By this treaty the Hook faction promised to support Margaret II, Countess of Hainaut against her rebellious son William of Bavaria.

During his reign the courtier and financer Willem van Duvenvoorde (c. 1290–1353) managed the internal affairs of Holland.

This enabled Van Duvenvoorde and his relatives, the families: Wasseaar, Polanen, Brederode, Boechorst, etc.

When Count William IV got killed during his failed expedition to Friesland in late September 1345, the nobility had long been divided in two parties: pro and contra Van Duvenvoorde, and was arduous to fight.

In early 1346 Margaret II, Countess of Hainaut became count of Holland, Zeeland and Hainault.

She restored order, and made her second son William of Bavaria her lieutenant in Holland.

He was assisted by a council that was again dominated by Van Duvenvoorde, and so nothing was done to quiet the nobility and rebellious cities.

On 21 September 1350 Margaret and William of Bavaria then came to Geertruidenberg, where she deposed him of all authority in Holland.
