Bavarian Succession, War of The

(1778–79) Conflict in which Frederick II of Prussia prevented Joseph II of Austria from acquiring Bavaria. After the death of the Bavarian elector Maximilian Joseph (1727–77), his successor, Charles Theodore (1724–99), ceded Lower Bavaria to Austria.

Frederick II responded by declaring war (1778). There was little fighting because each force was concerned with cutting its opponent's communications and denying it supplies. Short on supplies, soldiers foraged for potatoes; hence, the conflict was nicknamed the “potato war.” In 1779 Austria and Prussia signed a treaty giving Austria a fraction of the territory originally occupied.
