The unexpected death of Burgundian Duke Charles the Bold in 1477, who was succeeded by his young and inexperienced daughter Mary of Burgundy, opened the floodgates of latent anti-Burgundian sentiments in the Netherlands.
He and his army then sought refuge in the Sticht where they stood under the protection of the energetic and ferocious Viscount Jan of Montfoort, leader of the anti-Burgundian forces in the bishopric.
The Viscount, with the support of the Zoudenbalchs and other anti-Burgundian notables, then effectively staged a coup in the city government of Utrecht, ejecting the pro-Burgundian regents from their offices and thus ensuring that the council was fully committed to the Hook cause.
The Hooks of Utrecht were well aware of the weakness of their position and they thus sought an alliance with King Louis XI of France, the arch-enemy of Maximilian - but ultimately to no avail.
Only back in control of the city of Utrecht since 21 April 1483, Prince-Bishop David of Burgundy was surprised in his old episcopal palace by a daring and stealthy night raid of the Hooks on 8 May.
