The First Utrecht Civil War had been decided in favour of ruling Bishop David of Burgundy. 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. Jan III van Montfoort declared David of Burgundy no longer welcome in the city of Utrecht or in the other cities of the Bishopric and he retired with his partisans to his favourite castle in Wijk bij Duurstede.
