Count Karl-Wilhelm Finck von Finckenstein

Karl Wilhelm Reichsgraf[1] Finck von Finckenstein (11 February 1714 – 3 January 1800) was a Count of the Holy Roman Empire of the German Nation, a Prussian diplomat, and later Prime Minister of Prussia.

He was the son of Count Albrecht Konrad Finck von Finckenstein, who was a field marshal and also governor of the Crown Prince of Prussia, the future King Frederick II.

During the Seven Years' War, Frederick issued a secret decree on 10 January 1757, "in the case of his death or capture", which appointed Finckenstein as Regent of Prussia in that event.

After the end of the Seven Years' War, Finckenstein had sole control of Prussia's foreign relations, and he also had a prevailing influence over the King.

Additionally, the Treaty demanded the unconditionally humane treatment of war prisoner, a novelty at the time.
