The Cologne War (German: Kölner Krieg, Kölnischer Krieg, Truchsessischer Krieg; 1583–1588) was a conflict between Protestant and Catholic factions that devastated the Electorate of Cologne, a historical ecclesiastical principality of the Holy Roman Empire, within present-day North Rhine-Westphalia, in Germany. The war occurred within the context of the Protestant Reformation in Germany and the subsequent Counter-Reformation, and concurrently with the Dutch Revolt and the French Wars of Religion. Also called the Seneschal's War (Truchsessischer Krieg) or the Seneschal Upheaval (Truchsessischer Wirren) and occasionally the Sewer War, the conflict tested the principle of ecclesiastical reservation, which had been included in the religious Peace of Augsburg (1555). This principle excluded, or "reserved", the ecclesiastical territories of the Holy Roman Empire from the application of cuius regio, eius religio, or "whose rule, his religion", as the primary means of determining the religion of a territory.
