The Cologne Diocesan Feud, also called the Neuss War (Neusser Krieg) or Burgundian War (Burgundischer Krieg), is a conflict between the Archbishop of Cologne, Ruprecht of the Palatinate and the Landstände of his archbishopric, that begins in 1473.
As a result of the involvement of Charles the Bold of Burgundy and, eventually, the Holy Roman Empire, the matter at times assumes an international dimension.
