attested from 1382–1415). Since Edo Wiemken's only son Dodeko had died in 1391, he bequeathed the chieftain's rights in his home country, the Bant district of Rüstringen , to his grandson Sibet.

In a letter from Wilhelm II , Duke of Straubing-Holland , dated August 11, 1416, he was first attested as "hovelinge to Rustringe".

Sibet, although initially only a local chief, pursued a policy of power expansion, presumably inspired by the example of his grandfather and the rise of the East Frisian chieftain family Tom Brok . His first marriage was with a daughter of Keno II tom Brok .

With his grandfather's chief castle Edenburg , which he renamed Sibetsburg in 1416 , as a base, his urge to expand was directed to Östringen in the northwest and east to the Lower Weser . Through alliances with his father in Burhave, his brother Memme in Waddens and other local chiefs, he tried to gain sovereignty over the area once controlled by Edo Wiemken the Elder.

However, his success was initially only minor. As early as 1418, Butjadinger farmers rose against Sibet's rule and his tax demands. Through an alliance with Count Christian VI. von Oldenburg he was able to consolidate his power militarily at first, but he could not prevent the Butjadingers from placing themselves under the protection of the city of Bremen in 1419 and driving out the local chiefs with their help. Even with a constructed legal claim to the obedience of the peasants, he did not penetrate the strong Hanseatic city.

In Östringen, too, Sibet's expansion efforts initially only had short-term success. From 1417 he was able to extend his rule to Jever , but in 1420 the city was conquered by his brother-in-law, Ocko II. Tom Brok , son Kenos II. Sibet then had to renounce this claim to power and leave Ocko the associated rights to rule in the Wangerland . In the same year, with a document dated October 23, 1420, both concluded an alliance for the protection and for the freedom of Friesland against "dudesche heren ofte cities" and Sibet initially concentrated only on its ruined area.

In 1424 he took part in a campaign in which Ocko tom Brok and Focko Ukena , chiefs of the Moormer and Lengen lands , invaded the Stadland , allegedly to avenge the execution of the sons of Dide Lubben in Bremen in 1419. Through his participation, Sibet hoped to be able to enforce claims for power in the Frisian Wesermarsch . On July 29, 1424 a peace agreement was made in Oldenburg . Bremen could not hold the area, but subsequently prevented the establishment of a new chief rule and the transfer of the Friedeburg to Sibet. The castle was demolished in 1425.

As a result, the alliance between Ocko tom Brok and Focko Ukena disintegrated, which Sibet saw again the opportunity to expand his rule in Östringen. Sibet took sides with Focko, whose daughter Ammeke he had married in his second marriage around 1423. Since May 1425 he called himself chief of Rüstringen and Östringen again , which suggests that he had brought Jever back into his rule at that time. On September 27, 1426, the peasant East Frisian troops led by Focko and Sibet defeated a Bremen-Oldenburg army of knights in the Battle of Detern after Count Dietrich von Oldenburg left his allies in the course of the battle. In the following years Sibet had to bow to increasing autonomy efforts of the rural communities in eastern Friesland, Östringen and Rüstringen and in 1427 undertook to demolish Jever Castle. However, he was able to maintain his position and authority as the country chief.

He also held on to the close alliance with Focko Ukena and thus got into his dispute with the Greetsiel chief family Cirksena and the rural freedom movement led by them, the Freedom League of the Seven East Friesland .

Around 1430 Focko suffered a defeat against this alliance, but Sibet was subsequently able to bind the countries under his rule Rüstringen, Östringen and Wangerland to himself. He was able to repel several attacks by the Freedom League and its allies in Oldenburg and Bremen on his Sibetsburg, for example through his victory at Schaar on May 29, 1432. In the subsequent peace treaty of June 14, 1432, the unsuccessful rural communities of Sibets confirmed their rule over the Sibetsburg castles, Jever and Friedeburg in Östringen.

Sibet supported the Vitalienbrüder , whom he offered shelter on the Sibetsburg, among other places. He justified this in 1432 by having to take revenge for his grandfather Edo Wiemken, who was taken prisoner in 1405 in connection with the Hanseatic- Dutch conflict and was only released against a ransom. Thereby he provoked the Hanseatic League and in June 1433 the city of Hamburg sent an expeditionary corps under the leadership of Simon from Utrecht to East Frisia. The troops were able to conquer Emden Castle from Sibet's allied chief Imel Abdena , who also supported the Vitalienbrüder. Sibet and his brother-in-law, the chief Udo von Norden, gathered a relief army, but were defeated on July 29, 1433 by East Frisian and Hamburg troops near Bargebur . Sibet was wounded in battle and died a few days after the battle. Subsequently, Sibetsburg, at the time defended by his half-brother Hayo Harlda (attested in 1420; † 1441), was occupied in early September 1433. In 1435 it was razed.

Succession

Sibet had no children from his two marriages, so Hayo Harlda and his brother-in-law Lubbe Onneken (attested 1433; † 1476) became his successor.
