The conflict arose after Duke
Waleran IV of Limburg, a scion of the Lotharingian
Ardennes-Verdun dynasty, had died without male heirs in 1279. His duchy was inherited by his daughter
Ermengarde, who had married Count
Reginald I of Guelders about 1270. Ermengarde's husband claimed the Limburg heritage and in 1282 had his ducal title recognized by the German king
Rudolf I. The marriage of Reginald and Ermengarde, however, remained childless and when she died in 1283, Count
Adolf VIII of Berg, Duke Waleran's nephew as son of his elder brother Count
Adolf VII, also claimed the Limburg duchy. As far as the succession in the female line was denied, Reginald was unable to assert his claims. An agreement seemed possible; nevertheless, Adolf of Berg preceded his Ardennes relatives when in September 1283 he sold his claims to the mighty
Reginar duke John of Brabant. John intended to enlarge his
Brabant territory and re-unite the former Duchy of
Lower Lorraine in the northwest of the
Holy Roman Empire. Limburg was also economically important as it stretched along the major
Via Regia trade route to
Aachen and
Cologne on the
Rhine river. Though John held the title of
Duke of Lothier since 1190, it had been solely honorific and did not imply any inheritance claims. The Limburg nobles therefore refused to accept John's overlordship, when his forces invaded the duchy. Between 1283 and 1288, the conflict was delayed by several smaller confrontations between both sides, none of them decisive. Meanwhile, most of the other local powers chose sides. Siegfried II of Westerburg, the
Archbishop of Cologne, suspiciously eyed John's increasing power in the Lower Lorraine lands. In view of their common interests, he and Reginald of Guelders forged an alliance in August 1284, joined by Count
Henry VI of Luxembourg, and his brother
Waleran I of Ligny, as well as by Count
Adolf of Nassau. On the other side the Westphalian counts of
Mark took the chance to affirm their independence from the Archbishop of Cologne and together with the Counts of
Loon,
Tecklenburg and
Waldeck allied with Brabant and Berg. == Battle ==
