After escaping her detention in 1425 from the Gravensteen in Gent, Jacqueline, Countess of Hainaut settled in Gouda, which was the capital of the Hook movement at that time.
Jacqueline gathered all her troops from Schoonhoven, Oudewater and Gouda and surprised and defeated the Cod army at the Battle of Alphen aan den Rijn (1425).
However, in the following years, the Hooks suffered several defeats, including the Battle of Brouwershaven, and more and more territory was lost.
By May 1428, Philip the Good had recruited a huge Burgundian army of 20.000 men and raised the siege of Gouda.
By this treaty, hostilities came to an end, Jacqueline retained her titles of Countess of Holland, Zeeland and Hainaut, but she recognized Philip as her heir and regent of her counties.
