Sigismund had been looking for some time for an ally capable of helping him to control the expansionist aims of the Swiss Confederates, carried out for the moment at the expense of his territories.
Having sought the support of King Louis XI and having suffered a shrewd refusal on his part, he turned to his rival, Charles the Bold.
[1] The treaty gave Burgundy access to the Rhine and made Charles the Bold, an immediate neighbour of the Swiss.
The management of these territories by the representative of the Duke of Burgundy, the bailiff Peter von Hagenbach, the economic consequences and the loss of the privileges which resulted from it for the Alsatian cities and the Swiss allied cities, seeded a revolt in the territories of Upper Rhine.
This permanent state of military confrontation led to the Battle of Héricourt on 13 November 1474, the first major defeat for the troops of Charles the Bold, a defeat that marked the beginning of the end for the Duke himself and the disappearance of the Duchy of Burgundy in favour of the King of France, Louis XI.
