The Cologne Diocesan Feud (German: Kölner Stiftsfehde, or Stiftsfehde zu Köln), also called the Neuss War (Neusser Krieg) or Burgundian War (Burgundischer Krieg), was a conflict, which began in 1473, between the Archbishop of Cologne, Ruprecht of the Palatinate and the Landstände of his archbishopric. As a result of the involvement of Charles the Bold of Burgundy and, eventually, the Holy Roman Empire the matter at times assumed a European dimension. It finally ended when Ruprecht died in 1480.
