Life

Wilhelm von Aarberg-Valangin came from a sideline of the dynasty of the Counts of Aarberg and was a son of Johann II von Aarberg-Valangin († 1383) and his wife Mahaut von Neuenburg-Blamont († 1410). He lost his father when he was only six years old and was then under the tutelage of his mother. He allowed him to continue to have a say in the government even after he had reached the age of majority. When the Bernese took possession of the county of Aarberg, Wilhelm’s mother was annoyed that she had claimed that county herself. As a result, she terminated the castle rights contract that her husband had entered into with Bern, did not pay the ransom of 1200 guilders stipulated in this contract and instead supported Duke Leopold III during the Swiss Habsburg Wars. of Austria , who fell in the battle of Sempach on July 9, 1386 . In retaliation, the Bernese devastated the Val de Ruz as well as Hasenburg and Willisau . Mahaut then acted more cautiously and concluded a new castle law agreement with Bern in 1401. Two years later, she also agreed an alliance with Biel .

In 1406 Wilhelm and his mother gave Valangin what is known as the Grand Franchise ; as a result, the inhabitants of Valangin now had the same rights as the citizens of Neuchâtel with regard to their person and property . Wilhelm fell out with his feudal lord, the Count of Neuchâtel, and with the Bernese. As a result, as well as due to his participation in the Council of Constance and in the fighting in the Italian theater of war, he got into considerable debt. His marriage in 1407 to the wealthy heiress Jeanne von Bauffremont , through whom the Baron Bauffremont in Lorraine came into his possession, did little to alleviate his precarious financial situation. His son Johann emerged from his marriage to Jeanne , who was to succeed him as Herr von Valangin. In order to improve the financial situation of his rule, Wilhelm sold Willisau to the city of Lucerne in 1407 and later ordered in his last will that his son would have to serve a higher noble for several years. Furthermore, his son was supposed to avenge the insults allegedly inflicted on him by the new lords of Neuchâtel, Count Konrad and Johann von Freiburg. Wilhelm died in 1427 at the age of about 50.
