Otto IV, Count of Ravensberg
Otto IV, Count of Ravensberg( – 1328) was a German nobleman.
He was the ruling Count of Ravensberg from 1306 until his death.

Gerhard V of Jülich
Gerhard V of Jülich( before 1250 – 29 July 1328), Count of Jülich( 1297 – 1328), was the youngest son of William IV, Count of Jülich and Richardis of Guelders, daughter of Gerard III, Count of Guelders.
Gerhard succeeded his brother Walram as Count of Jülich in 1297.
He supported King Adolf in the Battle of Göllheim in 1298, but when Adolf was killed by King Albert I, Gerhard submitted to Albert and was allowed to keep his imperial fief.
He helped Albert against the Rhenish electors in 1300, which confirmed his interests with respect to Cologne.
Gerhard also won the river duties of Kaiserswerth, Mönchen- Gladbach, Kessel- Grevenbroich, Rheydt, Münstereifel/ Bergheim and Müllenark, among others.
In 1313, Gerhard supported Ludwig IV in the succession war for the throne of Germany and allowed Ludwig's coronation in Aachen against the will of the Archbishop of Cologne.
Gerhard VI of Jülich, Count of Berg and Ravensberg
Gerhard VI of Jülich, Count of Berg and Ravensberg (– 18 May 1360) was the son of William V, Duke of Jülich and Joanna of Hainaut.
Gerhard was betrothed in 1333 (renewed 1342) to Margaret of Guelders, daughter of Rainald II of Guelders and Sophia Betrout.
However, this marriage was never consummated, likely due either to Rainald's death in 1343 or Margaret's death in 1344.<br>
Gerhard was subsequently married about 1344 to Margaret of Ravensberg, heiress of Berg and Ravensberg (died 13/19 February 1389), daughter of Otto IV, Count of Ravensberg and Margaret of Berg.
Margaret's father Otto had no sons so at his death in 1328, the County of Ravensberg went to his brother Bernhard.
However, when Bernhard died in 1346 without issue, Margaret became the heir of Ravensberg, her elder sister Hedwig having died in 1336.<br>
Then, when Margaret's uncle, Count Adolf IX of Berg, died in 1348 without issue, Margaret also inherited Berg by right of her mother.
Thus, the titles to Berg and Ravensberg came into the house of Jülich where they remained until 1511 when they passed into the house of Cleves.
Gerhard completed several ineffective protective alliances and stood against the Archbishop of Cologne.
He won Hardenberg, Neviges, Langenberg, Remangen and Kaiserswerth, among others.
Gerhard died 18 May 1360 in a tournament in Düsseldorf and is buried with his wife in the Altenberg Abbey.
Margaret of Jülich
Margaret of Jülich( – 10 October 1425) was a daughter of Duke Gerhard VI of Jülich and his wife, Margaret of Ravensberg( 1315- 1389).
In 1369, she married Adolf III of the Marck.
She had fourteen children with him, at least five of whom did not survive infancy.
William VIII of Jülich, Count of Ravensberg
William VIII of Jülich, Count of Ravensberg (– 22 November 1428) was the youngest son of William VII of Jülich, 1st Duke of Berg and Anna of the Palatinate.
Along with his brother, Adolf, William rebelled against his father but surrendered in 1404 and received his father's title as Count of Ravensberg which he held until his death in 1428.
In 1401, William was appointed Bishop of Paderborn by Pope Boniface IX through the influence of his uncle, Rupert, King of Germany.
William's elder brother Rupert had held the same post from 1389–1394.
Like his uncle, King Rupert, William was a follower of the Roman Popes.
As Prince-Bishop, William aroused heavy unrest with his ecclesiastical reform effort and quarreled with Waldeck and Lippe, compelling acknowledgement of Paderborn's sovereignty over parts of Lippe.
Despite territorial policy successes, he faced opposition and renounced Paderborn in 1414.
He attempted to become Archbishop of Cologne but failed against Dietrich of Moers who also replaced William as Bishop of Paderborn.
William then married Dietrich's niece, Adelheid of Tecklenburg, and became the father of the new line of the Dukes of Jülich-Berg and Counts of Ravensberg, when his brother Adolf died without an heir.
William and Adelheid are buried in the Stiftskirche in Bielefeld.
William V, Duke of Jülich
William V, Duke of Jülich( – 25/26 February 1361) was a German nobleman.
Some authors call him William I, because he was the first" Duke of Jülich"; the earlier Williams had been" Count of Jülich".
Other authors call the subject of this article" William VI"; they count the son and co-ruler of William IV as William V. William V was the eldest son of Gerhard V of Jülich and Elisabeth of Brabant- Aarschot, daughter of Godfrey of Brabant.
William V was a key political figure of his time, being a brother- in- law to both Edward III of England and Emperor Ludwig IV.
He spent enormous sums of money to have his brother Walram of Jülich appointed as Archbishop of Cologne over Adolph II of the Marck.
In 1337 he was crucially involved in the German- English alliance which caused the start of the Hundred Years' War. William was an important supporter of Emperor Ludwig and for a time, he supported the Habsburgs against the House of Luxembourg in the Carinthian war of succession.
Upon the collapse of the German- English alliance and the death of his brother- in- law, William switched his allegiance to Emperor Charles IV.
In 1352 he initiated an inheritance tax on Heinsberg- Valkenburg/ Monschau.
William won important positions through his Archbishop brother and also served for a time as a field captain for Flanders in the Hundred Years' War.
His sons fought against him during an uprising of part of the Jülich knighthood which opposed inclusion in the increasing territorial state, and he was imprisoned by them in 1349, but released in 1351 due to public pressure.
Upon his father's death in 1328, William became Count of Jülich.
In 1336 William was appointed Margrave by his brother- in- law, Emperor Ludwig IV, and in 1356/ 57 he was raised to the level of Duke by Emperor Charles IV, thus becoming the first Duke of Jülich.
His skillful marriage policy, especially the marriage of his son Gerhard to Margaret of Ravensberg, heiress of Berg and Ravensberg, enabled him to add territory to the house of Jülich.
Upon William's death in 1361, the Duchy of Jülich passed to his second son, William, his eldest son having predeceased.
William and his wife are buried in Nideggen.
He seems to have held the title of Earl of Cambridge from 1340 to his death.
William VII of Jülich, 1st Duke of Berg
William VII of Jülich, 1st Duke of Berg (– 25 June 1408) was born in Jülich, as the son of Gerhard VI of Jülich, Count of Berg and Ravensberg, and Margaret, daughter and heiress of Otto IV, Count of Ravensberg, and Margaret of Berg.
Upon his father's death in 1360, William became Count of Berg and Ravensberg, a title that his father had gained by marrying the heiress of Berg and Ravensberg.
In 1380, King Wenzel elevated him to the rank of Duke, thus becoming the first Duke of Berg.
William fought the counties of Mark and Cleves to prevent them from combining but in 1397 he was taken prisoner in the battle of Kleverhamm.
He lost Remagen, Kaiserwerth and Sinzig to his nephew Adolf IV, Count of Kleve-Mark and due to these losses, his sons turned against him and imprisoned him in 1403/04.
He ultimately forced them to submit and later supported his brother-in-law Rupert, King of Germany against Guelders-Jülich and won the county of Blankenburg.
William died on 25 June 1408 and is buried in the Abteikirche in Altenberg.
Margaret of Ravensberg
Margaret of Ravensberg (– 13 February 1389) was the daughter and heiress of Otto IV, Count of Ravensberg and Margaret of Berg-Windeck.
Margaret's father, Otto, had no sons, so at his death in 1328, the County of Ravensberg went to his younger brother Bernhard.
However, when Bernhard died in 1346 without issue, Margaret became the heiress of Ravensberg, her elder sister and only sibling, Hedwig, having died in 1336.
Then, when Margaret's uncle, Adolf IX of Berg, died in 1348 without issue, Margaret also inherited Berg by right of her mother, since Margaret was Adolf's only surviving niece.
As a result of her marriage to Gerhard VI of Jülich, Berg and Ravensberg passed into the house of Jülich where they remained until 1511 when they passed into the house of Cleves.
Gerhard VII, Duke of Jülich-Berg
Gerhard VII, Duke of Jülich- Berg( – 19 August 1475) was the son of William VIII of Jülich, Count of Ravensberg and Adelheid of Tecklenburg.
Gerhard was the second duke of the combined Duchy of Jülich- Berg but the 7th Gerhard in the House of Jülich.
Upon his father's death in 1428, Gerhard became Count of Ravensberg.
In 1437, his uncle Adolf died without heirs and Gerhard inherited his title as Duke of Jülich- Berg.
Gerhard continued his uncle's fight for the dukedom of Guelders, supported by King Albert II of Germany.
In 1444 he won the Battle of Linnich but was unable to prevail in his fight for Guelders and ultimately sold his claim to Burgundy and acquired Blankenheim- Löwenberg and Heinsberg from Guelders.
He was increasingly unable to govern his territories after 1461.
His spouse Sophie of Saxe- Lauenburg then wielded regency for him.
